New Zealand took a 1-0 lead in the three-match Chappell-Hadlee series with a 159-run victory over Australia.

In the first ODI between the teams since Australia won the World Cup final in March last year, Martin Guptill hit five sixes in his 90 from 76 balls.
There were 13 sixes in total as the Black Caps posted 307-8 after being put in at Auckland's Eden Park.
Australia, who recently lost a Twenty20 series 3-0 to India, were 41-6 after nine overs and all out for 148.
It was a fifth successive limited-overs defeat for the Australians, who also lost the last of a five-match one-day international series with India.
They are without coach Darren Lehmann, who will miss the series as he recovers from deep vein thrombosis.
New Zealand scored only one run in the opening two overs before skipper Brendon McCullum, in his final appearance at Eden Park before retirement, hit 20 in four balls from Josh Hazlewood.
After McCullum fell for 44, Guptill moved to 50 from 47 balls with a six and a four in consecutive deliveries, but was denied an 11th ODI century when he was run out by a direct hit from Glenn Maxwell in the 25th over.
In Australia's reply, Black Caps paceman Matt Henry - overlooked for the World Twenty20 - took 3-20 in his first four overs, including the wicket of captain Steve Smith, who was bowled off the inside edge for 18.
Trent Boult, meanwhile, took 3-21 in his opening five overs, dismissing Maxwell and Mitchell Marsh in the same over.
He also removed key opener David Warner lbw for 12, a decision not reviewed by the Australians though replays showed the ball would have missed the stumps.
The second match of the series takes place in Wellington on Saturday.


The Met Police homicide unit is investigating the case of a serving police officer missing for five days.

PC Gordon Semple, from Greenhithe, Kent, was last seen on 1 April in the London Bridge area of London.
He had a work meeting at the Shard's Shangri-La hotel and left at about 12:30 BST. He was seen on CCTV in Great Guilford Street at 15:00 BST.
His partner reported him missing later that night. His niece Kerry Nicholas said the family was "very worried".
She told BBC News: "This is completely out of character for him.
"He is just a very outgoing, sociable guy. Very happy-go-lucky.
"He wasn't on any medication or anything and we have no reason to suspect he would just disappear without telling anyone.
"Nothing like this has ever happened to him before."
A missing page has been set up on Facebook.
The family said he enjoyed travelling to Thailand, but was not aware he had been planning any trips abroad.
PC Semple is described as white, 5ft 10ins (1.7m) tall, of a large build with a shaved head. He was last seen wearing brown shoes, dark trousers and a lilac shirt.
The 59-year-old is originally from Inverness and works with the Met Police anti-social behaviour unit in Westminster.
He has no children but still has family in Scotland.
Det Ch Insp Cliff Lyons said the force was keeping an open mind as to the circumstances of PC Semple's disappearance.
The case was being treated as a high-risk missing person's inquiry, but because of concerns for his welfare the homicide unit was taking the lead, the Met said.
Anyone with information can call the Met anonymously or contact Crimestoppers.


More than half of children in South Sudan are not in school, the highest proportion in any country, UN children's agency Unicef has said.

Government forces have been battling rebels for the past two years, although a peace deal was signed in August.
Niger is a close second, with 47% unable to attend school, followed by Sudan (41%) and Afghanistan (40%).
Worldwide, some 24 million children of more than 109 million living in nations at war are not in school, Unicef said.
Even before the conflict began, 1.4 million children were already missing class in South Sudan, Unicef said.
Since the war broke out, more than 800 schools have been demolished and more than 400,000 children had to abandon their classrooms, the agency said.
Despite the peace agreement, violence persists in some areas.
Only one in 10 South Sudanese students who enter school finish primary education amid a shortage of facilities and trained teachers, said Phuong T Nguyen, Unicef's chief of education for South Sudan.
"There is a very, very low budget from the government to the education sector," she said. "It is not holding steady and we see a decline."
Enrolment went up from under 30% after South Sudan became independent in 2011, but the war and a lack of school buildings and qualified teachers have slowed the growth, according to a South Sudanese official, the AP news agency reports.


Police have appealed for help to track a car used in an attack on a police patrol car in west Belfast.

A military assault rifle is believed to have been used and up to eight shots struck the passenger's side of the car at Rossnareen Avenue on Thursday.
Two officers who were in the car were not injured but were said to have been badly shaken.
Police said they believe the gunman travelled to and from the scene in a black BMW 3 Series.
It had been fitted with a false Republic of Ireland registration plate and was later found on fire in Cluain Mor Drive in Belfast.
The car had been reported stolen from an address in Ashbourne in County Meath, on 7 September.
Police said it was "critical" to the investigation that they received information on the car's movements from that date up until the attack.
They added that both the owner of the stolen car and the individual whose car registration was duplicated on the false plates had no involvement in the attack.


The Dáil meets later in what is expected to be an inconclusive attempt to elect a taoiseach.

Acting Taoiseach Enda Kenny of Fine Gael and his Fianna Fáil counterpart Micheál Martin are likely to meet later to discuss options for government.
Mr Kenny insisted at a party meeting last on Tuesday he would not consider a short-term deal.
Irish politicians have been attempting to form a workable coalition since February's general election.
The Dáil last met on 10 March, when TDs failed to elect a taoiseach to form a government..
It is expected that an inconclusive vote will pave the way for the meeting between Mr Kenny and Mr Martin.
Following the February election to the Dáil, Fine Gael has 50 seats, Fianna Fáil 44, Sinn Féin 23 and the Labour Party got seven.


Having a game called off due to Mother Nature is always frustrating - but travelling half the length of the country and turning up at the ground before the decision is made is even worse.

We trained as normal on Friday morning before our 418-mile round trip to Accrington, knowing full well that rain was due 'up north'.
But I didn't think about the possibility of the game being postponed because as soon as you do, your preparation suffers.
We set off up the M40 and proceeded to hit all the usual Friday afternoon traffic, so we had a quick stop off at Keele services to stretch the legs and pick up some snacks.
Once at the hotel, I had some dinner and a swim before bed, still hoping that all the weather forecasts we kept watching were going to be wrong.
As all parents will know, my body clock is set to the precise time that my daughter wakes up every morning, but I decided that seven am was too early for breakfast on a match day and managed to doze for an hour before heading down at eight o'clock, leaving my room-mate Sam Wood to sleep on in peace.
The gaffer, Gareth Ainsworth, set off to the ground before us to look at the pitch so we missed our usual team meeting at the hotel.
We were all following the Twitter updates from the official Accrington account and although the game was still on, the wording made us doubt whether any football would be played.
When we got to the ground and saw the puddles starting to form on the pitch, it was obvious there was no way we were going to be able to get a game on.
Our kit man told me that an hour before we got there the pitch was still playable, but the sheer volume of rain had made the groundstaff's job of keeping the pitch in a playable condition impossible.
In that situation, you feel absolutely gutted that the game is off. All the preparation, the travel, the opportunity to pick up points is gone.
We had a bit of fun at the kit-man's expense after he laid out all our kit and boots and then had to pack it all up again. Then we felt bad and helped him before we jumped back on the coach.
It was so disappointing to hear about our supporters who had spent money and time on travelling up to Accrington only to have to jump straight back in the car and head home with the prospect of repeating the trip on a Tuesday after work.
Like all football fans, our supporters spend a lot of money following us and we all really felt for them.
Luckily, the hotel we stayed in on the outskirts of Bury had a sizeable gym so we went straight back there, having only left around an hour or so previously.
Our fitness coach set up three stations. Cardio work on the bikes, upper body including some core work, and a lower leg circuit.
Some lads, including myself, love the gym and actually enjoy these kinds of sessions whilst others dislike the gym and find it a chore, but we all got the work done before jumping back on the coach, which now felt like our second home.
The journey home was weird as we weren't buzzing about picking up three points or agonising over a defeat; they're the two usual extremes on the coach journey home from games.
Back to the training ground just before eight pm, there was nothing else to do except go home and watch the boxing.


The US has issued a formal request to China to deliver an unmanned underwater drone that was seized in international waters, US officials say.

The Chinese navy seized the US underwater research vessel in the South China Sea on Thursday, the US alleges.
The incident took place just as the USNS Bowditch, an oceanographic survey ship, was about to retrieve it.
The device, dubbed an "ocean glider", was used to test water salinity and temperature, officials say.
The data was part of an unclassified programme to map underwater channels, Pentagon spokesman Capt Jeff Davis told reporters.
"It was taken" by China, Capt Davis said during a press briefing on Friday.
"The UUV [unmanned underwater vehicle] was lawfully conducting a military survey in the waters of the South China Sea," he added.
"It's a sovereign immune vessel, clearly marked in English not to be removed from the water - that it was US property."
The Chinese seizure of a US navy drone only serves to increase uncertainty and tension between the US and China, coming in the same week as a US think tank published satellite images of anti-aircraft missiles on China's artificial islands in the South China Seas and in the aftermath of remarks from US President-elect Donald Trump criticising China for building what he called a "massive fortress" in the region.
Despite previous statements that China had no intention of militarising the islands, the Chinese Defence Ministry defended what it described as "necessary military facilities" which it called "proper and legitimate".
Since Mr Trump questioned the so-called "One China" policy which Beijing describes as the 'political bedrock' of the US China relationship, China has also mounted fighter exercises over the Taiwan Strait.
The Obama administration has reaffirmed what it called its "unwavering commitment" to the "One China" policy but the seizure of a US navy drone may be Beijing's way of sending a message to the incoming administration that it too has ways of disrupting expectations and upsetting the status quo.
The encounter occurred in the South China Sea about 50 miles (80km) northwest of Subic Bay, Philippines, the US says.
"The Chinese navy ship ASR-510, a Dalang III-class ship, approached within 500 yards of the Bowditch, launched a small boat, and seized the UUV," the Pentagon said in a statement.
The Bowditch made radio contact with the Chinese ship to demand its immediate return but were "ignored".
"This is not the sort of conduct we expect from professional navies," Capt Davis added.
The seizure will likely add to US concerns about the growing military posture taken by China in the South China Sea.
A US think tank reported this week that aerial imagery shows that China has installed weaponry along seven artificial islands they have built at sea, despite US protests.
In November 2015, two US B-52 bomber planes flew over the man-made islands, known as the Spratly Islands.
Pentagon Press Secretary Peter Cook said the device was a "sovereign immune vessel of the United States" and demanded its immediate return from China.
Senator Ben Cardin, the top Democrat on the Senate Foreign Relations committee, called the seizure "a remarkably brazen violation of international law".
Senior Republican Senator John McCain said the US should not tolerate "such outrageous conduct", adding that "this brazen provocation fits a pattern of increasingly destabilizing Chinese behaviour, including bullying its neighbours and militarising the South China Sea".
"This behaviour will continue until it is met with a strong and determined US response, which until now the Obama administration has failed to provide," Mr McCain added.

