US presidential hopeful Donald Trump has said it is a "great thing" that the people of the UK have "taken back their country" in voting to leave the EU.

His comments came as he arrived at Trump Turnberry for the reopening of the refurbished Open venue golf resort.
Mr Trump added his name to the Ayrshire hotel and golf course after buying the resort for an undisclosed fee in 2014.
Comedian Simon Brodkin later disrupted Mr Trump's news conference by waving golf balls with a swastika on them.
The presumptive Republican nominee was also the subject of a small protest by those who accuse him of "racism and bigotry" during his bid for the presidency.
Dozens of people, with placards stating "No To Racism", gathered outside the resort before Mr Trump arrived.
Mr Trump was asked about the EU referendum result, which saw Leave beat Remain by 52% to 48%, shortly after he touched down at Turnberry in a helicopter.
The US billionaire answered: said: "I think it's a great thing that's happened. It's an amazing vote, very historic.
"People are angry all over the world. They're angry over borders, they're angry over people coming into the country and taking over and nobody even knows who they are.
"They're angry about many, many things in the UK, the US and many other places. This will not be the last."
Mr Trump said UK divisions "will heal" as "it is a great place", adding: "I said this was going to happen and I think it is a great thing.
"Basically, they took back their country. That's a great thing.
"I think we're doing very well in the United States also, and it is essentially the same thing that is happening in the United States.
"I want to support my son who really represented me here in building this great great place (Turnberry)."
When asked his opinion on David Cameron announcing he is to step down as prime minister after the Leave vote, Mr Trump said: "Well, that's too bad."
Donald Trump is not generally regarded as a shy, modest man.
So few were surprised that despite arriving at his newly reopened Ayrshire golf course just minutes after the prime minister announced he was stepping down, Mr Trump had an eye on landing some headlines of his own.
The presidential hopeful swept off the helicopter with his name written down the side of it, at Turnberry, the golf course he has also appended his name to, and proclaimed that he had predicted the whole Brexit thing ages ago.
And in any case, it was great news - especially for anyone hoping to harness a similar anti-establishment wave in, say, a White House bid.
Mr Trump's words carry some weight, given that shortly after Mr Cameron leaves Downing Street, he could be moving in to the Oval Office.
And the massive, multinational press pack which greeted him at Turnberry even on this rather busy news day will have done nothing to dent his self-confidence.
Despite the characteristically chaotic approach - the carefully planned itinerary was changed twice, only for Mr Trump to turn up more than half an hour late to both events anyway, before he called for "ONE more question" at least a dozen times at the press conference - the media were tightly controlled throughout the event.
First we were scanned with metal detectors, then ferried to the hotel (all of 200m away) on a series of buses.
The buses were on hand again to take us just down the road to the golf course, the route keeping the media a safe distance from the handful of protesters who had gathered - just 43 of them, Mr Trump said, with a mild air of disappointment.
But then, that's life for a big-hitting presidential candidate, he assured us.
"Half of the people love you, the other half hate you," he said. "That's politics."
Speaking at a news conference, Mr Trump acknowledged his family connection with Scotland through his mother Mary MacLeod, who was born in Stornoway in the Outer Hebrides.
"She loved Scotland, she would be here a lot," he said.
"She would come every year with my sister Mary and my sister Elizabeth and they just loved it. Her loyalty to Scotland was incredible."
The billionaire said his mother would often visit Turnberry for dinner with friends but she never played golf.
He said it was "an honour" to have taken ownership of the resort, which he acquired from Dubai-based Leisurecorp two years ago, before adding his name to the brand.
Mr Trump owns more than a dozen golf resorts in the US and opened his first in the UK, at the Menie estate in Aberdeenshire, in 2012 after controversy surrounding planning, environmental issues and clashes with local people who refused to move.
In perhaps a veiled reference to those past difficulties, he praised the local politicians in Ayrshire for working with him to approve the refurbishment plans for Turnberry.
"The local politicians, and all of the politicians all throughout have been absolutely incredible," he said, adding: "They have approved virtually everything that we asked for."
Mr Trump also praised the Royal and Ancient, the ruling body in golf outside north America, for working closely while changes were made to the resort's Open course.
Turnberry is one of 10 UK golf courses to host the Open golf championship on a rotational basis.
The tournament has been played there on four occasions, most recently in 2009.
The Open is expected to be played in England in 2020 and at St Andrews in 2021, meaning the earliest it could return to Turnberry would be 2022.
Mr Trump's news conference was interrupted comedian Simon Brodkin, also known as Lee Nelson, who attempted to hand out golf balls with a swastika on them. He was escorted away by security officials.
That incident, and the protest outside Turnberry, appear to have been motivated by controversial comments from the outspoken billionaire during his campaign for the Republican presidential nomination.
Most notable among these was his call for a temporary ban on Muslims entering the US following the San Bernardino shootings in California.
This prompted a petition advocating a ban on Mr Trump coming to the UK, which attracted hundreds of thousands of signatures. This in turn triggered a debate at a Westminster committee room, which ended without a vote being taken.
Mr Trump's comments on Muslims were described as "divisive, unhelpful and quite simply wrong" by Prime Minister David Cameron and "repugnant and offensive" by Scotland's First Minister Nicola Sturgeon.
Earlier this week, two local residents began flying Mexican flags on properties surrounding Mr Trump's other Scottish golf course in Aberdeenshire.
They said they wanted to "show solidarity" with the people of Mexico after Mr Trump outlined plans to build a wall along the US-Mexico border to stop illegal immigrants.
Before Mr Trump arrived, Keir McKechnie, spokesman for Stand Up to Racism Scotland, said: "His message of hate is one that we'll challenge and we would not encourage anyone to support him in his presidency.
"We want to represent people across the whole of the UK and beyond who reject Trump's racism and Islamophobia."


The Western Mail is to get its first female editor.

Trinity Mirror has confirmed Catrin Pascoe, currently editor of the South Wales Echo, will take up the post on 1 March.
Alan Edmunds, currently the newspaper's editor and editor-in-chief at Media Wales, is to become deputy editorial director for Trinity Mirror Regionals.
The daily newspaper was founded in Cardiff in 1869.


A man with motor neurone disease has scooped a US prize for inventing a device which allows people to control wheelchairs using only their eyes.

The Eyedrivomatic developed by Patrick Joyce, from Wells, Somerset, allows quadriplegic wheelchair users to steer, recline and change speed.
His wife woke him at 0400 GMT to tell him he had won the top Hackaday prize of $196,000 (Â£128,000).
Mr Joyce, 46, was diagnosed with motor neurone disease in 2008.
Mr Joyce has spent two years developing the device, alongside his "test pilot" Steve Evans from Thames Ditton in Surrey.
It links existing Eyegaze software, used to control computers using eye movements, to a joystick on the controls of powered wheelchairs - it is attached to the control pad using "non invasive" velcro, so can be used on loaned wheelchairs.
Mr Joyce, who is terminally ill, can still control his wheelchair himself, but Mr Evans can only move his eyes.
As well as using the Eyedrivomatic to move around, Mr Evans has also successfully attached it to a Nerf gun to fire foam darts at his children.
Mr Joyce said: "I was gobsmacked that we won... The money comes at an opportune moment as our house is too small and we couldn't afford to move. I wasn't supposed to live as long as I have and we hadn't planned on me still being alive when our kids were teenagers."
He added: "I doubt Eyedrivomatic will be commercially developed. There are liability issues that would probably prevent it happening. But ... I designed it to be easy to build at home."


Northern Ireland manager Michael O'Neill was pleased to come away with a scoreless draw in the opening World Cup qualifier against the Czech Republic.

Media playback is not supported on this device
The hosts dominated in a dour game as Northern Ireland played their first match since the Euro 2016 finals.
"I'm happy with a point - we showed great spirit when they put us under pressure in the second half," he said.
"The first half was good and we broke on the counter-attack but our final ball or run was disappointing."
Northern Ireland rarely threatened in a disjointed and sluggish display and only poor finishing from the Czechs saw O'Neill's side make an unbeaten start in Group C.
O'Neill is on course to achieve an early points target but he is concerned that some of his players are missing out on first-team club action.
"We said at the outset that we want seven points from our first four qualifiers," O'Neill told Sky Sports.
"This sets us on our way and we have to win our home games against San Marino and Azerbaijan.
"It showed in the second half that three or four players have not been playing club football.
"It would be great if we had players who were playing on a regular basis."
This group includes Norwich City striker Kyle Lafferty, who struggled to make an impact and was substituted before the hour mark.
Jonny Evans was Northern Ireland's top performer in Prague, with the West Brom defender a formidable barrier against the Czechs.
"I'm satisfied to get a draw from the game - they had a lot of pressure near the end and we battled hard to keep a clean sheet," said Evans.
"You could see the effort we put in throughout the side and it's always important to take something from the opening game."


Google has delayed its plans to trial its modular smartphone concept, codenamed Project Ara.

The first Project Ara hardware was due to be trialled in Puerto Rico this year, but has been pushed back to at least 2016.
The trial will take place in a new location in the US, the Project Ara team said via a series of tweets.
The team blamed "lots of iterations" in the design, which was first shown off in 2013, for the delay.
Project Ara is Google's intriguing attempt at creating a smartphone that comes in bits.
It means certain components can be added or taken away without the need for intricate alterations to the phone.
It would potentially mean smashed screens or worn batteries would be less costly to replace - as well as allowing others to create bespoke hardware for specific tasks.
Google had planned to offer around 20 to 30 different modules for the Puerto Rico trial.
In a series of tweets, the team told followers that "#Project Ara isn't going anywhere", but said it had been set back by "Lots of iterationsâ€¦ more than we thought".
The first public demonstration of the technology, at Google's I/O developers conference in May, was well-received.
Writing on a forum for developers interested in working on Project Ara, San Francisco based designer Garrett Kinsman said he felt a "sense of overwhelming sadness" at the delay.

UK internet service providers have been asked to block access to dozens of URLs that are suspected of linking to pirated content.