After months of waiting, the Breaking Bad prequel Better Call Saul has been given a release date.

The spinoff, starring Bob Odenkirk, will debut in the US on AMC on 8 February, with its second episode due to air the following night.
It will then be shown in weekly instalments every Monday.
There's still no word on a UK release date, though the show is expected to arrive on Netflix across Europe shortly after its AMC run.
Following a series of short clips and a behind-the-scenes mini-feature, a new teaser has been released.
Entitled Tingle Fingers, the preview is set in a ransacked hotel room.
There's a cigar burning in an ashtray, a set of high heels discarded on the floor and a vibrating bed.
AMC president Charlie Collier has confirmed that the series will focus on the lawyer's pre-Goodman life as Jimmy McGill.
"We're going to introduce Jimmy McGill to the world. Known to Breaking Bad fans as Saul Goodman, viewers will soon discover Saul wasn't always Albuquerque's top criminal (criminal) lawyer," said Collier.
Jonathan Banks, who played Mike Ehrmantraut, will also return for the prequel, with new cast additions including Rhea Seehorn, Michael Mando and Julie Ann Emery.
Although it is yet to be confirmed, Breaking Bad creator Vince Gilligan has previously said that Bryan Cranston and his co-star Aaron Paul, who played Jesse Pinkman in the show, are likely to feature in the forthcoming spin-off Better Call Saul.
Breaking Bad told the story of a high school chemistry teacher Walter White, played by Cranston, who produced methamphetamine with a former student and became a fearsome drug kingpin.

The Belfast Giants will go into the second leg of the Challenge Cup semi-final one goal up on the Cardiff Devils after a dramatic 5-4 win on Wednesday.

The Giants fought back from two goals down and will have home advantage when the Elite League's top two sides meet again on 8 February.
The sides were locked at 4-4 going into the final minute of the match.
Jim Vandermeer got the late goal, putting Belfast into the lead for the first time.
There was a controversial start to the match as Belfast's player-coach Derrick Walser was given a 10-minute penalty for 'skating before the end of the anthem'.
Layne Ulmer's powerplay opener and a second goal by Gleason Fournier had Cardiff in command at Ice Arena Wales but Colin Shields netted on the powerplay, from Walser's pass, to make it 2-1.
Guillaume Douicet restored Cardiff's two-goal cushion before Chris Higgins got a second for the Giants.
Joey Martin, though, made it 4-2 right at the end of the second period with the Giants claiming time was actually up before the goal was scored.
The Giants, one point behind the Devils at the top of the league, scored three without reply in the third period, the goals coming from Shields, Brandon Benedict and Vandermeer.


A Chinese tourist has died in Hong Kong a day after being beaten up during a so-called "forced shopping" tour.

Operators of such discounted tours try to recoup costs by pressuring tourists to buy goods at selected stores.
Police said the victim, 54, intervened when a fellow tourist got into a fight with a tour guide after refusing to buy anything at a jewellery shop.
At least four people have been arrested and the Hong Kong Tourist Board (HKTB) expressed regret over the incident.
"The HKTB has zero tolerance for any act that impacts the hospitable image of Hong Kong, particularly acts of violence," it said in a statement.
The victim, a male building contractor from north-east China, was found lying unconscious outside the shop in Kowloon on Monday morning.
He tried to mediate in a fight between two women - believed to be the tour leader and one of the tourists - before he and the female tourist were attacked by a group of men who dragged them onto the street and beat them, police said
The two women, aged 32 and 53, have been arrested, along with two men, one a 44-year-old Hong Kong resident and the other a 32-year-old mainlander. Police say they are still searching for two other suspects.
On the mainland the man's death prompted calls for a boycott of travel to Hong Kong.
China has introduced measures aimed at stopping the practice of forced shopping, but they have had little effect.
Tensions between Hong Kongers and mainland Chinese have been rising as the number of mainland visitors has increased.
The visitors have driven a tourism boom - but local residents blame mainlanders for pushing up prices.
They also resent what they see as mainlanders' coarse behaviour, such as eating on the subway and blocking pavements with oversized suitcases.
China's National Tourism Administration has urged Hong Kong authorities to protect mainland tourists' rights.


Huddersfield have been fined £12,500 and Burton Albion must pay £5,000 after admitting a Football Association charge of failing to control their players.

The charge related to an incident which led to Huddersfield's Dean Whitehead being sent off during a 1-0 defeat at the John Smith's Stadium on 1 April.
Whitehead was given a second yellow card after a clash with Tom Flanagan.
Huddersfield have been handed a bigger fine after being punished for a similar incident against Leeds in February.
The FA said players failed to conduct themselves "in an orderly fashion" around the 88th minute of the Championship match.
Burton moved up to 19th thanks to Jackson Irvine's stoppage-time winner, four points off the relegation places.


Great Britain's Lizzy Yarnold completed a career 'grand slam' with victory at the Skeleton World Championships.

Media playback is not supported on this device
The 26-year-old clocked a second track record of the competition in her final run at Winterberg to beat German Jacqueline Loelling by 0.67 seconds, with Canada's Elisabeth Vathje third.
"I can't quite take it all in. It's all I ever wanted," she told BBC Sport.
Yarnold won European gold earlier this year to add to her successes at the Winter Olympics and World Cup in 2014.
Her fellow Britons Laura Deas and Rose McGrandle were seventh and ninth respectively.
Yarnold, who won won bronze at the 2012 World Championships and was fourth the following year, clocked 57.44 seconds in her first run on Friday to break the track record.
And she improved her own mark a day later, a 57.42 run giving her victory in a combined time over four runs of three minutes 49.95 seconds.
Deas, 25, finished 1:58 adrift of her compatriot, with 28-year-old McGrandle another 0.18 back.


The races for the Republican and Democratic presidential nominations are taking shaping now that Iowans have had their say.

In some cases, the results confirmed conventional wisdom.
In others, it totally reshaped it.
Here are five things we learned after a remarkable evening in America's heartland.
For the past few months it seemed as though the New York real estate mogul had become an unrivalled political savant. Every move he made, no matter how questionable, only strengthened his standing among conservative voters.
That bubble, however, has burst. Despite leading in the Iowa polls for the past several weeks, rival Ted Cruz posted a solid victory on caucus night. In the end Mr Trump's much-heralded cadre of new voters didn't show up in the predicted numbers and Mr Cruz's formidable ground game, backed by strong evangelical support, carried the day.
This hardly means it's the end for Mr Trump. He may well hold onto his large lead in New Hampshire, a state where the conservative voters often embrace the renegade outsider, and find success in the Southern primaries that follow. The notion that the New Yorker could steamroll his way to the Republican nomination, however, has now been firmly dispelled.
Florida Senator Marco Rubio's speech in Iowa on Monday night sounded more like a victory celebration than the concession speech of a third-place finisher. By finishing with 23% of the vote, however - a hair's breadth from second-place Trump - Mr Rubio shattered pre-caucus expectations.
Now he's well positioned to gain new support in New Hampshire, as voters looking to stop outsider candidates Cruz and Trump rally to his side.
This is the kind of Iowa result that candidates like New Jersey's Chris Christie, former Florida Governor Jeb Bush and Ohio Governor John Kasich were dreading. They have placed all their hopes in New Hampshire, and now they'll have to face off against a man who has the political wind at his back.
The polls for Mr Rubio in the coming states haven't looked particularly encouraging, but that could quickly change. And even if he suffers setbacks in the Southern states that follow New Hampshire, he likely will have the resources to wage a long fight for the nomination.
At this point it comes as little surprise that Vermont Senator Bernie Sanders and former Secretary of State Hillary Clinton finished in a virtual tie in Iowa - polls had been indicating such a result was likely.
Nevertheless, the outcome marks a significant achievement for Mr Sanders, who was polling in single digits in Iowa six months ago.
Mrs Clinton is simply not going to be able to deliver the knockout punch to her rival the way she once had hoped. Instead, she faces a likely defeat in New Hampshire - where the Vermonter is strong - and then a protracted fight across the country that could last at least through March.
She still has the greater financial resources and a much more developed campaign infrastructure, but she had those advantages in Iowa as well. The electorate will change, however - becoming more moderate and more ethnically diverse. There is more hospitable ground ahead for Mrs Clinton - but a nomination victory, if it comes, will take time to realise.
If Mr Cruz had been defeated in Iowa it would have been a devastating blow to his campaign. He had raised expectations of a victory in the caucuses and heralded it as proof that he could build a coalition of evangelical, grass-roots Tea Party and libertarian voters.
As it turns out, that coalition exists - and it will likely re-emerge after New Hampshire, as South Carolina and other Southern states hold their primary contests.
Mr Cruz has nearly $20m in campaign cash on hand and supporting political committees with even greater resources. He's built a political machine that can operate through the entire primary calendar and, if necessary, wage a two-front battle with Mr Trump and an establishment-backed candidate like Mr Rubio.
In his victory speech on Monday night, Mr Cruz credited his grass-roots organisation - as he should - but he also gave Republicans a look at a more moderate, general-election version of himself. He'll need to convince his party that he is a candidate who can beat the Democrats in November. This was his first step toward making that pitch.
Democrat Martin O'Malley is gone, as is Republican Mike Huckabee and - in all likelihood, Rick Santorum.
On Monday night rumours abounded that Ben Carson was poised to exit. Although his camp quickly denied this, the retired surgeon's 9% performance in a state that once viewed him as a front-runner likely means the end is near.
Carly Fiorina's bid is on life support, and Rand Paul - at one point thought to be a contender for the nomination - garnered less than 5%, a far cry from his father's 21% in Iowa just four years ago.
New Hampshire will likely cull the herd even further, threatening the future of candidates like Mr Bush, Mr Christie and Mr Kasich if they can't slow Mr Rubio's momentum.
The Republican race for the nomination isn't likely to end anytime soon, but there are about to be a lot fewer candidates on the debate stage in the coming weeks.