Content providers regularly update the lists of sites they want blocked and the latest one includes popular file-sharing index Demonoid.
The list was started in 2012 when ISPs were forced to block access to the Pirate Bay.
At least 23 new URLs are on the latest list being sent to the main UK ISPs.
Content providers must apply for a court order to block individual sites such as Pirate Bay but, after that, they can add URLs that link to that particular site without any formal order.
The sites they choose link to pirated software including music, films, TV shows and e-books.
Content providers say that they carefully target sites whose sole purpose is to make money from other people's content.
In response to the latest requests, BT told the BBC: "BT will only block access to websites engaged in copyright or trademark infringement when ordered by a court to do so.  The list of websites that BT has been ordered to block access to can be found here."
The list includes content from the Football Association, the Motion Picture Association of America and even some watchmakers - such as Cartier and Montblanc - who have requested that counterfeit sites be shut down.
But by far the largest number of requests comes from members of the BPI, which represents UK music labels.
"The recent expansions show that copyright holders remain concerned about people circumventing blockades, which is a common practice among users," said Ernesto Van der Sar, editor of technology news website TorrentFreak.
"New unblocking opportunities continue to appear so this is the only way to ensure that the efficacy of existing court orders isn't further diminished. It's a never-ending game of whack-a-mole."
How effective such blocks are remains open to debate.
A study conducted in May, by US universities Carnegie Mellon and Wellesley College, found that blocking the Pirate Bay had little impact on the rise in legal channels - instead people just turned to other piracy sites, Pirate Bay mirror sites or virtual private networks that allowed them to circumvent the block.
But, on the other hand, researchers found that bulk blocking - where multiple sites are shut down - was much more effective. Following such blocks in 2013, use of legitimate sites such as Netflix rose by around 12%, they found.


Two people have been charged with manslaughter after a woman died while bungee jumping in Spain.

Kleyo De Abreu, 23, from London, was killed on 21 July in Lanjaron, Granada, while jumping from the Tablate Bridge.
The Guardia Civil has charged the owner of an adventure company and a bungee jump supervisor with her death.
Its investigation found there was miscommunication between the supervisor and Miss De Abreu, who jumped before the equipment had been made safe.
One supervisor had been left to monitor 14 people taking part in the bungee jump, which was "not enough" to guarantee customer safety, police found.
It said the monitor's role was to secure the ropes and harness before authorising the person to jump.
But after attaching the harness to Ms De Abreu and moving away to tighten the ropes, there was believed to have been a "lack of communication or understanding" and Ms De Abreu jumped before being told to do so.
The police report stated: "This jump, performed before the ropes were properly tensioned...could be the cause of the accident".
Investigators believed the monitor "did not execute their function with due care and precautions", the report said.
There are two bridges at the site - a modern bridge from which bungee jumps are launched, with an ancient Roman bridge underneath.
It is believed Ms De Abreu hit the lower bridge, causing fatal injuries, when she jumped from above.
Her father Bernard Atwell described his daughter as "sweet, caring, bubbly and focused".
Ms De Abreu, an aspiring fashion student from Brixton, had been visiting her aunt in Spain, who was watching when she fell.


With the wrong film being mistakenly named best picture at the Oscars - La La Land instead of Moonlight - lots of people are asking how this could have happened.

Two people count the votes and know the winners in advance. Each has a full set of envelopes containing cards with the winners' names - just in case something happens to the other set.
Those people - from accountancy firm PwC - stand on either side of the Oscars stage and hand the envelopes to the award presenters just before they step on stage.
So after Emma Stone won best actress, the other best actress envelope was handed to Warren Beatty - who was presenting the best picture prize - by mistake.
That explains why a confused Stone told reporters afterwards: "I was holding my best actress in a leading role card that entire time."
It looked like the veteran actor was fooling around when he opened the envelope, looked at the card, then looked inside the envelope again to see if there was another card inside.
He checked again, then showed the envelope to his co-presenter Faye Dunaway. She read the words: "La La Land."
Beatty explained: "I want to tell you what happened. I opened the envelope, and it said Emma Stone, La La Land. That's why I took such a long look at Faye, and at you [the audience], I wasn't trying to be funny."
Oscars host Jimmy Kimmel said afterwards: "He was confused because the card, which he showed to me by the way, said 'Emma Stone, La La Land' on it.
"So this was confusing obviously, we thought he was being coy and cute to make everybody suffer but in reality he was perplexed by why her name was on it."
With the La La Land acceptance speeches in full flow, the PwC people and other officials came on stage to inform the film's cast and creators - and the world - that there had been a terrible mistake.
La La Land producer Fred Berger said: "We lost by the way, but you know."
Fellow producer Jordan Horowitz then said: "Guys, I'm sorry, no, there's a mistake. Moonlight, you guys won best picture."
And the third producer Marc Platt said: "This is not a joke I'm afraid they read the wrong thing."
Horowitz added: "This is not a joke, Moonlight has won best picture." He then held the card up to the audience to prove his point, reading from it: "Moonlight, best picture."
Cue bedlam.

UK pilot Tracey Curtis-Taylor has had to halt her bid to fly across the USA after her vintage biplane crashed in the Arizona desert.

The transcontinental flight from Seattle to Boston was part of her bid to circumnavigation the world in an open cockpit craft.
The 54-year-old adventurer, who calls herself "Bird in a Biplane", has already flown from the UK to Australia and Cape Town to Goodwood in her 1942 Boeing Stearman.
Ms Curtis-Taylor, born in Stamford in Lincolnshire, said she was "always interested" in flight because it is such a "fascinating thing".
Her first memories of aviation were of being taken to air shows by her journalist father while she was growing up in Canada.
The 1965 film Those Magnificent Men in their Flying Machine sparked her interest in the early years of flight.
Ms Curtis-Taylor is particularly inspired by pioneering female aviators such as Amy Johnson and Lady Mary Heath, recreating their flights from the UK to Australia and South Africa.
After she completed her trip to Australia, she described the flying as "sensational" and said the open cockpit biplane had given her an "insight" into what Ms Johnson went through.
"To fly something like this, low level, halfway around the world seeing all the most iconic landscapes, geology, vegetation - it's just the best view in the world," she added.
When she was asked about flying, Ms Curtis-Taylor, who is now based at Goodwood in West Sussex, replied: "You never want to stop, it is absolutely addictive, it is so thrilling and exciting."
1982 - drove from Johannesburg to London in a Bedford truck.
2007 - took park in the Peking to Paris vintage and classic car rally.
2013 - flew from Kiev to Cape Town in an Antonov 2 aircraft.
2013 - inspired by Lady Mary Heath's exploits, she flew from Cape Town to Goodwood in her 1942 Boeing Stearman Spirit of Artemis biplane.
2015 - in October she started her attempt to recreate Amy Johnson's flight from the UK to Australia.
2016 - landed in Sydney in January, completing the 14,600- nautical mile trip.
2016 - a crash in the Arizona desert halted her bid to fly across the USA.


Donegal's Ryan McHugh says he is "flying again" after recovering from injury for Sunday's Ulster SFC opener against Antrim at Ballybofey.

McHugh suffered an ankle tendon tear in Donegal's penultimate Football League match in late March but recently returned to action for his club Kilcar.
"I played in the club championship and got through it fine so I'm 100%," the 2016 All-Star told BBC Sport NI.
The roving McHugh was probably Donegal's best league performer.
Rory Gallagher's side comfortably retained their Division One status but a narrow closing defeat by Mayo meant that they missed out on a place in the league decider.
With Antrim suffering relegation back to Division Four, Donegal will be overwhelming favourites at MacCumhaill Park but McHugh insists that the home team will not be underestimating the Saffrons, who claimed a shock Ulster Championship win at Ballybofey eight years ago.
"We'll certainly not be looking past Antrim. We'll not be getting ahead of ourselves," added the Kilcar man.
After the retirements of experienced campaigners such as Eamon McGee, Neil Gallagher, Colm McFadden, Rory Kavanagh, Christy Toye plus the decisions of Odhran MacNiallais, Leo McLoone and Anthony Thompson to opt out in 2017, many expected a season of transition and struggle for Donegal.
However, instead Donegal appeared to be invigorated by the arrival of young talents such as Jason McGee, Michael Langan, Ciaran Gillespie, Eoghan Ban Gallagher and Jamie Brennan during the league campaign.
The youngsters had all achieved underage successes with the county and McHugh says their "winning mentality" has boosted the squad.
"They have won at under-21s and minors with Donegal and they are just great young lads who know what it takes to win.
"There were a lot of changes in the squad but the lads who have come in have been a complete breath of fresh air.
"They are extremely talented lads but they also work hard. They have done everything that has been asked of them and are really stepping up for Donegal."


The warm, turquoise sea glimmers tantalisingly as it laps at sandy beaches surrounded by palm trees and colourful, exotic flowers.