A verdict of accidental death has been recorded at the inquest on a mobility scooter rider who died after crashing through a first floor glass panel.

John Withers, 82, fell 4m (12ft) to his death at a NHS medical centre in Fareham, Hampshire, in September 2012.
An inquest jury at Portsmouth Guildhall had previously heard the glass-panelled walkway Mr Withers had been using was "severely decayed".
Mr Withers was pronounced dead at the scene and died of head injuries.
Health and safety inspector Michael Baxter earlier said that after decades of exposure the walkway was "badly decayed", adding "all natural structural integrity was lost"
The coroner had heard that maintenance was the responsibility of the now defunct body NHS Portsmouth, but that despite the matter being referred 19 times it was not considered high priority.
Mr Withers' son Trevor told the inquest his father had been riding a mobility scooter for four years and the one he was on had been used for about six months.
He also said his father was "very safety conscious".


A Royal Marine from Northern Ireland has appeared in court charged with offences related to dissident republicanism, including bomb-making and storing weapons.

Ciarán Maxwell, 30, has been charged with one offence of terrorism, one of fraud and one of possessing cannabis.
He was arrested in Somerset last week after searches in Larne and Devon.
The serving Marine's arrest was understood to be connected to two arms dumps found in County Antrim this year.
Mr Maxwell was remanded in custody after a three-minute hearing at Westminster Magistrates' Court.
He will appear again in court on Monday, 5 September.
He is charged with manufacturing explosives, making devices and storing them in barrels in hides in England and Northern Ireland.
Ciarán Maxwell appeared in Westminster Magistrates' Court flanked in the dock between two plain-clothed police officers.
Wearing a grey sweatshirt, a stubble-type beard and short hair, he stood before the judge and confirmed his name, age and address in Devon.
The hearing lasted just three minutes. The judge remanded him in custody until he is due back in court on Monday.
The charges include obtaining articles for use in terrorism - specifically chemicals and components to make bombs - and having an image of an adapted police pass card.
The charges come as part of long-running investigation involving the Security Service (MI5), the Police Service of Northern Ireland and the South West Counter-Terrorism Unit, as well as Scotland Yard's Counter-Terrorism Unit, says BBC Home Affairs Correspondent Danny Shaw, who was at the court.
Mr Maxwell is accused of carrying out research resulting in "the creation of a library of documents" likely to be of use to terrorists.
The offences are alleged to have taken place between 1 January 2011 and the day of his arrest in Somerset, 24 August 2016.
Ciarán Maxwell: Full list of charges
A separate charge says that on 24 August, Mr Maxwell had a quantity of cannabis in his possession with intent to supply.
He has also been charged with fraud and is accused of having images of bank cards and associated CVC numbers for use in connection with fraud.
Mr Maxwell was arrested on 24 August by officers from the Metropolitan Police Service's counter-terrorism command, supported by Avon and Somerset and Devon and Cornwall Police.
The Marine, originally from Larne in County Antrim, was taken to a West Country police station in Somerset before being transferred to a London police station last Thursday.
He was questioned on suspicion of being involved in the preparation for acts of terrorism under Section Five of the Terrorism Act.
Property searches in Exminster are now complete, while searches at New Powderham Plantation in Devon will continue into next week.
Police Service of Northern Ireland searches in Larne, County Antrim, are ongoing.


A soldier has appeared in court charged with murdering a 24-year-old woman whose body was found in Gateshead.

Alice Ruggles, originally from Leicestershire, was found dead in a house in Rawling Road on Wednesday.
L/Cpl Trimaan Dhillon, also known as Harry, of the Royal Regiment of Scotland, was remanded in custody to reappear before Newcastle Crown Court on Tuesday.
The 25-year-old is based in Glencorse Barracks, Penicuik.


A former senior detective who led the investigation into the disappearance of County Tyrone teenager Arlene Arkinson has told the inquest into her death he destroyed all of his notes on the case.

The schoolgirl's body has never been found after she went missing in 1994.
Eric Anderson said there was no provision for the Royal Ulster Constabulary (RUC) to store the notes.
He added that police rules were that detectives were to keep documents for 10 years after their retirement.
Mr Anderson was giving evidence to the inquest for the first time, and appeared by video from his home.
He told the inquest he destroyed all of the notes "by burning and shredding" and did not keep copies, adding he had been under serious threat and found it difficult to keep the documents in a safe place.
He decided that destroying them "was the desirable thing to do".
Arlene, from Castlederg, disappeared after a night out in County Donegal in the Republic of Ireland.
Convicted child killer Robert Howard, who died in prison last year, was the main suspect in her disappearance.
Mr Anderson told the inquest it had been his decision to arrest Howard six weeks after Arlene disappeared because his inquiry pointed quite strongly to Howard having killed the girl.
Asked why Howard had not been arrested earlier, Mr Anderson said detectives wanted to get more information on Howard in order to successfully question him.
Howard was later released, and Mr Anderson was asked in court if he had concerns about that decision.
"It was the only decision open to us," he said.
"Did I want to charge him? Yes. Could I charge him? No."
It also emerged that after Howard's release, a 24-hour surveillance operation was put in place to track his activities and movements.
But Mr Anderson said Howard did nothing to incriminate himself.
Two years after Arlene disappeared, police searched and dug up parts of her sister's house and garden looking for the body.
Nothing was found.
Mr Anderson said the decision to carry out the search was taken by the then RUC chief constable Sir Hugh Annesley.
Sir Hugh ordered the search based on information from a "pillar of society", Mr Anderson added.


Former US Open champion Graeme McDowell has ruled out the possibility of replacing Rory McIlroy for Ireland at the Rio Olympics this summer.

The 36-year-old world number 73 was in line for an automatic place after McIlroy withdrew on Wednesday because of fears about the Zika virus.
But he said he would not compete because his wife is due to give birth.
"I made the decision many months ago, before I was on the team, that I would not travel," he said.
In addition to McIlroy, Fiji's Vijay Singh and Australia's Marc Leishman have already pulled out of the Games because of the Zika issue, while major winners Adam Scott and Louis Oosthuizen have chosen not to appear for scheduling and family reasons.
World number one Jason Day says he will talk to his family about the risks of the Zika virus before deciding whether to play at the Games.

US-based McDowell, who won the US Open in 2010, says his decision centred around his wife Kristin being due to give birth to their second child shortly after the Olympic tournament from 11-14 August.
His statement added: "I have always been a proud member of Ireland's golf teams, from my amateur career through to playing in four World Cups of Golf and I wish the Irish Olympic team the very best of luck in Rio."

Derek Lyle and Alex Harris each scored twice as Queen of the South routed Dumbarton in the Scottish Championship.

Darren Brownlie headed Queens ahead and Lyle's shot doubled their lead before the break.
Another from Lyle continued the hosts' dominance and Harris then fired his first.
Harris struck again and then set up Iain Russell's effort as the Palmerston side ended a run of three straight defeats with a handsome win.


A counter-piracy task force commanded by a Royal Navy officer has caught a group of Somalis believed responsible for two attacks in the Indian Ocean.

Pirates had exchanged gunfire with a super tanker on Friday 11 October before attacking a Spanish fishing vessel three days later.
Combined Maritime Forces (CMF) traced the pirates' skiffs from Britain's Royal Fleet Auxiliary Fort Victoria.
Nine men were caught and forces later destroyed two boats and equipment.
Commodore Jeremy Blunden, Royal Navy, Commander of CTF-151, said: "This is an excellent result.
"My multinational counter piracy forces swiftly located and dealt with this Somali pirate group, sending a clear message that piracy no longer pays."
Combined Task Force (CTF) 151, as the group is known, embarked on board RFA Fort Victoria with support from Australian guided-missile frigate HMAS Melbourne and South Korean destroyer ROKS Wang Geon.
The European Union flagship Dutch HNLMS Johan de Witt - flagship of the EU naval force in the area - and maritime patrol aircraft from Luxembourg were also part of the mission.
After tracing the pirates an HMAS Melbourne Seahawk guided the warship to their precise location,  500 nautical miles off the Somali coast, before a boarding team made the final approach to search the skiffs.
Commander Brian Schlegel, Royal Australian Navy, commanded HMAS Melbourne during the operation.
He said: "It is clear that there are still pirates out there determined to generate income from taking merchant ships hostage.
"Mariners have been served a timely reminder of the perils of transiting the Somali coastline."
CMF is a multinational naval partnership with 29 nation members. Its aim is to promotes security, stability and prosperity across 2.5 million square miles of international waters.


Women in India have been posting photographs of themselves enjoying a night out on social media in response to a politician who said a woman who was chased in her car by two men "should not have gone out so late at night".

Varnika Kundu, who works as a DJ in the northern city of Chandigarh, was returning home on Friday night when she was allegedly chased by the men, one of whom was Vikas Barala, the son of a prominent politician from India's governing Bharatiya Janata Party (BJP).
On Wednesday, Mr Barala was arrested - police say he stands accused of "stalking, drink-driving and attempt to kidnap".
Ms Kundu said she was "chased and almost kidnapped" and that she was "not lying raped and murdered in a ditch somewhere" only because police quickly responded to her distress call and rescued her.
After she wrote a Facebook post about her ordeal which went viral, senior BJP politician in Haryana state Ramveer Bhatti blamed Ms Kundu for what happened to her.
"The girl should not have gone out at 12 in the night," he told the CNN-News18 television channel. "Why was she driving so late in the night? The atmosphere is not right. We need to take care of ourselves."
Mr Bhatti then went on to tell The Times of India that "parents must take care of their children. They shouldn't allow them to roam at night. Children should come home on time, why stay out at night?"
This "victim shaming" didn't go down well, and soon women began posting photos of themselves out at night under the hashtag #AintNoCinderella.
The campaign was launched by Divya Spandana, head of the opposition Congress party's social media cell who is a popular film actress from the southern state of Karnataka and often goes by her screen name Ramya.
"Why shouldn't women go out after midnight? I'm asking people like Mr Bhatti who are they to set curfew hours for us? I want to ask him who is he to question us? This is such a regressive mindset," Ms Spandana told the BBC.
She started out by sending a message to some women on her WhatsApp group on Monday evening.
"Ladies, how often have you heard something regressive like this from the mouth of a 'leader' who doesn't know much better? I'll answer: too often," the message said.
"This time they're telling us when we can and cannot go out of the our houses. This has to STOP" she added.
Then, she posted an image of herself on Twitter and invited other women to do the same.
The campaign soon caught on and hundreds of women have since posted photographs on Facebook, Twitter and Instagram challenging patriarchal mindsets that always blame women.
Among the first to post a midnight selfie was Sharmistha Mukherjee, Congress party leader and daughter of former Indian president Pranab Mukherjee:
Many others followed up, often with defiant messages:
When journalist Palak Sharma posted her image, sipping a drink and winking at the camera, she got loads of messages appreciating her "bold stand":
"But in the last two days, I've received lots of threats too. I've been called a whore, a slut," she told the BBC.
"Think about it - I'm a journalist, I work for the government-run media, I'm no pushover and I'm being threatened for my tweet," she said.
"But I'm not afraid," Ms Sharma added. "Nothing is going to stop us, no amount of naysayers can frighten us. We aren't Cinderellas, we don't have to be home at midnight."
With more and more women joining the campaign, it seems many others are refusing to be intimidated too.


The prospect of industrial action by some Orkney Islands Council staff has taken a step closer.

Members of the GMB union have voted overwhelmingly to reject proposals for changes to the terms and conditions for frontline staff.
More than 98% of ballot papers returned opposed the council's proposals after a three-week consultative ballot.
The council has said no decisions have yet been made on the options, which are still at the consultation stage.
The union has described the plans as ''unacceptable, unfair and unsustainable''. The vote opens the way for a second ballot on whether to take industrial action.


Rangers' Mark Warburton has accused Celtic's Ronny Deila of being "disrespectful" if he said it is "old fashioned" to only play on grass.

Manager Deila was talking ahead of his game on Hamilton's artificial surface.
Counterpart Warburton had previously called for a ban on such pitches in Scotland's top flight.
"If Ronny did say that - if he did say that - I think that is disrespectful because you are entitled to your opinion," said the Rangers boss.
"The one line from that interview that jumps out for me was 'number one is a good grass pitch, number two is a good artificial pitch'.
"If you are happy to accept second best then go for the artificial pitch.
"If you want to set the highest standards then you go for the best quality grass pitch.
"That, for me, was the one sentence that summed it up."
Warburton had entered the debate after Martyn Waghorn picked up an injury on Kilmarnock's artificial surface that could sideline Rangers' top scorer for the rest of the season.
While Deila told newspapers on Wednesday that he prefers a good quality grass pitch to an artificial one, he said he had nothing against artificial pitches as long as they were good quality.
However, he repeated the criticism he made of New Douglas Park after his side won 2-1 there in October, saying it was "slippy".
However, Accies player-manager Martin Canning refutes the notion that players are more susceptible to injury when they are playing on artificial surfaces rather than grass.
"We train on it every day and I've never noticed that it's slippy," Canning said.
"I watched the game that Celtic played at Dundee United and Gavin Gunning slipped when Leigh Griffiths ran through and scored, so I don't think the pitch is any more slippy than a wet grass pitch. You just deal with the conditions."
Canning believes that Hamilton's surface it is better than many grass pitches in the Scottish Premiership.
"Our pitch in particular, we enjoy playing on," he said. "When you go up to places like Ross County, St Johnstone or Motherwell at times - and this is not having a go at the ground staff, it's just the conditions and weather we get in the country - to keep grass pitches in a good condition for a long time is difficult.
"I'm a big believer in artificial pitches and I'm 34, I've been playing on it for years, I train on it every day and I'm fine, so I don't think it does any damage to your body.
"We've got the statistics that prove it - that you're as likely to get injured on grass as you are on that.
"I don't think there's any higher risk of injury and it makes it a good game of football. You can get the ball down and play."


Fashion retailer Burberry has announced plans to relocate 300 jobs from its London offices to West Yorkshire as part of cost-saving measures.

The luxury brand said it plans to open a new business services centre in Leeds in October in a bid to save Â£100m.
Staff in London will be offered the chance to relocate or face redundancy.
Plans announced in 2015 for a Â£50m manufacturing and weaving facility in Leeds, however, remain on hold.
More stories from across Yorkshire
Burberry, best known for its trench coats and distinctive checks, described the relocation as an "important move".
The Leeds office will bring together teams from finance, HR and procurement, as well as some customer service and IT roles.
Chief finance officer Julie Brown has said the group was still committed to Yorkshire, but was "taking a moment to think through" its plans for a new facility in Leeds South Bank.
In April, shares in Burberry fell by 6%.


Christmas is usually regarded as the busiest period of the football calendar in England and even though the Women's Super League is halfway through its off-season, there has been no let-up in the speed of change sweeping through the game.

England and Arsenal defender Casey Stoney is writing a regular column for the BBC Sport website.
Here she gives her thoughts on the new England head coach Mark Sampson and why she decided to rejoin Arsenal Ladies.
Mark Sampson has been appointed as the new England manager, and there have been a huge number of transfers, with no fewer than nine members of his squad on the move - including my own switch from Lincoln to Arsenal.
It was a relatively quiet Christmas for me as I continue to recover from a foot operation which will mean I miss out on the England training camp in La Manga later this month, but I got the chance to meet Mark in December.

I already know him a little from playing against his former team Bristol but it was refreshing to sit down and get to know each other face to face. We talked about his visions for the future, whether I was in his plans, and what he wants and expects from his players. It was all positive.
Mark also said he was going to reassess the captaincy, which I absolutely understand.
Being the captain of your country is the biggest honour and something that I dreamed of as a young girl and that I would love to continue with - but I have to accept that he might want something different. All I can do is get fit, work hard, play well for my club and see what happens.
He already knew I wasn't going to La Manga, but he now knows I will be back training in a few weeks fighting for selection for the Cyprus Cup in March and Arsenal's Champions League quarter-final against Birmingham to give myself the best chance of being selected.
He is a different person to former boss Hope Powell, and has a different approach, so it will be interesting. Having spoken to him, I'm excited about the prospect of working with him.
It is also great that one of my role models growing up, Marieanne Spacey, has been appointed as assistant coach to the national team and I'm really happy that Brent Hills got the elite development role as he has got great experience in the development of younger players.

Keeping myself in Mark's thoughts was one of the reasons I moved to Arsenal.
They might have finished third in last season's Women's Super League but they still won the FA Cup and Continental Cup, so they are not going anywhere and are one of the biggest names in women's football.
The decision rested on playing in a team which is competing for silverware and, although I had a fantastic three years at Lincoln, finishing sixth out of eight teams in the league last season was disappointing.
Arsenal have lost some key players - Scotland international midfielder Kim Little, England defender Steph Houghton and England striker Ellen White - but it doesn't worry me at all. Being part of a side that is rebuilding again is the kind of challenge I relish.
I went down to London to meet manager Shelley Kerr and I think one of the main draws for me was the plans they have in place for the future. I was very impressed with her and the set-up, so I think it's a fantastic option and I'm really excited to rejoin the Gunners.
I began my career at Arsenal in 1999, where in addition to playing, I worked in the laundry washing the likes of Dennis Bergkamp's underpants.
I don't think I'll be doing that this time and it just shows you how far the game has come. This time we will be training four evenings a week, with two sessions during the day. They will look after our strength and conditioning as well so the only thing I will need to worry about is playing football and performing. That is all I want to do.
Arsenal might be going through a transition period but they still want to dominate the women's game as they have done in the past, so it wasn't a massively hard decision.
With Manchester City making a real statement as they come into the top division for the first time, and Liverpool looking to strengthen their position after winning the league last year, it is already looking like an exciting season ahead and I can't wait to get going again.

Getafe forward Miku has joined Celtic on a year-long loan, with the Scottish champions having an option to buy.

The 27-year-old Venenuela international, full name Nicolas Ladislao Fedor Flores, has been capped 40 times for his country.
Celtic manager Neil Lennon said: "He is a powerful striker and he is a player we rate very highly.
"His goalscoring record in La Liga has been very good. It was a department we thought we were a little short."
Lennon revealed that he is hoping to bolster his striking options further and that appears likely to be a free agent.
"We are hoping to bring one more striker in, but that does not necessarily have to be done tonight," said the manager.
Miku, who was linked with a move to Michael Laudrup's Swansea City, scored 12 goals last season as Getafe finished 11th in La Liga.
He began his career with Valencia before joining Getafe in 2010.
Miku has also had loan spells with Alcoyano, Salamanca, Ciudad Murcia and Gimnastic.