Ordinarily in November, few sun loungers would be unoccupied under the umbrellas that line the shores of Sharm el-Sheikh.
Most would be filled with Russian and British holidaymakers escaping the cold weather at home.
But now most tourists have disappeared.
"The beach is empty.  It was full until a few days ago but the Russians have all gone," says Richard Bourne from Wales, who is here sunbathing with his wife.
"I feel so sorry for the people," he goes on.  "I don't know how the hotels will survive the coming weeks."
Not far away, the bars and clubs of Naama Bay pump out loud music to ever-diminishing numbers of customers.  Souvenir sellers and diving tutors sit idle with worried expressions.
"There's no business," bemoans Raed, who runs a store selling Pharaonic knick-knacks - from plastic scarabs to papyrus scrolls - that are usually popular with European visitors.
The resort is increasingly deserted after the plane crash which led the UK, Russia and several other countries to suspend flights here.
All 224 people onboard a Russian charter jet were killed when it came down over the north of the rugged Sinai peninsula on 31 October.
Suspicions that a bomb could have been planted onboard have raised concerns about security at Sharm el-Sheikh airport.
In recent days, airlines have made special arrangements to fly out tens of thousands of passengers - without bringing in new arrivals.
"On a normal basis we would be 90% full right now, everyone would be working and everyone would be happy," says Amr Darwish, an owner of the Terrazzina beach club.
He worries he might have to lay off staff in the near future.
"We don't know when the tourists are going to be able to come back. You can't make a business plan for next week, let alone next month or next year," he adds.
According to the tourism ministry, Egypt stands to lose 2.2bn Egyptian pounds ($280m) a month after the cancellation of flights from Russia and Britain.
Two-thirds of tourists to Sharm el-Sheikh come from these two countries.  The destination earns about a third of Egypt's total proceeds from tourism.
It was able to recover from previous shocks, including a series of deadly militant bombings along the Red Sea coast between 2004 and 2006 and a killer shark attack.
In the political turmoil since the 2011 uprising, which overthrew the long-time leader, President Hosni Mubarak, the resort has proven resilient compared to other popular attractions like the Giza Pyramids and Luxor.
Yet with the Egyptian economy still in a fragile state, the effects of the latest setback will be deeply felt.
Workers in Sharm el-Sheikh - from taxi drivers to hotel receptionists - come from across the country and send salaries home.  Tourism is a vital source of foreign currency.
"This couldn't have come at a worst time," says Angus Blair of the Signet Institute, a Cairo-based economic think-tank.
"Egypt needs this [resort] economically in terms of employment and foreign exchange revenues.
"It will definitely damage sentiment and lead to problems at the central bank because clearly they're already under stress trying to access foreign currency for trade."
This week a senior Russian official warned it would take "several months, as a minimum" for Russian flights to Sharm el-Sheikh to resume as the investigation into what caused the crash continues.
He said it would be impossible to radically revise Egypt's security system quickly.
Concerns have been raised about baggage scanning procedures and searches at an entry gate for food and fuel for aircraft at Sharm el-Sheikh airport.
There are some hopes that in the short-term, Arab tourists and those from central Europe can be attracted to the resort in greater numbers.
However most business owners accept the reality is that they must brace themselves for another tough period ahead.
"It will take us time to recover but a place like this never dies," says Mr Darwish. "It's a nice resort with great weather. We have the sea, the corals, the desert. It's magical."
The Bournes, visiting from Wales, also believe in the enduring appeal of Sharm el-Sheikh - even though their holiday has been overshadowed by the plane crash which happened a day after they arrived. Their return home has been delayed by at least a day.
"This could happen anywhere, couldn't it?" Jenny Bourne comments stoically.
"I would come back again next year," her husband, Richard, says.  "They just need to sort that airport out."
Egypt is counting on other tourists adopting a similar attitude.


A man who confronted police while armed with a 29,000-volt stun gun in Fife has been jailed for five years and three months.

John Wishart 39, fired the weapon towards one officer as another hid behind a car for safety outside a bar in Leven.
CS spray was used to try and stop Wishart, who at one point jumped into the driver's seat of the police car.
He was eventually detained by the officers. The incident happened in May.
Wishart pled guilty to four charges - including assault and possessing the stun gun - at the High Court in Glasgow.
After being arrested, police also discovered Wishart was in possession of two knives.
Lord Boyd told Wishart: "Police officers who serve the community are entitled to the protection of the courts.
"You tried to threaten or intimidate them in a bid to prevent them carrying out their duty.
"I accept you did not intend to do any harm with the Taser - you were intent on using it to escape from the police."


A warning about cold water shock and changeable conditions has been issued to Easter visitors to the seaside.

Lifeguards return to duty at seven locations this weekend, with the RNLI giving safety advice.
Despite warmer weather, supervisor Rob Steele said water temperatures are cold and swimmers should wear wetsuits.
Lifeguards will again be at Three Cliffs Bay, Gower, after a campaign led to their installation in 2016 when two people drowned 12 months earlier.
They will also be on patrol at Tenby South Beach and Whitesands, Pembrokeshire, Aberavon in Port Talbot, Coney Beach and Trecco Bay, Bridgend county and Whitmore Bay, Vale of Glamorgan.
In total, the RNLI will patrol 38 Welsh beaches over the course of the summer in 2017.
Mr Steele added: "Conditions can also be changeable so please bring appropriate clothing and be ready for all weathers and if you see someone in trouble in the water, don't attempt to rescue them yourself, as you could also be putting yourself in more danger."
In 2016, the RNLI responded to 1,271 incidents and rescued or assisted 1,436 people in Wales.


A US submarine has arrived in South Korea, amid worries of another North Korean missile or nuclear test.

The missile-armed USS Michigan is set to join an incoming group of warships led by aircraft carrier Carl Vinson.
North Korea is celebrating its army's 85th founding anniversary on Tuesday. It marked the event with a large-scale firing drill, South Korea said.
Tensions have risen in the area in recent weeks, with the US and North Korea exchanging heated rhetoric.
Experts fear Pyongyang could be planning more tests - it has marked some key anniversaries in the past with nuclear tests or missile launches.
However, South Korea's defence ministry said "no unusual development had been detected".
Instead, the North conducted a large live-fire drill around the city of Wonsan, South Korea said.
"Our military is closely monitoring the North Korean military's movement," the Office of the Joint Chiefs of Staff said.
North Korea conducted a failed ballistic missile test on 16 April, prompting US Vice-President Mike Pence to warn it not to "test" President Donald Trump.
In an unusual move, the entire US Senate has been asked to attend a briefing on North Korea on Wednesday at the White House.
The USS Michigan docked at South Korea's Busan port on Tuesday, in what it called a routine visit. It is a nuclear-powered submarine carrying 154 Tomahawk cruise missiles and 60 special operations troops and mini-subs, reported the South Korean newspaper Chosun Ilbo.
Analysis: Stephen Evans, BBC News, Seoul
The North Korean crisis is moving on many fronts.
The US submarine docking in South Korea is a routine event - but in this time of heightened tension it has extra significance
Pyongyang remains defiant, including of China, warning that if it helped the US, the results would be "catastrophic".
Envoys from South Korea, the US and Japan are discussing North Korea in Tokyo.
What this all adds up to depends on whether President Trump has rejected the advice given to his predecessors that attacking North Korea could provoke an attack on Seoul, with one expert saying there could be tens of thousands of deaths on the first day.
It may be that President Trump has decided that the cost of North Korea eventually getting nuclear weapons that could strike the US means that the risk of war has to be taken. We simply do not know.
The submarine is expected to take part in military exercises with the Carl Vinson warship group, which the US said it was dispatching to North Korea earlier this month to "maintain readiness" in the region.
At the time, Mr Trump said that he was sending an "armada" to the region and that the US had submarines which were "very powerful, far more powerful than the aircraft carrier".
Pyongyang reacted angrily to the aircraft carrier deployment, threatening to sink it and launch a "super-mighty pre-emptive strike" against what it called US aggression.
However, the US warships caused some confusion and attracted mockery when it emerged that they actually sailed in the opposite direction, away from North Korea, after the announcement. However, US Navy officials said they are now proceeding to the region as ordered.
China is North Korea's only ally and main trading partner - and the US has been urging Beijing to help put pressure on Pyongyang.
Chinese President Xi Jinping spoke to Mr Trump on Monday, urging all sides to "maintain restraint and avoid actions that would increase tensions".


Scottish First Minister Nicola Sturgeon has said everybody who tried to predict the price of oil had got it wrong.

Her comments came after new forecasts wiped £9.6bn off expected North Sea revenues over the next five years.
Ms Sturgeon said the Scottish and UK governments as well as the Office for Budget Responsibility had put prices at between $100-120 a barrel.
Her comments came after big changes to the North Sea tax regime were announced, to support the sector.
The industry was hit after the price of Brent crude oil dipped below $50 a barrel, after having been at about $110 between 2010 until mid-2014.
'Bad news'
During first minister's questions at Holyrood, deputy Scottish Labour leader Kezia Dugdale  said the latest oil projections had exposed "dodgy sums" at the heart of the SNP's UK election strategy and plans for "full fiscal autonomy".
The Office for Budget Responsibility (OBR), set up to provide independent analysis, has downgraded its projections for oil receipts in 2016-17 from £2.4bn in December to £600m, with its forecasts for each of the five years to 2019-20 now less than £1bn.
Ms Sturgeon said: "When the Scottish government was projecting an oil price of $110 a barrel, the OBR was projecting an oil price of $100 a barrel and the UK's department of energy and climate change was projecting an oil price of upwards of $120 a barrel.
"So I think it's fair to say, everybody's projections about oil were wrong."
The first minister went on to accuse Labour of being prepared to "gleefully pounce on anything they can describe as bad news".
Wednesday's budget saw Chancellor George Osborne announce Petroleum Revenue Tax (PRT) would be cut from 50% to 35% to support continued production in older fields.
He added that the existing supplementary charge for oil companies would also be cut from 30% to 20%, backdated to January, effectively reversing the hike in the 2011 Budget.


Cilla Black died of a stroke after falling over at her Spanish home on Saturday, the coroner has confirmed.