A burglary victim says he has been threatened with arrest after he put up a wanted banner on the side of his house to try and find the thief.

Builder Sebastian Stephenson, 34 from Croydon, hung the poster which said "Wanted: Dead or Alive" alongside a CCTV photograph of the alleged thief.
The police told him he had to change it as it was inciting public disorder.
The Met said Mr Stephenson had not been arrested and that the investigation into the theft continues.
Mr Stephenson said the alleged thief had targeted him four times and had taken more than Â£4,000 worth of tools.
After the first couple of thefts, he installed CCTV cameras outside his house which filmed the tools being taken.
He said he called the police saying "here is the burglar" and urged them to send a picture from the Met's Twitter accounts and other social media to raise awareness to other builders.
When this did not happen, Mr Stephenson uploaded the CCTV footage to YouTube and paid Â£300 for a Facebook post on the incident to be promoted to users in the Croydon area.
Still frustrated at the police's response, he decided to print the banner.
"I want him to drive back and see his face. [But] within 24 hours the police came back to arrest me for inciting public disorder and said I must take the sign down immediately.
When asked why he included the "Dead or Alive" line he said: "Everybody knows it's just a cowboy and western reference, like Clint Eastwood."
He has now marked out the word dead.
After the poster went up, he said he had people who lived close by to him saying they had had their tools stolen too.
"Burglary is important. My home has been violated. When I told my wife I was going away for work she said 'you're leaving me alone with a thief' - see it's affecting her.
"At night I'm checking the van through the window to see if it's still there. My children keep asking if I've caught the thief so it's on their mind.
"It's not low-level crime."
The Met said anyone with information should contact 101 or Crimestoppers.


British viewers are more likely than those in other developed nations to watch on-demand TV this Christmas, the UK's telecoms regulator Ofcom is predicting.

Its survey indicates 70% of UK adults, 31 million, watched TV via free catch-up services such as BBC iPlayer and ITV Hub in September and October.
Meanwhile, 16% of web-connected adults viewed catch-up TV on a tablet.
Traditional live TV remained the most popular way of tuning in, however.
Of the 9,000 individuals surveyed, more used these tech-savvy television services in the UK than in the US, France, Germany, Italy, Japan, Australia, Spain or Sweden.
"UK viewers won't be tied to the TV schedule this Christmas," Ofcom director of research James Thickett said.
"More than anywhere else, we're watching TV and films at a time that suits us, on a range of devices, in and out of the home.
"So this year, more people can fit their festive TV viewing around opening presents and carving the turkey."


Labour has announced it would guarantee three-year tenancy agreements with rent increases "capped" at the rate of inflation for those renting in the private sector in England.

The party hopes that this will help the 4.4m households (19%) renting privately. According to the English Housing Survey (EHS) the sector that has doubled in size since 2002. This is particularly among the young, labelled "Generation Rent".
In 2013-14, 48% of all households aged 25-34 rented privately. That's more than double the proportion in 2003-4 (21%). This is matched by a decreasing number of younger homeowners. In 1991, 67% of that age group were homeowners. By 2011/12, this had declined to 43%, according to the Office for National Statistics (ONS).
We also know that private renters move more frequently. In 2013-14, 35% of private renters had been in their home for less than a year, and 67% for less than three years. We don't know how often this is out of choice, for example due to the nature of their work, or in search of cheaper rents.
The English Housing Survey also indicated that the longer private renters had been in their home, the less rent they paid. As demand outstrips supply in the rental market, new tenants are being charged higher rents than people who have been in the same property for years.
Labour hopes landlords will also see a benefit to three-year tenancies - that, for example, tenants might be more likely to care for a property if they know they'll be living there longer. Critics say rent controls will lead to substandard housing. They also say it might raise rents in the short term, with landlords putting up prices at the start of a lease.
It wouldn't be the first time that there have been rent controls in England. In 1915 the UK government imposed limits on the initial rent landlords could charge as well as any subsequent rises. According to the House of Commons library, at that time private rented housing made up about 90% of the housing stock.
While this was supposed to be a temporary measure, it was repeatedly extended because of the continued housing shortage. Rental control for new lets only ended in 1989. By 1991 the private rented sector declined to 7% of the market.
In 2013-14, average weekly private rents were Â£281 in London and Â£145 outside of London, according to the EHS. The Office for National Statistics (ONS) publishes an Index of Private Housing Rental Prices (IPHRP), which measures the change in price of renting from private landlords. It's important to note that the ONS says the IPHRP is a new "experimental statistic". Since January 2012, annual English rental price increases have ranged from 1.4% to 3% year-on-year, with March 2015 prices 2.1% higher than a year earlier. Excluding London, English rental prices increased 1.5% for the same period.
The ONS publishes information on rent increases going back to 2006. Annual rent increases were at their highest in 2008, but rents actually fell during 2010, before rising again from 2011. If you exclude London, rents have increased less than inflation for almost all the period since 2008 until very recently, when inflation has been very low. Private renters spend proportionally more of their income on housing costs than mortgagors, although private renters tend to earn less.
On average, owner occupiers buying with a mortgage spent 20% of their income on their mortgage whilst private renters spent 40%, according to the 2012/13 English Housing Survey.

A 40-year-old man arrested on suspicion of terror offences has been released on bail until May.

He was held in Crawley, West Sussex, on Wednesday morning under Section 11 of the Terrorism Act and a residential property was searched.
The arrest is understood to be connected to the conflict in Syria.
But a community leader said the case was not thought to be linked to another man from Crawley, who died in a suspected suicide attack in Syria.
Abdul Waheed Majeed, 41, died after driving a truck bomb into the gates of a prison in Aleppo in February last year. The father-of-three had left the UK in 2013, telling his family he was going on a humanitarian mission to Syria.
Sussex Police confirmed the man's arrest on Wednesday, by its officers and the South East Counter Terrorism Unit, was not connected to any immediate threat in the UK.
The man was released on bail on Wednesday evening, a spokesman for the force added.
Crawley MP Henry Smith said police had informed him of the arrest, thought to be in the Langley Green area of the town.
He said: "I understand he has been arrested in relation to membership of organisations which are connected with activity to the Syrian civil war."
Community leader Arif Syed said he had known the arrested man for seven or eight years and people in Crawley were "shocked and surprised" at the news.


A man found stabbed to death in a South Gloucestershire village on Christmas Eve was killed elsewhere, police have said.

The body of Mohammed Abdurezek, 31, was found in Gibbs Lane, Siston, at 10.10am on Saturday.
Officers want to retrace his steps in the hours before his death, locate his mobile phone and identify the vehicle he was transported in.
A post-mortem examination confirmed Mr Abdurezek died of multiple stab wounds.
Det Ch Insp James Riccio, of Avon and Somerset Police, said: "We have a team of officers and staff working tirelessly to find out who killed Mohammed and why.
"We don't believe he was murdered at the location where his body was found, and we're actively tracing his movements in the hours and days leading up to his death to establish where he was killed.
"Our focus is also on trying to identify the vehicle used to transport Mohammed's body to Siston and CCTV is being examined from the local area."
Police would like to speak anybody who may have seen a suspicious vehicle, or a parked vehicle, in the area around Siston Lane between the evening of 21 December and Christmas Eve morning.
Mr Abdurezek was based in Bristol but had links to other locations in the UK, including Swansea and Newcastle.
Mr Riccio added: "We're in contact with some of Mohammed's friends and associates to try to trace any family members or next of kin, who we believe live abroad.
"I firmly believe someone has information which could help establish who killed Mohammed. I'd ask them to call us immediately."


Concerns have been raised over access to banks in rural areas after HSBC announced the closure of a branch in Powys.

The bank said its Machynlleth branch would shut in the summer after a dramatic fall in customers.
Of the 28 banks that shut in Wales last year, 10 were "last bank in town" closures.
Residents and businesses have told BBC Wales the loss of local branches is a "massive inconvenience".
Montgomery, in Powys, and Tregaron, in Ceredigion, are among the towns which have lost local banks.
Eight branches in Wales have so far been scheduled to permanently lock their doors in 2015.
The major banks say the scaling back is driven by the massive rise in internet banking. Online UK accounts are now accessed seven million times a day.
Last week, Britain's banks reached a deal with the UK government on a protocol for shutting branches to minimise the damage caused to rural areas.
This includes working with the Post Office to allow customers to access more services.


This is peak elver fishing season on the River Severn but there are worries about illegal poaching and smuggling of these baby eels to the Far East.

So I spent a night out on the banks of the river to see how the problem is being tackled.
Elvers are amazing creatures. Small, transparent worm-like fish that arrive in the Severn from the Sargasso Sea in their millions. They work their way upstream and after five to 20 years living in the Severn they head back out to sea to breed.
Right now, it's full moon which means big tides and a huge bore, a surge wave, coming up the Severn at night.
The elvers are carried along and also swim with the bore, and at weirs and other obstacles they are lifted over the obstruction into the next part of the river.
There's something spooky about standing late at night by the river Severn and hearing the familiar noise of water rushing over a weir..., and then hearing the weir go silent as the bore arrives and lifts the river level above it.
Right now all along the river you'll find hundreds of elvermen fishing for elvers.
Believe it or not elvers are a delicacy, although not generally considered so in this country.
In Spain and elsewhere in Europe people enjoy them as tapas and tasty nibbles so each kilo the elvermen catch currently fetches £150. While we were out we heard tales of people catching 18kg of elvers in an evening which would earn them several thousands pounds.
Elvers are also considered a delicacy in the Far East. But since eels and elvers are endangered and because the demand from countries like China is so huge, export outside Europe has now been banned.
Of course where there's a ban and huge demand there's also money and smuggling. A kilo of elvers in China could cost £6,000. That's more than Beluga caviar.
For the first time in this country a large scale elver smuggling operation has been caught and stopped. At Heathrow a man was found trying to smuggle 200kg of elvers which would have a street value in his attempted destination of Hong Kong of £1.3m
In the wake of this teams from the Environment Agency have been stepping up their patrols and intelligence gathering with the help of law abiding elvermen along the Severn.
Because 60% of all the elvers caught on the Severn are not eaten, they actually go to help restock other areas in Europe where the population of eels has declined even further than here. And if the elvers we do have end up being smuggled to the Far East that will be bad news for the elvermen of the Severn and the eels themselves.


Many people have been protesting in America as they are angry about something called the Dakota Access Pipeline.

Newsround looks at exactly what this pipeline is, why it's being built and why it has caused disagreements.
The Dakota pipeline is a special pipe, which will be used to carry oil from the US state of North Dakota to another state called Illinois.
Once the oil gets to Illinois via the pipeline, it can be taken to special places called refineries, where oil is cleaned to make it ready to use.
Plans to develop the pipeline began in 2014. This week, the company behind the pipeline said it is getting ready to be used.
Until recently, there was a section of it still left to be built because the authorities were exploring other routes that this bit of the pipeline could take.
This was so that it wasn't built near a certain area called Standing Rock (find out more about why below).
But as soon as Donald Trump - who supports the pipeline - became the new US president at the beginning of 2017, builders were given the go-ahead to finish it off.
The finished line is 1,200 miles long and cost Â£2.8 billion to build.
It will be able to carry about 470,000 barrels of oil in a single day, running underneath both land and water, through four different US states.
Supporters of the pipeline say it is the safest way to transport oil to the rest of the country.
Not only that, but they say it is cheaper than carrying barrels of oil by train.
They also said that building it would create jobs for people.
Thousands of people have protested against the pipeline being built, including Native American tribes who live at an area called Standing Rock.
They are not happy as the final section of the pipeline crosses near here, and they think it could harm sacred burial sites and contaminate drinking water.
They also say that the government didn't speak to them before building it, which they should have done.
Many people have travelled to the Standing Rock area to protest with them, including Native Americans from other areas.
Other protestors do not agree with the pipeline because they do not think that fossil fuels - like oil - are good for the environment.
The protestors have said that they will not give up protecting their land, and so the protests continue.
They have also taken their argument to the courts to try to stop the pipeline from starting to be used, but we will have to wait to see what will happen.
On Monday, the company behind the pipeline said they are preparing to put the pipeline into full service.


Israeli forces have begun a major security operation in Arab areas of occupied East Jerusalem, after a surge in attacks by Palestinians.

On Wednesday morning police blocked entrances to Jabal Mukaber, a district that is home to three men accused of killing three Israelis on Tuesday.
The Israeli military also deployed hundreds of soldiers to assist.
Later, police said they shot dead a Palestinian who stabbed an Israeli woman at Jerusalem's main bus station.
A Palestinian also attempted to stab a policeman at the Damascus Gate of the walled Old City, but was shot dead by police, they added.
Is social media driving Israel-Palestinian violence?
Can Israel and the Palestinians contain spiralling violence?
Since the beginning of October, seven Israelis have been killed and dozens wounded in shooting and stabbing attacks, the Israeli authorities say.
At least 30 Palestinians have also been killed, including assailants, and hundreds have been injured, according to the Palestinian health ministry.
Speaking for the first time since the upsurge in violence began, Palestinian Authority President Mahmoud Abbas said Israeli actions were "threatening to spark a religious conflict that would burn everything".
He also accused Israel of carrying out "executions of our children in cold blood", highlighting the case of a 13-year-old Palestinian boy who was shot by Israeli police after he and a 15-year-old stabbed an Israeli on Monday.
Israeli Prime Minister Benjamin Netanyahu has described the Palestinian leader's comments as "lies and incitement", adding that the boy was alive in hospital, the Jerusalem Post reports.
He said on Tuesday the new security measures were aimed at "those who try murder and with all those who assist them".
On Tuesday night, Israel's security cabinet authorised police to close or surround "centres of friction and incitement" in Jerusalem.
It also announced that the homes of Palestinians who attacked Israelis would be demolished within days and never rebuilt, and that their families' right to live in Jerusalem would be taken away.
On Wednesday morning, a police spokeswoman told the AFP news agency that checkpoints were being set up at "the exits of Palestinian villages and neighbourhoods in East Jerusalem".
Israeli newspapers later reported that several entrances to Jabal Mukaber had been blocked by police, with neither people nor vehicles allowed in or out.
Across some roads leading into Arab neighbourhoods, a police vehicle blocks access; at other points, heavily armed police keep guard; at one access point, what was a lightly-staffed police checkpoint has been beefed up.
For years, Israel has tightly controlled access in and out of the West Bank and Gaza, where the vast majority of Palestinians live. East Jerusalem's checkpoints are not like the ones around the West Bank and Gaza; they are much more informal affairs. But they are, for the first time since 1967, restricting access to and from largely Arab East Jerusalem.
How long they will last is difficult to call. East Jerusalem's residents have the right to move freely through the city and Israel. It doesn't seem feasible to cut off whole neighbourhoods for long. And the roadblocks and checkpoints strike at the idea promulgated by the Israeli right that Jerusalem is the undivided capital of the Israeli state.
The checkpoints have the feel of short-term solution to an acute security problem. But with Israelis mourning their dead, and in fear of their lives, there is extraordinary pressure on the government to act.
Human Rights Watch warned on Tuesday night that locking down parts of East Jerusalem would "infringe upon the freedom of movement of all Palestinian residents rather than being a narrowly tailored response to a specific concern".
"The checkpoints are a recipe for harassment and abuse," said Sari Bashi, the group's Israel/Palestine country director, in a statement.
Meanwhile, the Israeli military said it was preparing to deploy six companies to assist police. Three hundred soldiers are already providing additional security under police command.
The security cabinet's decisions were made after the bloodiest day in Jerusalem since the latest wave of unrest began in early October.
In Tuesday's first attack, two Palestinian men boarded a bus and began shooting and stabbing passengers, killing two Israelis, police said. Police shot dead one of the assailants and wounded the other.
Just a few minutes later, another Palestinian rammed his car into a bus stop before getting out and stabbing people. The attacker was fatally shot by a security guard.
There were also two separate knife attacks in Raanana, a town in central Israel. Police identified the assailants as Palestinian residents of East Jerusalem.
Clashes between Palestinian protesters and Israeli soldiers meanwhile continued in the West Bank after Palestinian activists called for a "day of rage".
Palestinian medics said one Palestinian was killed by Israeli fire in Bethlehem.
The BBC's Yolande Knell in Jerusalem says the violence, coming at a time when peace prospects seem dim, has fuelled a sense of panic in Israel and raised fears of a new Palestinian uprising, or intifada.
There has been a spate of stabbings of Israelis - several of them fatal - by Palestinians since early October, and one apparent revenge stabbing by an Israeli. The attackers have struck in Jerusalem and central and northern Israel, and in the occupied West Bank. Israel has tightened security and its security forces have clashed with rioting Palestinians, leading to deaths on the Palestinian side. The violence has also spread to the border with Gaza.
After a period of relative quiet, violence between the two communities has spiralled since clashes erupted at a flashpoint Jerusalem holy site in mid-September. It was fuelled by rumours among Palestinians that Israel was attempting to alter a long-standing religious arrangement governing the site. Israel repeatedly dismissed the rumours as incitement. Soon afterwards, two Israelis were shot dead by Palestinians in the West Bank and the stabbing attacks began. Both Israel and the Palestinian authorities have accused one another of doing nothing to protect each other's communities.
There have been two organised uprisings by Palestinians against Israeli occupation, in the 1980s and early 2000s. With peace talks moribund, some observers have questioned whether we are now seeing a third. The stabbing attacks seem to be opportunistic and although they have been praised by militant groups, Palestinian leader Mahmoud Abbas has said Palestinians are not interested in a further escalation.


A £300,000 facelift is planned at Kelso racecourse to help bring its facilities up to modern standards.

The project would see a new entrance and office constructed at the Scottish Borders track.
Managing director Richard Landale said the works could be completed this summer ahead of their first meeting of the new season in September.
An application has been submitted to Scottish Borders Council to allow the renovation to be carried out.
Mr Landale said the current entrance dated back to the early 19th century and was no longer fit for purpose.
"More people are coming and we haven't been able to process them through the entrance and they have been standing out in the rain," he said.
"We are putting in a new ticketing system.
"We owe it to such loyal customers - we owe it to them to improve the experience.
"It is a significant investment, it is really going to bring the whole place up to the present day."
Kelso was one of the five racecourses across Scotland which announced a "bumper year" in 2015 earlier this year.
Its average attendance at 13 fixtures over the year rose by 12.6%, the largest increase among the Scottish sites.


Iraq is a country in the Middle East that has been in the news for many years because of fighting there.

20 October 2016 Last updated at 09:06 BST
Now it is being talked about a lot again, because there is a battle taking place over a city called Mosul.
Mosul is currently under the control of a extremist group that calls itself Islamic State (IS), but Iraqi soldiers want to take it back off them.
IS have extreme religious beliefs and use brutal violence against anyone who doesn't agree with their views.
They're trying to take control of areas of the Middle East, forcing people to live by very strict rules.
An army of thousands of troops is approaching Mosul in order to fight the IS soldiers who are in the city.

Scottish independence would "liberate" the rest of the UK and bring benefits to the North of England, according to the SNP's Christine Grahame.