The 72-year-old was sunbathing at her villa in Estepona when she stood up, lost her balance and fell hitting her head, which knocked her unconscious.
She subsequently died of a stroke, and would not have suffered.
The star's three sons released the information after receiving the "conclusive" results of the post-mortem examination from authorities in Spain.
They have now been given permission to return her body to the UK as soon as possible for her funeral.
"We are devastated by the sad loss of our mother, but have been deeply touched by all the kind messages of support from her friends, fans, the public and media," said Robert, Ben and Jack Willis in a statement.
"We would like to thank everyone, especially the people of Liverpool. The tributes and condolences have really helped us through these difficult times.
"The Spanish authorities have now told us we are able to bring Mum home, which we hope to do as quickly as possible.
"We would also like to thank all those involved for their assistance with this matter. We respectfully request for our continued privacy to grieve."
Details of a funeral will be released in due course.
Born Priscilla Maria Veronica White, the Liverpudlian first found fame as a singer in the 1960s, with a string of top 10 hits including Anyone Who Had a Heart and You're My World.
Her career focus shifted to television in 1968, when she was given her own BBC One primetime series, and she went on to host Blind Date and Surprise Surprise for ITV.
Tributes to the star poured in from the world of entertainment after news of her death was announced on Sunday.
Sir Paul McCartney called her "a lovely girl who infected everyone with her great spirit" while Sir Bruce Forsyth said she would be "sadly missed".
Sir Cliff Richard said he had been due to visit her at her house in Spain next week. "Her passing away is a particular shock because despite the aches and pains we all suffer, she was always so upbeat," he said.
Hundreds of fans queued up to sign a book of condolence at Liverpool's town hall on Monday.
Friends said Black's health had been failing in recent months. She suffered from arthritis and both her hearing and eyesight were faltering.
Former EastEnders star Barbara Windsor told the BBC: "I've seen her twice in the last few weeks, and as always she looked immaculate. That was the thing about Cilla, she always looked spot-on.
"But I knew she wasn't very well, she didn't seem well."
In one of her final interviews, conducted in June, Black said: "I don't even sing in the shower these days, never mind touring."
"I'm too old. I can't do it like I did," she told Canadian DJ Robbie Lane on the Zoomeradio's British Invasion Show.
"I know Paul McCartney still does it, but he's an old ham! I've paid my dues. I think I deserve a little bit of rest."
"I'm content with what I have done and what I have achieved."
Black also expressed astonishment when Lane informed her that Anyone Who Had A Heart had been the UK's biggest-selling single by a female artist in the 1960s.
"I'm 72 years of age and for all that time I didn't know," she said.
"Well, I never. I can die happy now," she added with a chuckle.


An ex-police protection officer for Tony Blair has been jailed after he swindled more than Â£50,000 in benefits.

Vaughan Dodds, 45, who used to work for Durham Police, claimed he was housebound but spent the money on holidays and his children's private school fees.
Dodds, of Spennymoor, had denied a string of dishonesty charges when he appeared at Teesside Crown Court.
But he was convicted of nine charges and jailed for two-and-a-half years.
Dodds was a PC with Durham Police from 1993 until 2007 when he was dismissed for conduct reasons, a force spokeswoman said.
From February to November 1998 he was a member of the armed protection team based at Mirabella, the constituency home of the then Prime Minister and Sedgefield MP Tony Blair.
The hearing heard how Dodds claimed he could not walk more than 10 metres because he had myalgic encephalopathy (ME), and that his wife Mandy was also ill and hypersensitive to sound.
But a jury heard that the couple had gym membership and enjoyed a number of family foreign holidays.
The father-of-two was accused of fraudulently claiming income support, council tax relief and disability living allowance between 2005 and 2009.
Filling out forms to claim money, Dodds said that even the sound of toilet tissue being ripped was distressing for his wife, the hearing heard.
He claimed he had difficulty making main meals for himself and needed help getting out of bed.
But the court saw film footage of the pair at the gym and pictures of them on holiday riding a camel.
Graham O'Sullivan, prosecuting, said: "The prosecution make no bones about it. We say this money was dishonestly obtained.
"We say it was used by Mr Dodds and his wife to fund a comfortable lifestyle - a lifestyle this couple could not otherwise have afforded."
Judge Graham Cook said that the case was made worse because Dodds was a serving officer who should have known the difference between right and wrong.
Nigel Soppitt, defending, said prison would be "bleak and stark" for the former officer.


The coastguard station at Brixham in Devon has closed as part of a shake-up of rescue services.

The station has co-ordinated search and rescue services between Exmouth and Dodman Point, Cornwall, since 1984.
The station, along with Solent in Hampshire and Portland in Dorset, is being replaced by a national rescue centre in Segensworth, Hampshire.
Twenty six staff and managers have lost their jobs in Brixham and the building will be sold.
The Maritime and Coastguard Agency (MCA) is closing a total of five coastguard stations.
The new national rescue centre will be run alongside nine other 24-hour centres around the UK.
The changes have been criticised by some workers, users and politicians but the MCA said people "won't notice any difference to the way search and rescue missions are responded to".
Peter Davies, who was manager at Brixham coastguard station and has taken up a new role at Segensworth, said: "This new state-of-the-art network will ensure that we are better prepared and will improve how we manage the workload.
"I'd also like to thank the staff at Brixham coastguard, who have served the community with the utmost professionalism over many years.
"I am pleased that some are staying with the coastguard and have relocated to roles elsewhere."


Scotland's population reached an all-time high of 5,327,700 in mid-2013, according to new official figures.

The figures, based on 2011 census data, showed a rise of 14,100 people compared to the previous year, said the National Records of Scotland statistics.
About 47,700 people came to Scotland from England, Wales and Northern Ireland, according to the figures.
And about 39,800 left Scotland to go in the opposite direction, resulting in a net migration gain of 7,900.
National Records of Scotland chief executive Tim Ellis, said: "Scotland's population increased by 14,100 from mid-2012 to mid-2013, primarily because of a net in-flow of approximately 10,000 more people coming to Scotland than leaving, although there were also around 900 more births than deaths.
"For the 10th consecutive year, more people arrived in Scotland from the rest of the UK and overseas than left to go in the opposite direction.
"However, for the first time in nine years, net migration from the rest of the UK was larger than that from overseas."
Mr Ellis added: "More people arrived in Scotland from the rest of UK and fewer people left to go in the opposite direction, compared with the previous year.
"In contrast, for the third consecutive year, fewer people came to Scotland from overseas than in the preceding year."
The figures also said:


Summer spending can push people into financial trouble for the rest of the year so now is a good time to check the budget, an expert says.

A further £27m for the refurbishment of the Burrell Collection has been approved by Glasgow City Council.

The museum closed last October to allow work to upgrade the building and provide more display space.
About half of the project's £66m cost is being funded by the council.
In April 2015, the council provided £5.7m to kick-start the building's revamp, which houses treasures donated to the city by collector Sir William Burrell in 1944.
The Burrell collection consists of more than 8,000 artefacts but fewer than a fifth of them have been on show at any one time.
When it re-opens to visitors in 2020, the basement of the building will become part of the exhibition space, so that 90% of the objects can be viewed by the public.
The Heritage Lottery Fund has given £15m to the project and the UK government has also contributed £5m.
It is hoped a fundraising campaign will raise the rest.
Cllr Archie Graham said: "Sir William's great legacy has been described as the greatest gift a city has ever received and we have a moral duty to ensure it is housed in the finest of buildings."


Three UK teachers have made the final 50 in a competition to find the world's best teacher, with the winner to receive a prize of $1m (£670,000).

Teachers from London, Devon and the Vale of Glamorgan have reached the next stage of the Global Teacher Prize.
Last year's winner, Nancie Atwell from the United States, donated her prize money to her school.
Prime Minister David Cameron praised the UK teachers for the "tremendous achievement in being shortlisted".
The Global Teacher Prize, which will be awarded next March, was set up by the Varkey Foundation, the charitable arm of the Gems international education firm.
The three UK teachers are:
Colin Hegarty is already a classroom prize-winner, having won last year in the UK's Pearson Teaching Awards or so-called "Platos".
He was labelled a "maths superstar" for his work in school.
Mr Hegarty initially worked for finance firm Deloitte, after getting a first class degree in maths at Oxford University. Mr Hegarty took a £40,000 pay cut to become a teacher and has set up a free website to help with maths.
Janet Hayward, a primary school head teacher, has promoted the use of technology and is chairwoman of the National Digital Learning Council in Wales. Last year, she was made an OBE for services to education.
Sean Bellamy runs an unconventional secondary school based on principles of "democratic education", where rules are decided collectively, there is no uniform, staff are paid the same, and everyone is on first-name terms.
He is now being consulted by South Korea's education ministry and South Korean academics interested in ideas about "emotional intelligence" and young people's mental health.
The aim of the competition is to raise the status of the teaching profession by focusing on the achievements of exceptional teachers.
Last year, there was one UK teacher in the final top 10, Richard Spencer from Middlesbrough, who took part in a glitzy final ceremony, with former US president Bill Clinton.
David Cameron said the teachers' prize was a "fantastic initiative" and sent his congratulations to the UK entrants.
Ban Ki-moon, secretary-general of the United Nations, is also supporting the project: "I count my teachers as among the most influential people in my life."


What began as a peaceful uprising against Syria's President Bashar al-Assad five years ago became a full-scale civil war that has left more than 300,000 people dead, devastated the country and drawn in global powers.

Long before the conflict began, many Syrians complained about high unemployment, widespread corruption, a lack of political freedom and state repression under President Bashar al-Assad, who succeeded his father, Hafez, in 2000.
In March 2011, pro-democracy demonstrations inspired by the Arab Spring erupted in the southern city of Deraa. The government's use of deadly force to crush the dissent soon triggered nationwide protests demanding the president's resignation.
As the unrest spread, the crackdown intensified. Opposition supporters began to take up arms, first to defend themselves and later to expel security forces from their local areas. Mr Assad vowed to crush "foreign-backed terrorism" and restore state control.
The violence rapidly escalated and the country descended into civil war as hundreds of rebel brigades were formed to battle government forces for control of the country.
In essence, it has become more than just a battle between those for or against Mr Assad.
A key factor has been the intervention of regional and world powers, including Iran, Russia, Saudi Arabia and the United States. Their military, financial and political support for the government and opposition has contributed directly to the intensification and continuation of the fighting, and turned Syria into a proxy battleground.
External powers have also been accused of fostering sectarianism in what was a broadly secular state, pitching the country's Sunni majority against the president's Shia Alawite sect. Such divisions have encouraged both sides to commit atrocities that have not only caused loss of life but also torn apart communities, hardened positions and dimmed hopes for a political settlement.
Jihadist groups have also seized on the divisions, and their rise has added a further dimension to the war. Jabhat Fateh al-Sham, which was known as al-Nusra Front until it announced it was breaking off formal ties with al-Qaeda in July 2016, is part of a powerful rebel alliance that controls much of the north-western province of Idlib.
Meanwhile, so-called Islamic State (IS), which controls large swathes of northern and eastern Syria, is battling government forces, rebel brigades and Kurdish groups, as well as facing air strikes by Russia and a US-led multinational coalition.
Thousands of Shia militiamen from Iran, Lebanon, Iraq, Afghanistan and Yemen say they are fighting alongside the Syrian army to protect holy sites.
Russia, for whom President Assad's survival is critical to maintaining its interests in Syria, launched an air campaign in September 2015 with the aim of "stabilising" the government after a series of defeats. Moscow stressed that it would target only "terrorists", but activists said its strikes mainly hit Western-backed rebel groups.
Six months later, having turned the tide of the war in his ally's favour, President Vladimir Putin ordered the "main part" of Russia's forces to withdraw, saying their mission had "on the whole" been accomplished. However, intense Russian air and missile strikes went on to play a major role in the government's siege of rebel-held eastern Aleppo, which fell in December 2016.
Shia power Iran is believed to be spending billions of dollars a year to bolster the Alawite-dominated government, providing military advisers and subsidised weapons, as well as lines of credit and oil transfers. It is also widely reported to have deployed hundreds of combat troops in Syria.
Mr Assad is Iran's closest Arab ally and Syria is the main transit point for Iranian weapons shipments to the Lebanese Shia Islamist movement Hezbollah, which has sent thousands of fighters to support government forces.
The US, which says President Assad is responsible for widespread atrocities and must step down, has provided only limited military assistance to "moderate" rebels, fearful that advanced weapons might end up in the hands of jihadists. Since September 2014, the US has conducted air strikes on IS in Syria, but it has not intentionally attacked government forces.
Sunni-ruled Saudi Arabia, which is seeking to counter the influence of its rival Iran, has been a major provider of military and financial assistance to the rebels, including those with Islamist ideologies.
Turkey is another staunch supporter of the rebels, but it has also sought to contain US-backed Kurdish Popular Protection Units (YPG) fighters who are battling IS in northern Syria, accusing the YPG of being an extension of the banned Turkish Kurdistan Workers' Party (PKK).
In August 2016, Turkish troops backed a rebel offensive to drive IS militants out of one of the last remaining stretches of the Syrian side of the border not controlled by the Kurds.
The UN says at least 250,000 people have been killed in the past five years. However, the organisation stopped updating its figures in August 2015. The Syrian Observatory for Human Rights, a UK-based monitoring group, put the death toll at 310,000 in December 2016, while a think-tank estimated in February 2016 that the conflict had caused 470,000 deaths, either directly or indirectly.
More than 4.8 million people - most of them women and children - have fled Syria. Neighbouring Lebanon, Jordan and Turkey have struggled to cope with one of the largest refugee exoduses in recent history.
About 10% of Syrian refugees have sought safety in Europe, sowing political divisions as countries argue over sharing the burden. A further 6.3 million people are internally displaced inside Syria.
The UN estimates it will need $3.4bn (Â£2.7bn) to help the 13.5 million people who will require some form of humanitarian assistance inside Syria in 2017. More than 7 million people are affected by food insecurity and 1.75 million children are out of school.
The warring parties have compounded the problems by refusing humanitarian agencies access to many of those in need. Some 4.9 million people live in besieged or hard-to-reach areas.
With neither side able to inflict a decisive defeat on the other, the international community long ago concluded that only a political solution could end the conflict. The UN Security Council has called for the implementation of the 2012 Geneva Communique, which envisages a transitional governing body with full executive powers "formed on the basis of mutual consent".
Peace talks in early 2014, known as Geneva II, broke down after only two rounds, with the UN blaming the Syrian government's refusal to discuss opposition demands.
A year later, the conflict with IS lent fresh impetus to the search for a political solution in Syria. The US and Russia persuaded representatives of the warring parties to attend "proximity talks" in Geneva in January 2016 to discuss a Security Council-endorsed road map for peace, including a ceasefire and a transitional period ending with elections.
The first round broke down while still in the "preparatory" phase, as government forces launched an offensive around Aleppo. The talks resumed in March 2016, after the US and Russia brokered a nationwide "cessation of hostilities". But they collapsed the following month as fighting intensified.
The fall of Aleppo means the government now controls Syria's four biggest cities. But large parts of the country are still held by other armed groups.
Rebel fighters and allied jihadists are estimated to control about 15% of Syrian territory, according to the Syrian Observatory for Human Rights.
US officials said in early December 2016 that there were 50,000 or more "moderate" rebels, concentrated in the north-western province of Idlib and the western Aleppo countryside.
Rebels also control smaller areas in the central province of Homs, the southern provinces of Deraa and Quneitra, and the eastern Ghouta agricultural belt outside Damascus.
Kurdish forces, who say they support neither the government nor the opposition, meanwhile control much of Syria's border with Turkey, as well as a large part of the country's north-east.
And although they have suffered extensive losses in the past two years, IS militants still hold large parts of central and northern Syria, including the city of Raqqa.


The young woman to whom Vincent Van Gogh gave his severed ear has been named as Gabrielle Berlatier.

The Art Newspaper tracked down the farmer's daughter's full name after a new book on the artist, published last week, referred to the woman.
The discovery of her name comes after it was suggested Van Gogh cut off his entire ear, rather than part of it.
Gabrielle was working as a maid in a brothel when she was given the strange gift, according to the new research.
Van Gogh is said to have handed over the ear to her with the words "keep this object carefully".
Author Bernadette Murphy referred to the woman in Van Gogh's Ear: The True Story, which was published last week.
She said she had promised the woman's descendants she would keep her surname a secret, until they gave her permission to reveal it.
Following the book's publication, The Art Newspaper followed up details in the book and found Gabrielle's name in the records of the Institut Pasteur in Paris, where she had been treated for rabies after being bitten by a dog.
Analysis - Will Gompertz, arts editor
The legend of Van Gogh's self mutilation is turning into an art historians "ear-gate". First it was just the lobe, now it appears the entire auditory protrusion was severed by the deranged painter.
The uncovering of Gabrielle as the unlucky recipient of Van Gogh's dismembered ear adds more than just a new chapter to the now legendary tale. It means an entirely new story can be started. A story that seeks to uncover to whom the artist was speaking during his ultra heightened state, and how that can inform our knowledge of him as a pioneering painter.
I've always felt the story as previously told was too neat, too self-serving to the image the world wants to conjure of Van Gogh. I think the truth, if it ever emerges, will be a great deal darker and sadder and, paradoxically, all the more illuminating for it.
Martin Bailey, who wrote The Art Newspaper story, said discovering the name solved "one of the mysteries involving Van Gogh".
The Van Gogh expert said: "I was very intrigued to see the book and that there were enough clues in it to enable me to track down the name.
"It was a name I knew, so it wasn't an entire surprise and it was more of a confirmation. But now we know the person, we can possibly find out more in future about the incident, who she was and Van Gogh's links to her."
The Art Newspaper also suggested Gabrielle may have worked as a cleaner at the Cafe de la Gare, run by two friends of Van Gogh, and where the artist had stayed for several months.
This, the article said, "raises the intriguing possibility that she was someone whom Van Gogh saw regularly".
Gabrielle's first name had been revealed in 1936 in an article quoting the policeman called to the brothel in Arles where Van Gogh sliced off his ear in 1888, but newspaper reports at the time called her Rachel, which may have been a nickname.
The painter cut off his ear after suffering a mental breakdown. He was found alive by police the next day and taken to hospital.
Van Gogh took his own life in 1890.

League One-bound MK Dons will sign midfielder Ed Upson on 1 July when his contract with Millwall expires.

The 26-year-old ex-Yeovil man has been a Lions player since 2014, but was one of seven to be released after the League One play-off final loss.
He made 39 appearances for Neil Harris' side last season and has signed a two-year deal at Stadium:MK.
Upson becomes Karl Robinson's first summer signing as he prepares for life back in the third tier.

Lee Hughes has been given his first job in management after agreeing to rejoin one of his ex-clubs, relegated National League North side Worcester City.

Smethwick-born Hughes, 40, will work as joint-manager with John Snape at City, who will be in the Southern League - the seventh tier of English football.
Hughes was a City player when he first expressed an interest in succeeding Carl Heeley when he left in February.
Having been passed over, he joined Midlands rivals AFC Telford United.
But, having helped Telford stay in National League North, he left on Wednesday to return to Worcester, with whom he will carry on playing.
A club statement said: "The Board are excited with this new venture.
"During his time at the club, Lee Hughes was an influential part of the team.
"His new role as joint-manager will allow him to continue playing football, while the club utilise his vast experience and knowledge to coach and develop players."
Snape was already in joint charge of City - with midfielder Danny Jackman - after the long-serving Heeley stood down on 8 February after 22 years with the club.
Former roofer Hughes started his career with Kidderminster Harriers before joining West Bromwich Albion, who he left for £5m when he signed for Coventry City in 2001.
He scored 203 league goals with seven different clubs and spent three years out of the game when he was sent to prison in August 2004 for causing death by dangerous driving.
After his release from prison in August 2007, he played at Oldham, Blackpool, Notts County and Port Vale.
He moved back to non-league football with Forest Green Rovers in January 2014, after which he returned to Kidderminster. After a brief stop at Ilkeston, Hughes joined Worcester in September 2015.
Most renowned for their FA Cup win over then Second Division side Liverpool in 1959, Worcester have a history as a healthily-supported non-league club.
They were founder members of the Alliance Premier League when English football went to a fifth division in 1979.
But they have since mostly operated at sixth-tier level - and financial problems forced them to sell their old St George's Lane home four years ago,
After three seasons sharing with Kidderminster Harriers at Aggborough, they have spent this season sharing Bromsgrove Rovers' home at Victoria Road.
But, while they await the next stage in their long-term battle to return to the city, they can look forward to several local derbies next season - against Redditch United, Stratford Town and promoted Hereford FC.


Footage from Michael Schumacher's helmet camera shows him going at the speed of "a very good skier" when he hit a rock and fell, investigators say.