The Borders MSP made the comment during a BBC-hosted debate in Northumberland ahead of the Scottish independence referendum on 18 September.
But Better Together campaigners claim independence would mean both regions competing for jobs and investment.
The debate took place in front of an audience at Berwick's Maltings Theatre.
Ms Grahame from the SNP said: "I think whatever happens independence will be the liberation of the rest of the United Kingdom.
"We've so much in common with the North of England and I believe Scottish independence will serve as a wake up call for the North to take on London."
But Carlisle's Conservative MP John Stevenson warned Scottish independence would damage both Scotland and his constituency.
He told the audience: "I think there's huge risks for Scotland if they choose to become an independent nation.
"At the moment Carlisle benefits from businesses investing in both England and Scotland, the real danger with independence is that you start to see businesses deciding not to invest on either side of the border."
The debate in Berwick highlighted how the conversation about Scottish Independence in the North East and Cumbria has changed in the past 12 months.
A year ago the main talking points would have focussed on the familiar topics of differing currencies and the potential for border checks on the A1.
The focus now is on the differences that already exist between England and Scotland.
Those taking part highlighted continually how people in England have to pay prescription charges and university tuition fees while people living just two miles up the road from Berwick in Scotland do not.
So the North East and Cumbria is slowly again looking at the idea of regional devolution, an issue that could provide enough content for its own televised debate programme.
David Rhodes
During the debate, hosted in Berwick, which has changed hands between England and Scotland 13 times, both sides also clashed over whether the North East and Cumbria should seek its own form of regional devolution from Westminster.
Craig Johnston from the RMT Union said Scottish independence would lead to Westminster agreeing to devolve more powers to the North of England.
"I hope Scotland does vote Yes so they can take the opportunity to take control of their own affairs," he said.
"The North of England needs to come together, and it needs to start arguing for proper devolved regional government that is democratically elected and has real powers."
In 2004 people in the North East of England rejected a devolved regional assembly, which had been proposed by the then Labour Deputy Prime Minister John Prescott.
Labour's Sedgefield MP Phil Wilson said people in the North East still did not want their own regional assembly.
He said: "Ten years ago people voted against the idea of a regional assembly but they did vote to create a unitary authority in County Durham."
"That authority has persuaded companies like Hitachi to build their new train factory in my constituency which will bring millions of pounds worth of investment to the region."
Scotland And Us will be shown at 22:35 BST on BBC One in the North East and Cumbria on Wednesday 3 September.


A 22-year-old woman has been arrested on suspicion of murder in connection with the fatal stabbing of a teenage boy in a fight in east London.

Joel Adesina, who was 15 and from Dagenham, was found stabbed in the abdomen on Bethnal Green Road, Tower Hamlets, at 23:00 GMT on Friday.
He was taken to hospital but died at 02:12 the following day.
An 18-year-old man arrested at the scene has been released with no further action to be taken, police said.
Detectives are keen to speak to anyone who may have witnessed an altercation in Padbury Court, just before the stabbing, between a group of male youths on foot and the occupants of a car.
The dispute carried on to nearby Gibraltar Walk.
Joel was part of the group on foot, police said.
A post-mortem examination will be held in due course.
Det Ch Insp Chris Jones said: "Anyone who may have witnessed this altercation or have information which could assist the investigation is asked to contact the police as soon as possible."


A man accused of a £180,000 online dating scam feigned laryngitis over the phone to dupe a bank into giving him a loan in his girlfriend's name, a court has heard.

The first time Susan Vasey knew of a £10,000 loan in her name was when police arrested her, she told a jury at Worcester Crown Court.
On hearing the recorded call she recognised the caller as her ex.
Matthew Samuels, of St Johns, Worcester denies 11 counts of fraud.
The 50-year-old, of Broadway Grove, is accused of tricking five women and his own stepson out of about £180,000.
Divorced Miss Vasey met Mr Samuels on dating site MatchAffinity.com when he was living in Staffordshire.
She told the jury he helped her get a finance deal on a Vauxhall Corsa through a car dealership he worked with.
But she claimed that, in early 2013, Mr Samuels told her the remaining £6,000 on the hire purchase agreement was due immediately.
Miss Vasey said she went to her bank and arranged a loan to buy the car outright but handed the money to Mr Samuels, who was to make the payment.
She claimed that in September last year she discovered paperwork showing the car had never been paid for and about £4,000 was outstanding on the original hire purchase deal.
She said: "I didn't know what had happened to the £6,000, I only knew it hadn't been used to settle the finance on the car."
The trial of Mr Samuels continues.


The London Bridge attacks set Donald Trump off on an extended Twitter rant over the past few days, reviving his calls for sweeping immigration action and renewing old feuds with Democrats, gun-control advocates and even the mayor of London.

While White House advisor Kellyanne Conway recently complained that the media have an "obsession with covering everything he says on Twitter and very little of what he does as president", Mr Trump is the pot-stirrer-in-chief, who has the power to drive debate and shape events.
Words, whether spoken or tweeted, have consequences. The president's Monday morning fusillade about his immigration policy is no exception. Here are five things we learned.
The lynchpin of the White House's defence of Mr Trump's two controversial immigration executive orders that set restrictions on immigration from a handful of majority-Muslim nations was that they had no connection to the anti-Muslim travel ban candidate Trump proposed back in December 2015.
The executive actions, they argued, constituted temporary restrictions and not a "ban", Muslim or otherwise.
The president has occasionally undercut that defence, by using the b-word in the past - leaving his aides to clean up the mess.
"It's not a Muslim ban. It's not a travel ban," Press Secretary Sean Spicer said back in January. "It's a vetting system to keep America safe."
On Monday morning, however, Mr Trump applied kerosene to that defence, set it ablaze and danced around its ashes.
"People, the lawyers and the courts can call it whatever they want," he tweeted, "but I am calling it what we need and what it is, a TRAVEL BAN."
Speaking of the judicial branch, the president on Monday morning went on the attack against the US legal system, calling the courts "slow and political".
The line is reminiscent of one of the president's more inflammatory tweets, when he lashed out against the federal judge who struck down his original immigration order.
"The opinion of this so-called judge, which essentially takes law-enforcement away from our country, is ridiculous and will be overturned!" he tweeted on 4 February.
The following day he issued an even more ominous warning, tweeting that the judge put the nation in peril and "if something bad happens blame him and the court system".
According to one theory, advanced by Lawfare blog's Jack Goldsmith, Mr Trump's seemingly ill-considered comments are all part of a plan to get the courts to strike down his immigration orders, freeing him to blame the judiciary for any subsequent attacks.
It may, however, be just another case of "what you see is what you get" with Mr Trump. He has feuded with judges throughout his professional life, including criticising the Mexican heritage of the man who was presiding over a lawsuit against his for-profit "university" during last year's presidential campaign.
President Trump is the same as candidate Trump is the same as businessman/TV star Trump. The stage may be different, but the man doesn't change.
Trump turns on his own
One of the more unusual components of Mr Trump's Monday morning diatribe was that he turned his Twitter invective on his own administration.
He lashed out at the Justice Department, headed by his close political confidant Jeff Sessions, for focusing its legal defence on what he called the "watered down, politically correct" second executive order on immigration and not the more sweeping first version that explicitly mentioned religion and caused confusion when it was first enforced at airport immigration checkpoints.
Justice Department lawyers have tried to decouple the second order from the original, arguing that it remedied the discriminatory portions of the earlier effort, clarified that those with legal residency were unaffected and focused exclusively on nations that had previously been determined to be of concern to US.
When the president signed that second order in early March, Spicer tweeted that it would "keep the nation safe".
"This revised order will bolster the security of the United States and our allies" Secretary of State Rex Tillerson said.
Now the president is bad-mouthing the very same action his aides had resolutely defended. He is clearly irked that his administration abandoned that first travel order, particularly after he told its critics that he would see them "in court".
If Mr Trump continues to casually undercut his own people, however, they'll be less willing to rush to his defence in the coming days - when the president may need them most.
Last week, for instance, multiple officials doggedly refused to say whether the president believes climate change is caused by human activity - a position most conservative officeholders, including the president's own Environmental Protection Agency head, accept. Such reluctance may be just a taste of things to come.
Why go out on a limb for a president who is standing by the tree with a saw in hand?
The president also dusted off one of his favourite terms from the 2016 campaign - "extreme vetting" - which he said is helping "keep our country safe".
The original justification for the travel ban orders was that they were a temporary measure to allow a rigorous review process to be instituted for all individuals entering the US. The first action's time frame for implementation was 90 days - which would have set the mark at 27 April.
The second order, signed on 6 March, reset the 90-day clock again - a point that was reached on Sunday.
The Weekly Standard's Michael Warren reached out to the Trump White House for further clarification on what vetting measures had been put in place and was directed to the State Department, which has yet to give respond.
Before Monday morning the last time the president himself had mentioned "extreme vetting" was in mid-February, when he said it "will be put in place, and it already is in place in many places".
Now extreme vetting - as a term at least - is back. But what is it? And if it's already in place, doesn't that erase the justification for implementing the travel ban?
It might - unless, of course, the ban was never intended to be temporary. That's a question the "slow and political" courts are likely to consider.
The president's social media onslaught comes after the latest round of stories about how the president was going to be more disciplined and focused, and less prone to Twitter tirades. Mr Trump's lawyers, we were told, were counselling him to tamp things down, lest his comments land him in more hot water.
The president has apparently disregarded this advice yet again and is trying his best to fight old battles and rekindle old feuds.
Why? Perhaps it's because there is a very dark storm cloud on the horizon. On Thursday former FBI Director James Comey - the man Mr Trump dramatically fired and has since very publicly insulted - will testify under oath before a Senate inquiry into Russia's meddling in the US presidential election. He's expected to discuss reports that the president asked him to pledge his loyalty and pressured him to back off from his investigation of Trump foreign policy advisor Michael Flynn.
Given Mr Comey's reputation for political independence and morale certitude - combined with the possibility that he has contemporaneous memos documenting his interactions with the president - the testimony could be disastrous for the White House.
At the very least, it will be a spectacle the likes of which Washington has not seen in decades.
The president could be eager to change the subject or, at the very least, deflect some attention. If so, the past few days of Twitter invective could be just the start.