Investigators probing the former F1 driver's accident said he was eight metres off-piste when he crashed.
Prosecutor Patrick Quincy said he could not as yet estimate the 45-year-old's speed but said it was "not an important element of the investigation".
Schumacher suffered a severe head injury in the 29 December accident.
He is currently in a medically induced coma at a clinic in Grenoble where doctors describe his condition as critical but stable.
Fans gathered outside the hospital on 3 January to mark the racing legend's 45th birthday.
Speaking at a news conference in the French city of Albertville, the investigating team said they had so far attended the scene of the accident in the resort of Meribel, spoken to witnesses and the medical team.
They have also reconstructed events leading up to the crash, examined the helmet and skis and viewed footage filmed on a camera attached to his helmet, they said.
Mr Quincy, who is heading the investigation team, refused to be drawn on Schumacher's speed at the time of the accident saying they needed to go through the two-minutes of footage "image by image".
But another investigator, Lt Col Benoit Vinneman said the video appeared to show "completely normal behaviour by a good skier on this terrain".
Schumacher had deliberately chosen to go off piste, an area between a red and blue piste that was clearly signposted, the investigators said.
He hit a rock that was 8m (26ft) from the piste, and landed 9m (30ft) away from the piste, they outlined.
"[Mr Schumacher] is evidently an extremely good skier, but one of his skis hit a rock that was sticking out... it caused him to fall and he hit his head on the rock," Mr Quincy said.
Stephane Bozon, one of the local policemen involved in the investigation, said the skis were in "perfect condition" and had not been the cause of the accident.
Mr Quincy stressed their investigation into Schumacher's accident was no different to that given to other skiing similar skiing accidents. He said they had investigated 50 such cases.
Schumacher's family have been by his bedside since the accident, and have appealed for privacy in recent days, asking journalists to leave the clinic where he is being treated.
Michael Schumacher won seven world championships and secured 91 race victories during his 19-year career.
He won two titles with Benetton, in 1994 and 1995, before switching to Ferrari in 1996 and going on to win five straight titles from 2000.


Bradford City strengthened their League One play-off position as James Hanson's second-half hat-trick helped dent Walsall's hopes of automatic promotion.

Midfielder Filipe Morais gave the Bantams the lead on 54 minutes.
Hanson then netted three times in 16 minutes to keep Bradford in fifth, five points clear of seventh-placed Gillingham with two matches remaining.
Walsall have a game in hand but trail Burton by six points, having slipped to fourth as Millwall won at Bury.
Walsall interim boss Jon Whitney told BBC WM 95.6:
"It was not good enough. I have asked the players to have a look at themselves.
"I want them to go home and ask themselves 'Did you really do enough to challenge Bradford City? Did you do enough to want to get promoted to the Championship? Were you willing to put your head on the line?
"Sometimes that is what you have to do in football. It's not always about playing pretty football.
"We have to match them physically and we didn't do it second half. We capitulated after the first goal."


Stewart Murdoch has signed for Dundee United the day after his contract was terminated a year early by Ross County.

The 26-year-old midfielder has signed "an initial one-year deal", with Ray McKinnon expressing delight at his first signing as manager at Tannadice.
"He is exactly the type of player we need going into this season," he said.
"Not only is he the right age and a good footballer, but he is a ball winner who is strong in the tackle and will protect our central defenders."
Murdoch had joined County last summer after his departure from Fleetwood Town.
But half of his 34 appearances came as a substitute and he followed fellow midfielder Rocco Quinn out of the Scottish Premiership club.
Murdoch, who began his career with Falkirk and had a loan spell with Northampton Town before joining Fleetwood in 2013, told United's website: "I'm delighted to be joining Dundee United - it was an easy decision to make.
"It's a massive club and I want to help them get back to the Premiership, where they should be."
Following United's relegation from the top flight, 13 players have exited Tannadice along with manager Mixu Paatelainen and his backroom staff.
While Murdoch and Quinn have exited County, manager Jim McIntyre has already recruited three defenders and a goalkeeper, Aaron McCarey from Wolves, this summer.
Christopher Routis has arrived from Bradford City, Kenny van der Weg from Breda and Erik Cikos from Slovan Bratislava.


The UK's stock market started the year in positive mood, closing at a record high on its first day of trade.

After closing at a record level of 7,142.83 on the final trading day of 2016, the FTSE 100 rose another 0.5% to close at 7,177.89.
"No January blues for equity markets as traders in London have returned to their desks in optimistic mood," said Neil Wilson at ETX Capital.
"The FTSE is still enjoying the momentum from last week's Santa rally."
Banks and financial companies were the strongest performers with stock broker Hargreaves Lansdown up 5% and the bank Barclays up 3.78%.
Changes to broker ratings were behind some of the day's biggest moves. Intercontinental Hotels Group rose 1.3% after Barclays raised its rating on the company to "overweight".
But shares in Halfords and Next were both hit by downgrades from Deutsche Bank. Halfords fell 5.6% after Deutsche cut its rating on the company to "sell" from "hold".
Next - which is due to release a trading update on Wednesday - fell 4.2% after Deutsche Bank downgraded its rating on the retailer to "hold" from "buy".
A stronger than expected survey of the UK's manufacturing sector boosted the pound. The latest Markit/CIPS purchasing managers' index for manufacturing suggested activity in the sector hit a two-and-a-half-year high last month.
The pound rose 0.2% against the euro to â‚¬1.1766, although against the dollar it slipped by 0.17% to $1.2256.


An aircraft accident investigation driven not by experts, but by a group of the bereaved and an amateur American sleuth who hankers for the truth.
As I write, eight people who lost loved ones on board missing Malaysian flight MH370, together with self-funded traveller and mystery solver Blaine Alan Gibson, are trawling remote beaches in Madagascar, finding what might be parts of the plane.
They've been there for a week and have come across a number of possible pieces so far.
Grace Subathirai Nathan's mother vanished without trace in March 2014. She was one of the 239 people aboard the routine Malaysian flight.
Grace has posted these photos on her Facebook page:
"NEW Piece of potential mh370 DEBRIS found on Riake Beach, Isle St Marie by one of our next of kin Jiang Hui two hours ago! First time a piece was found by one of us. Such mixed feelings now for all of us - pain, sadness, confusion, hope," she writes.
One of those pieces, or a combination of them, could eventually hold the key to unlock this mystery. So far it's the debris washed ashore and found by the public, not the huge underwater sea search, that has given us the best idea of what may have happened on board.
Parts of the wing flap system found on beaches have allowed investigators to surmise that the aircraft came down quickly and out of control, rather than in a gentle controlled glide.
When I spoke to Grace on the phone she told me about their incredible, unique trip.
"Only one local person had even heard of MH370. Some had probably never seen an airliner, but they all understood the pain of loss," she said.
They want locals to become their eyes and ears, looking out for possible plane debris long after the families have returned home.
"We've had brochures printed in English, French and Malagasy. It's a step-by-step guide to what to do. How to handle debris if you find out. To photograph it, and how to get it to the right people.
"It's laminated so fishermen can have it on board without it getting wet. The local tourist board also helped us make a video in Malagasy that we can show people. Some might not be able to read".
They've also recruited the local mayor, who will look after pieces in his office until they can be shipped to experts in Malaysia.
For months now, the families have been questioning why it's down to them, rather than Malaysian officials, to co-ordinate the beach search around the world.
Grace is in Madagascar with a group of relatives from Malaysia, China and France. None of them knew each other before the tragedy. Now they've formed a team that's determined to keep the hunt for clues alive.
The sea search is being wound up soon, so in a couple of months, they'll be the only people looking. The bits they are finding still need to be analysed by experts to see if they are from the missing airliner.
They're washing up thousands of miles from where investigators are convinced the aircraft came down, yet it makes sense when you know how the oceans work.
After months of experiments, scientists have shown that the currents and winds would have carried small, floating parts across the Indian Ocean, to the coasts of South Africa, Tanzania, Madagascar, Mozambique and Reunion Island.
The very places bits are turning up.
It's likely that thousands of clues are lying around undiscovered, because no one is looking for them. Some might be personal effects from passengers. Others might hold small clues to what happened. If it's fire damaged for example, that could point to an accident, not a deliberate act.
It's one the world's biggest mysteries, yet it's coming down to the loved ones, the bereaved, and an American who craves the truth, to keep this search alive.

England head coach Eddie Jones wants World Cup winner Jonny Wilkinson to be part of his coaching team after a chance meeting in a supermarket.

Wilkinson, whose playing career finished in 2014, has yet to agree to Jones' invitation.
It was Wilkinson's late drop-goal that helped England beat Jones' Australia in the final of the 2003 World Cup.
"We would like to get Jonny involved, but he's quite a private person. We are having chats about it," Jones said.
"I saw him down at Waitrose shopping with a beanie over his head. I had coffee with him," added Jones, who has appointed Steve Borthwick, a former England team-mate of Wilkinson's, and Paul Gustard as forwards and defence coach respectively.
Wilkinson won 91 England caps, is his country's leading points scorer and is one of just five men to score 1,000 points in international rugby union, with his total of 1,246 second only to New Zealand great Dan Carter.
"After we had coffee he went and did a kicking session, and he doesn't play any more," said Jones, who succeeded Stuart Lancaster following England's early exit from the 2015 World Cup.
The 55-year-old Australian also revealed that he picked up ideas from Bayern Munich manager Pep Guardiola when the pair met last November.
"Pep is a big rugby fan. He studied rugby and European handball to look at how you move the ball into space," said Jones.
"We talked about his philosophy and about how you move the football into space, because in rugby, once you get away from the set-piece, it's like football."

More than 700 families have yet to return to their homes one year after Storm Desmond hit parts of Cumbria.

Thousands of homes and businesses were flooded when record rainfall struck, causing landslides and river bank erosion and killing livestock.
Cumbria County Council said the recovery had cost approximately £500m.
The council's figures also show almost 200 businesses affected by flooding, many in Allerdale and Carlisle, are still not fully operational.

2015 floods 'most extreme on record'
Cumbria Community Foundation flood appeal, set up to help those affected, has had more than 5,000 applications for grants and has awarded almost £7m.
Chief executive Andy Beeforth said: "The appeal has been a success because of the generosity of people who gave money. We are really fortunate to live in such supportive communities.
"We know that more than 700 families are still not back home and that this does not reflect the full situation, as some people remained living in their flooded homes, some are underinsured and those that have returned home report still having to deal with many issues."
Storm Desmond, the third major storm to hit the county in a decade, brought record rainfall, with 341.4 mm (13.4 inches) falling at Honister Pass in Borrowdale in a 24-hour period.
A major incident was declared, with Carlisle being among the worst-affected areas - the Army was called in to help evacuate homes.
Pooley Bridge at Ullswater and the Fitz Footbridge in Keswick both collapsed.
John McGuire, who owns The Sun Inn pub in Pooley Bridge, said: "Once [Pooley Bridge] was back, people were very gracious and trade has been very good.
"Everybody gets a little nervous when it rains, but other than that I've had a great time."
More than 2,000 properties in Kendal were directly affected by flooding and in April it was announced it would be given £24m for flood defences.
Flimby, Seaton and Maryport had about 40mm of rain in just a few hours, with more than 100 homes hit.
Nicola Hine, from Flimby, who was flooded out with her 11-month-old daughter, said: "I'm absolutely petrified every time it rains."
Alan Lambert's home in Keswick was so badly damaged that it has proved more cost-effective to knock it down and start again.
Mr Lambert, who is renting a flat above a shop while construction work continues, said: "We are going to raise the height of our house by 90cm.
"It would probably be simpler just to move, but clearly property values have dropped and not many people want to buy a house on a floodplain and that has flooded three times in 10 years."
Tom Armstrong has been unable to return to his flooded Carlisle home because of a disputed insurance claim.
He said he had been forced to seek legal advice over the amount offered by his insurer, which had in turn delayed renovation work.
He said: "It's affecting my health. I know I'm drinking more than I used to. When you're not comfortable and you're not in your own home for a second Christmas it's not much fun.
"At the moment it's looking like I won't be back in my own home until next spring."
Hundreds of farmers are still waiting for emergency funding to restore agricultural land, the National Farmers Union (NFU) said.
An Environment Department (Defra) spokeswoman said: "The government has invested £300m in helping communities recover from last winter's floods - this includes almost £4.4m paid out to farmers to complete flood repairs."


Imagine an industry that generates higher profit margins than any other and is no stranger to multi-billion dollar fines for malpractice.

Throw in widespread accusations of collusion and over-charging, and banking no doubt springs to mind.
In fact, the industry described above is responsible for the development of medicines to save lives and alleviate suffering, not the generation of profit for its own sake.
Pharmaceutical companies have developed the vast majority of medicines known to humankind, but they have profited handsomely from doing so, and not always by legitimate means.
Last year, US giant Pfizer, the world's largest drug company by pharmaceutical revenue, made an eye-watering 42% profit margin. As one industry veteran understandably says: "I wouldn't be able to justify [those kinds of margins]."
Stripping out the one-off $10bn (£6.2bn) the company made from spinning off its animal health business leaves a margin of 24%, still pretty spectacular by any standard.
In the UK, for example, there was widespread anger when the industry regulator predicted energy companies' profit margins would grow from 4% to 8% this year.
Last year, five pharmaceutical companies made a profit margin of 20% or more - Pfizer, Hoffmann-La Roche, AbbVie, GlaxoSmithKline (GSK) and Eli Lilly.
With some drugs costing upwards of $100,000 for a full course, and with the cost of manufacturing just a tiny fraction of this, it's not hard to see why.
Last year, 100 leading oncologists from around the world wrote an open letter in the journal Blood calling for a reduction in the price of cancer drugs.
Dr Brian Druker, director of the Knight Cancer Institute and one of the signatories, has asked: "If you are making $3bn a year on [cancer drug] Gleevec, could you get by with $2bn? When do you cross the line from essential profits to profiteering?"
And it's not just cancer drugs - between April and June this year, drug company Gilead clocked sales of $3.5bn for its latest blockbuster hepatitis C drug Sovaldi.
Drug companies justify the high prices they charge by arguing that their research and development (R&D) costs are huge. On average, only three in 10 drugs launched are profitable, with one of those going on to be a blockbuster with $1bn-plus revenues a year. Many more do not even make it to market.
But as the table below shows, drug companies spend far more on marketing drugs - in some cases twice as much - than on developing them. And besides, profit margins take into account R&D costs.
The industry also argues that the wider value of the drug needs to be considered.
"Drugs do save money over the longer term," says Stephen Whitehead, chief executive of the Association of the British Pharmaceuticals Industry (ABPI).
"Take hepatitis C, a shocking virus that kills people and used to require a liver transplant. At £35,000 [to £70,000] for a 12-week course, 90% of people are now cured, will never need surgery or looking after, and can continue to support their families.
"The amount of money saved is huge."
True, but just because you can charge a high price for something does not necessarily mean you should, especially when it comes to health, critics such as Dr Druker might say. Shareholders, who big pharma companies ultimately have to answer to, would have little time for such an argument.
Big pharma companies also say they only have a limited time in which to make profits. Patents are generally awarded for 20 years, but 10-12 of those are typically spent developing the drug at a cost of about $1.5bn-$2.5bn.
This leaves eight to 10 years to make money before the formula can be taken up by generic drug companies, which sell the medicines for a fraction of the price.
Once this happens, sales fall by 90%-plus. As Joshua Owide, director of healthcare industry dynamics at research company GlobalData, explains, "Unlike other sectors, brand loyalty goes out the window when patents expire."
This is why pharma companies go to such extraordinary lengths to extend their patents - a process known as evergreening - employing "floors full of lawyers" for this express purpose, one industry insider says.
For a drug raking in $3bn a quarter, even a one-month extension can be worth huge sums of money.
New formulations, combining two existing drugs to give a wider use, and enantiomers - a mirror image of the same compound - are some of the legal ways to eke out patents. But some drug companies, including the UK's GSK, have been accused of more underhand tactics, such as paying generics to delay the release of their cheaper alternatives.
As the loss of sales at the big pharma companies far outweighs the revenue made by the generics, this can be an attractive arrangement for both parties.
But drug companies have been accused of, and admitted to, far worse.
Until recently, paying bribes to doctors to prescribe their drugs was commonplace at big pharmas, although the practice is now generally frowned upon and illegal in many places. GSK was fined $490m in China in September for bribery and has been accused of similar practices in Poland and the Middle East.
The rules on gifts, educational grants and sponsoring lectures, for example, are less clear cut, and these practices remain commonplace in the US.
Indeed a recent study found that doctors in the US receiving payments from pharma companies were twice as likely to prescribe their drugs.
This may well exacerbate the problem of overspending on drugs by governments. A recent study by Prescribing Analytics suggested that the UK's National Health Service could save up to £1bn a year by doctors switching from branded to equally effective generic versions of the drugs.
$3bn
Glaxo SmithKline, 2012, over promoting Paxil for depression to under-18s
$2.3bn
Pfizer, 2009, over misbranding painkiller Bextra
$2.2bn Johnson & Johnson, 2013, for promoting drugs not approved as safe
$1.5bn Abbott, 2012, over illegal promotion of antipsychotic drug Depakote
$1.42bn Eli Lilley, 2009, for wrongly promoting antipsychotic drug Zyprexa
$950m Merck, 2011, for illegally promoting painkiller Vioxx
This all may change when new rules in the US and UK will force doctors to disclose all gifts and payments made by the industry.
Drug companies have also been accused of colluding with chemists to overcharge for their medicines and of publishing trial data that highlight the positive at the expense of the negative.
They have also been found guilty of mis-branding and wrongly promoting various drugs, and have been fined billions as a result.
The rewards are so great, it would seem, that pharma companies have continually been prepared to push the boundaries of legality.
No wonder, then, that the World Health Organisation (WHO) has talked of the "inherent conflict" between the legitimate business goals of the drug companies and the medical and social needs of the wider public.
Indeed the Council of Europe is launching an investigation into "protecting patients and public health against the undue influence of the pharmaceutical industry".
It will look at "particular practices such as sponsoring health professionals by the industry... or recourse by public health institutions to the knowledge of highly specialised researchers on the pay-rolls of industry".
No matter what the outcome of such investigations, however, the pharmaceutical industry is facing fundamental change, as the traditional model of developing drugs breaks down due to rising costs and scientific advances.
The cosy world of big pharmaceuticals is under threat like never before.
This is the first in a two-part series on pharmaceutical companies. The second looks at how and why fundamental change will take place in the industry.


Borussia Dortmund scored their 17th goal in three games as they beat Wolfsburg to go top of the Bundesliga.

Dortmund, who beat Legia Warsaw and Darmstadt 6-0, took the lead when Raphael Guerreiro fired home before Pierre-Emerick Aubameyang made it 2-0 when his strike looped in.
Wolfsburg's Daniel Didavi pulled one back but Ousmane Dembele tapped in to restore the two-goal advantage.
Aubameyang slid home his second and Lukasz Piszczek headed in the fifth.
Dortmund have nine points after four games - along with two other teams with 100% records, Bayern Munich and Hertha Berlin, who face each other on Wednesday.
Eintracht Frankfurt moved up to fourth with their third win from four games - a 2-0 win at Ingolstadt.
Freiburg'sNils Petersen scored the winner against Hamburg, who suffered a third straight defeat which left them third from bottom. Freiburg are ninth.
Hoffenheim drew for a fourth successive league game with a 1-1 draw at Darmstadt. Croatia striker Andrej Kramaric's goal for Hoffenheim was cancelled out by Denys Oliinyk's effort in the 92nd minute.
Hoffenheim are eighth in the Bundesliga, with Darmstadt in 14th.


A storm is brewing in a small County Down coastal community over a plan to replace a traditional lighthouse beam with a new, cheaper lighting system.