Markets in Asia were mostly up on Monday, following stocks in the US, which ended the week higher after recovering losses.

In Australia, the benchmark S&P/ASX 200 closed up 0.23% at 5,827.50 points.
The index finished the day in positive territory despite disappointing results from of Australia's biggest lenders, Westpac.
The bank posted a cash profit of 3.78bn Australian dollars ($2.98bn; Â£1.96bn) for the six months to March.
Analysts said the results were poor and a "big miss".
Shares in the bank fell by more than 4.5% on the results.
In China, Hong Kong's Hang Seng index closed flat at 28,123.82, while the Shanghai Composite was up 0.9% at 4,480.46 points.
A report released on Monday showed factory activity in China had contracted in April.
HSBC's purchasing managers' (PMI) index was 48.9 for April, the lowest level in about a year, and down from March's reading of 49.6.
A reading of below on the index 50 indicates a contraction.
Analysts said investors would probably welcome the disappointing data, as it could spur the government to introduce fresh stimulus measures to help boost the economy.
Meanwhile, South Korea's benchmark Kospi index closed up 0.24% at 2,132.23 points.
Investors shrugged off a separate HSBC report on South Korea's manufacturing sector which showed activity fell to a seasonally adjusted 48.8.
HSBC's PMI reading for April was its lowest since October last year.
The Nikkei 225 index was closed on Monday, as Japanese markets are shut for the Golden Week holiday. They will reopen on Thursday.


Fernando Alonso is poised to start Sunday's Italian Grand Prix from the back of the grid as a result of the latest in a series of engine penalties.

McLaren's engine partner Honda is planning an engine upgrade for Alonso at this weekend's race at Monza.
As the Spaniard had already used more than his permitted number of engine parts, it means an automatic penalty.
The idea is to ensure Alonso is in a strong position for the following race in Singapore, which favours McLaren.
Honda has not admitted to the plan, saying it has not yet decided on its engine policy for Monza, but BBC Sport has confirmed the strategy with team insiders.
It is not yet clear whether the engine Alonso will use at Monza is the 'Phase Four' specification that Honda had initially planned for Belgium.
It was not ready in time, so the company introduced an interim spec known as the 'Phase 3.5', which featured improvements to the induction system that Honda said equated to a lap-time gain of about 0.1secs.
But the Honda still lags a reputed 80bhp on the customer Mercedes engines used by Williams and Force India.
Monza is the track where engine performance is most important in terms of overall lap time, so it is inevitably going to be a difficult race for McLaren, whose Honda engine is the least powerful on the grid.
By contrast, tight and twisty Singapore is a race where the high quality of McLaren's chassis can come to the fore and the team are expecting a decent points score.
Alonso finished sixth at the Hungarian Grand Prix at the end of July, held on a similarly low power-sensitivity track.
The 36-year-old two-time champion hinted at the plan to give him a new engine in Monza when speaking after qualifying in Belgium last weekend.
There, his team-mate Stoffel Vandoorne helped him by providing a 'tow' on the straights to minimise the Honda's power deficit as much as possible.
Although Alonso also 'towed' Vandoorne in the first part of qualifying, the Belgian's performance in second qualifying was compromised to benefit Alonso because Vandoorne already had 60 places of grid penalties, 55 of which were for engine changes.
Alonso said: "We had it planned. Next week it will be the other way around because it's my turn. We were trying to take advantage of the penalties, we have to find a positive and try to do the best for the team."
F1 engine rules dictate that each driver can only use four of the six constituent parts that make up an engine during a season.
Alonso has already used six internal combustion engines and MGU-Ks, the part that recovers energy from the rear axle, and eight turbochargers and MGU-Hs, the part that recovers energy from the turbo.


The White House has acknowledged the need for additional "constraints" on US intelligence gathering, amid claims of eavesdropping on allies.

Spokesman Jay Carney said an ongoing White House intelligence policy review would account for "privacy concerns".
Spain is the latest of several countries reported to have been the target of US collection of phone data.
A top Democrat in the Senate has said its intelligence panel will undertake a "major review" of US spying programmes.
Senator Dianne Feinstein said she was "totally opposed" to the National Security Agency's (NSA) intelligence gathering on leaders of US allies.
An EU delegate in Washington described the row as "a breakdown of trust".
On Monday Mr Carney, US President Barack Obama's spokesman, told reporters the administration "recognise[s] there needs to be additional constraints on how we gather and use intelligence".
He said the US did not use its intelligence gathering capabilities for the purpose of promoting its economic interests, and that Mr Obama was committed to ensuring "that we are collecting information not just because we can, but because we should, because we need it for our security".
"We also need to ensure that our intelligence resources are most effectively supporting our foreign policy and national security objectives, that we are more effectively weighing the risks and rewards of our activities," he said.
An across-the-board review of US intelligence resources, currently under way, is also expected to assist the administration in "properly accounting for both the security of our citizens and our allies and the privacy concerns shared by Americans and citizens around the world", Mr Carney added.
Mr Carney and Mr Obama have not commented on specific allegations that the US eavesdropped on international allies, including tapping the phones of foreign officials.
Earlier on Monday, representatives from the European Parliament's Committee on Civil Liberties, Justice and Home Affairs spoke to members of the US Congress about the alleged US spying on European leaders and citizens.
"We wanted to transmit to them first that this mass surveillance of EU citizens is a genuine concern," British Labour MEP Claude Moraes, a member of the delegation, told the BBC after the meetings.
But Mr Moraes said he and his fellow delegates were unsatisfied with the "stock" responses from US officials on the issue.
"They're giving us answers, but not the answers we want," he said. "We're getting a bit tired of this, 'Well, spying has always existed.'"
Spain has also urged the US to give details of any eavesdropping, amid reports the US National Security Agency (NSA) monitored 60 million Spanish telephone calls in a month.
The latest allegation, published by Spain's El Mundo newspaper, is that the NSA tracked tens of millions of phone calls, texts and emails of Spanish citizens, in December 2012 and January 2013. The monitoring allegedly peaked on 11 December.
Minister for European Affairs of Spain Inigo Mendez de Vigo called the allegations, if true, "inappropriate and unacceptable".
The allegations of US surveillance on international allies stemmed from documents leaked by fugitive ex-US intelligence contractor Edward Snowden, now living in Russia.
German Chancellor Angela Merkel is also sending intelligence officials to Washington to demand answers to claims that her phones were tapped.
Spying scandal: For 'five eyes' only?
German media reported that the US had bugged Ms Merkel's phone for more than a decade - and that the surveillance only ended a few months ago.
The German government hoped that trust between the two countries could be restored, a spokesman told a news conference in Berlin.
"It would be disturbing if these suspicions turned out to be true. But Germany and the United States can solve this problem together," Steffen Seibert said.
Senator Feinstein, the chair of the Senate intelligence panel, has previously expressed support for US intelligence programmes, but said in light of the Merkel revelations, her committee needed to know more.
"It is abundantly clear that a total review of all intelligence programmes is necessary so that members of the Senate Intelligence Committee are fully informed as to what is actually being carried out by the intelligence community," she said in a statement.
"It is my understanding that President Obama was not aware Chancellor Merkel's communications were being collected since 2002. That is a big problem," she said.
Meanwhile, a Japanese news agency reported the NSA asked the Japanese government in 2011 to help it monitor fibre-optic cables carrying personal data through Japan, to the Asia-Pacific region.
The reports, carried by Kyodo, say that this was intended to allow the US to spy on China, but that Japanese officials refused, citing legal restrictions and a shortage of personnel.


Google will let publishers ask people who use ad-blockers to either enable advertising or make a payment to view content without ads.

"Funding Choices" will roll out first in North America, UK, Germany, Australia and New Zealand, Google said in a blog.
Google is also working on an ad-blocker of its own, which will function in its Chrome browser.
That will block specific adverts that do not meet Google's standards.
Ad blocking programs are designed to protect consumers from intrusive web ads that slow down browsers and vacuum up personal data.
Ad-blockers take "a big toll" on publishers and producers who rely on advertising revenue, said Sridhar Ramaswamy, Google's senior vice-president in Ads and Commerce.
"We believe these changes will ensure all content creators, big and small, can continue to have a sustainable way to fund their work with online advertising," he wrote.
Google is part of the Coalition for Better Ads, a group which also includes News Corp, Facebook and Unilever, and is dedicated to "improving users' experience" of online advertising.
Recent figures from the Internet Advertising Bureau (IAB) suggested that 22% of UK adults use an ad-blocking service online.
In 2016 the service Ad Blocker Plus claimed to have more than 100 million active users worldwide.


Plymouth Argyle must wait for promotion from League Two after drawing against Portsmouth at Fratton Park.

Argyle's Jake Jervis headed in Gary Sawyer's cross for a 12th-minute lead.
Third-placed Pompey levelled when Gary Roberts latched on to Luke McCormack's fumble from Kyle Bennett's cross.
Luton's draw with Leyton Orient left Plymouth 11 points clear of fourth place with four games remaining, but a win for Derek Adams' side against Newport will secure promotion.
In the so called Dockyard derby, ex-Portsmouth forward Jervis nodded in his 11th goal of the season in the first half and winger Matty Kennedy should have doubled the lead when he fired into the side netting after a mazy run.
The Pilgrims lost in the League Two play-offs last season but are still on course to secure promotion, along with leaders Doncaster who are already up, with four games to spare.
Pompey had more possession and chances throughout the game until their equaliser and sit four points beyond Plymouth, eight points clear of the chasing play-off teams.