St John's Point lighthouse at Killough dates back to 1839.  It was used as a marker on a test run for the Titanic.
The building is now maintained by the Commissioners of Irish Lights, which plans to replace the sweeping beam with a static light-emitting diode (LED).
However, conservationists have begun a campaign to keep the existing light on.
The campaigners have enlisted the support of the South Down MP, Margaret Ritchie, who has written to both British and Irish governments, asking them to intervene to save the traditional lamp.
It follows a "heated" meeting at the weekend, when campaigners invited representatives of the commission to County Down to witness the strength of local opposition to the planned upgrade.
Eileen Peters, from Killough Community Association, told the Down Recorder that the lighthouse beam is of "cultural and historical significance" for the village and the surrounding area.
"There are those who love to see the lighthouse beam shining out across the bay and it's our understanding that the LED light will not stretch as far out across the water and that rather than rotate, will flash on and off," Ms Peters told the paper.
The Commissioners of Irish Lights is a maritime safety organisation based in the Republic of Ireland but which has responsibility for lighthouses and other coastal infrastructure throughout the island of Ireland, north and south.
The commission's director of operations and navigation services, Capt Robert McCabe, said the planned LED replacement would improve safety and reduce maintenance costs at the site.
Capt McCabe travelled to County Down for the weekend meeting and said he acknowledged the concerns of the campaigners and would consider their views.
He said the commission was "fully committed to maximising the potential of our heritage and history at St Johns Point" but he told the BBC that the commission's top priority was to provide the "best aid to marine navigation".
He added that it was important to remove mercury from the lighthouse, because of the risk that exposure to the element poses to human health.
The existing lamp has a Fresnel lens - an early 19th century invention that projects a long-distance beam using a modest light source.
The huge lens is the height of two average living rooms and weighs six tonnes.  It rotates inside a mercury bath.
In a statement, Capt McCabe said the lens would not be removed from the lighthouse, but the replacement of "obsolete" filament lamps with an energy efficient LED light source would provide a "more reliable and better quality light".
"Environmentally it is also a far superior solution allowing the removal of mercury and gas oil from the station. Mercury, being a hazardous and poisonous substance, is being removed for health and safety reasons."
However, he campaigners said there has never been an incident of mercury poisoning at the site and argue that many lighthouses in parts of England have safely maintained their traditional lamps.
The area's MP said the Commissioners of Irish Lights were accountable to both the UK and Irish governments, due to their cross-border remit.
Therefore, Ms Ritchie has written to Prime Minister David Cameron, Irish Prime Minister (Taoiseach) Enda Kenny and the UK and Irish transport ministers this week, asking them to step in to preserve the existing light.
Sinn FÃ©in MLA Chris Hazzard, who helped to organise the campaign meeting in the nearby village of Ardglass last Saturday, said the residents' views must be taken into account.
He said many older members of the coastal community found the traditional sweeping beam "soothing" and reassuring, describing it as a source of "solace" in stormy weather.
Mr Hazzard said the commissioners removed the fog horn from St John's Point four years ago "without consultation" and the residents did not want the same fate to befall the traditional beam.
Capt McCabe agreed that heritage campaigners were not consulted about the fog horn, but said they did consult mariners, and added that fog horns were removed from all of their lighthouses in Ireland at the time.
The commissioner said the exiting light at St John's Point has a nominal visibility range of 24 miles, while the LED light has a shorter range of 18 miles, but said this was still well within safety limits.
He said the new light would be brighter and during power failures it could be backed up by a battery supply rather than a generator, cutting down on cost.
However, he said they were keen to try to find a solution that would meet the requests of both heritage campaigners and the requirement to modernise the lighthouse with the very latest navigation equipment.
Capt McCabe said two lighthouse keepers' cottages at St John's Point site were currently being renovated and added that the whole site has the potential to become a "top class tourist attraction" based around lighthouse history.
He added that commissioners would consider the campaigners' views carefully before applying for listed building consent to make changes to the lighthouse.
The lighthouse, which now stands about 130ft (40m) in height, has undergone many renovations since the Marquis of Downshire laid its foundation stone in 1839.
In 1875, the main light source was converted from oil to coal gas.  By 1908 it was powered by vaporised paraffin and it was eventually converted to electric in 1981.
1981 was also the year that live-in lighthouse keepers were withdrawn and the building became automated, with a part-time attendant taking charge of the station.


A UK parliamentary report has severely criticised the intervention by Britain and France that led to the overthrow of Libyan leader Muammar Gaddafi in 2011.

The foreign affairs committee accused the then PM David Cameron of lacking a coherent strategy for the air campaign.
It said the intervention had not been "informed by accurate intelligence", and that it led to the rise of so-called Islamic State in North Africa.
The UK government said it had been an international decision to intervene.
The action had been called for by the Arab League and authorised by the UN Security Council, the Foreign Office added.
An international coalition led by Britain and France launched a campaign of air and missile strikes against Muammar Gaddafi's forces in March 2011 after the regime threatened to attack the rebel-held city of Benghazi.
But after Gaddafi was toppled, Libya descended into violence, with rival governments and the formation of hundreds of militias, while so-called Islamic State, also known as Isil and Daesh, has gained a foothold.
The committee's key conclusions include:
Mr Cameron has defended his handling of the situation, telling MPs in January action was needed because Gaddafi "was bearing down on people in Benghazi and threatening to shoot his own people like rats".
But the foreign affairs committee said the government "failed to identify that the threat to civilians was overstated", adding that it "selectively took elements of Gaddafi's rhetoric at face value".
The government also failed to identify the "militant Islamist extremist element in the rebellion", the MPs said.
"The possibility that militant extremist groups would attempt to benefit from the rebellion should not have been the preserve of hindsight," the committee said, adding: "UK strategy was founded on erroneous assumptions and an incomplete understanding of the evidence."
This report is effectively Parliament's attempt at a Chilcot inquiry into the Libyan intervention, only quicker and shorter.
And the criticism is weighty: the government's poor intelligence about the threat to civilians in Benghazi, its lack of awareness of Islamist elements among the rebels, the policy drift from saving lives to getting rid of Gaddafi, and David Cameron's lack of strategy for what should happen next.
The subtext is that the lessons of Iraq were ignored.
Yet in truth the report also reveals the uncertainty among policymakers about military intervention, torn between avoiding another Srebrenica-style massacre when the West turned a blind eye to the killings of Muslims by Bosnian Serbs in 1995 and the need to avoid another Iraq-style intervention when Western countries got bogged down in an internal conflict.
What happened in Libya was a half and half policy, of intervention without occupation. And it is a model that did not work.
Crispin Blunt, chairman of the committee, told the BBC: "We were dragged along by a French enthusiasm to intervene, and the mission then moved from protecting people in Benghazi, who arguably were not at the kind of threat that was then being presented...
"Indeed, on the basis of the evidence we took, the threat to the people of Benghazi was grossly overstated."
The committee said "political options" were available once Benghazi had been secured - including through ex-PM Tony Blair's contacts with Gaddafi - but the UK government "focused exclusively on military intervention".
February 2011 - Violent protests break out in Benghazi and spread to other cities. This leads to civil war, foreign intervention and eventually the ousting and killing of Gaddafi in August.
March 2011 - UK parliament approves British participation for military intervention alongside a coalition of nations, including France and the US.
2014 - Militants from so-called Islamic State claim responsibility for several attacks in Libya towards to the end of the year, as the US finds evidence that the group is setting up training camps.
2016 - Following years of conflict, a new UN-backed "unity" government is installed in a naval base in Tripoli. It faces opposition from two rival governments and a host of militias.
By the summer of 2011, the limited intervention to protect civilians had drifted into an opportunist policy of regime change, the committee said.
"That policy was not underpinned by a strategy to support and shape post-Gaddafi Libya.
"The result was political and economic collapse, inter-militia and inter-tribal warfare, humanitarian and migrant crises, widespread human rights violations, the spread of Gaddafi regime weapons across the region and the growth of Isil in North Africa.
"Through his decision-making in the National Security Council, former prime minister David Cameron was ultimately responsible for the failure to develop a coherent Libya strategy."
The MPs said Libya had been the "first test " for the NSC, which was set up in 2010 to coordinate responses to security threats and integrate the work of various relevant government departments.
The committee said there should now be an independent review of the operation of the NSC, which is chaired by the prime minister, to see if it had succeeded in addressing the weaknesses in government decision-making identified in the run-up to the 2003 invasion of Iraq.
The Foreign Office defended the intervention.
"Muammar Gaddafi was unpredictable and he had the means and motivation to carry out his threats," a spokesman said.
"His actions could not be ignored and required decisive and collective international action. Throughout the campaign we stayed within the United Nations mandate to protect civilians.
"After four decades of Gaddafi misrule, Libya undoubtedly faces huge challenges. The UK will continue to play a leading role within the international community to support the internationally recognised Libyan Government of National Accord."


Politicians on all sides of the House have been preparing for a fight over civil liberties and protection of personal privacy.

Most decided to hold their fire when confronted by a home secretary armed with a weighty and complex set of powers. But there are likely to be further skirmishes as parliament considers the details of her proposals.
Theresa May's central argument is that the powers of the police and intelligence agencies need to be updated for the digital age, when criminals and terrorists are finding new means of communication.
The most contentious issue is who should authorise the interception of communications.
Her plan for the home secretary to approve warrants but then to require the approval of a judge seems to have appeased many of her critics. But there are still big concerns over the demand for internet companies to keep a record of which websites we use, even though they won't retain more details of our internet use.
The shadow home secretary Andy Burnham set the tone of the debate when he urged MPs to send a unified message that the proposals were "neither a snoopers' charter nor a plan for mass surveillance".
He said Theresa May had broadly got the balance right but there would be fears in Muslim communities that the powers could be used disproportionately.
Some of the home secretary's most dangerous critics are on her own side. David Davis, a former shadow home secretary, said the bill was a step in the right direction.
But he questioned who would appoint the judges who would sign the intercept warrants and raised concerns about the bulk retention of data.
One of Mrs May's former colleagues, the ex-Northern Ireland Secretary Owen Paterson, had very different concerns.
Mr Paterson, who signed warrants when he was in office, said he believed such decisions should be taken by elected politicians and feared involving a judge would mean delays and complications on urgent cases.
The former Liberal Democrat leader Nick Clegg helped to kill off a previous bill which he called the "snoopers' charter" when he was in coalition with the Tories.
He said today's proposals were "much improved", but warned: "I have a feeling under the bonnet it still retains some of the flaws of its predecessor."
This is a draft bill and now faces detailed consideration in the Lords as well as the Commons. The home secretary is braced for further challenges but will be hugely relieved to have got through this critical session in the House largely unscathed.
