President Barack Obama has paid tribute to US forces for an operation in northern Iraq that helped "break a siege" and rescue tens of thousands of displaced people.

Mr Obama said the situation on Mount Sinjar had greatly improved.
Many of those displaced had now left the mountain and further rescue operations were not envisaged, he said.
However, Mr Obama said the US would continue air strikes against the Islamic State (IS) rebel group.
Iraqi and Kurdish forces who were fighting IS would also continue to receive US military assistance, Mr Obama said.
The jihadist militants, formerly known as Isis, seized a large band of territory across northern Iraq and Syria this summer.
The United Nations estimates that 1.2 million Iraqis have been internally displaced by the latest violence.
Speaking in the US, the president re-emphasised the need for Iraqis to find a political solution to the crisis, describing the prospect of a new and inclusive government, led by Haider al-Abadi, as an "enormous opportunity".
"He still has a challenging task in putting a government together, but we are modestly hopeful that the... situation is moving in the right direction," Mr Obama said.
Mr Abadi, a deputy speaker of parliament, has been asked by the Iraqi president to form a new government.
Current Prime Minister Nouri Maliki, whose coalition won the most seats in April's election, had vowed to contest the move in court, describing it as a violation of the constitution.
However, reports coming out of Baghdad on Thursday evening, and attributed to MPs, said Mr Maliki was to address the nation, announcing he would stand aside in favour of Mr Abadi.
Iraq's Foreign Minister Hoshyar Zebari said Mr Maliki had no choice but to "accept the wishes of the majority of Iraqis".
Mr Zebari, who served under the prime minister until last month, also dismissed fears that Iraq could fall apart, saying the Kurdish leadership had "decided to be part of the new government".
Iraq's military response to a rapid advance by IS has been hampered by political chaos in Baghdad.
On 29 June, the militant group said it had created a caliphate, or Islamic state, stretching from Aleppo in Syria to the province of Diyala in Iraq.
It has declared Iraq a "Level 3 Emergency", its highest ranking of a crisis. The move should enable more resources to be directed in support of humanitarian efforts.
The UN had earlier estimated that tens of thousands of people, mostly from the Christian and Yazidi religious minorities, were besieged on the mountain after being forced to flee their homes.
But US forces sent to Mt Sinjar found fewer people than expected - partly because thousands had left the mountain each night over the past days.
Kurdish officials told the BBC's Frank Gardner that some 150,000 refugees had ended up in the northern city of Dohuk, where the local population was struggling to feed them.
Hamad, a Yazidi who managed to escape with his family, told the BBC that his mother had died during the long journey to Dohuk.
"There was no food. We were exhausted after a lot of walking and climbing high, steep roads," he said, adding that his mother eventually said she could go no further.
"We refused to leave without her. After a few hours of thirst, hunger and exhaustion, she fell and passed away."


The newly retired Jessica Ennis-Hill is one of Britain's greatest athletes, says former world 1500m champion Steve Cram.

The 30-year-old won heptathlon gold at London 2012 and added a silver medal at the Rio Olympics.
Ennis-Hill also won the World Championships in 2009 and again in 2015, just 13 months after the birth of her first child, Reggie.

Cram told the BBC: "She fully deserves to be called an all-time great."
And former Olympic relay gold medallist Darren Campbell called her achievements "mind-blowing".
Ennis-Hill's heptathlon gold was one of the the iconic moments at London 2012 and occurred on 'Super Saturday', when British trio Ennis-Hill, Greg Rutherford and Mo Farah all won gold with 44 minutes.
The Sheffield athlete announced her retirement on social media on Thursday, writing: "Retiring now is right. I've always said I wanted to leave on a high and have no regrets and I can truly say that."
Former Olympic gold medallist Campbell told Radio 5 live: "It's a sad day but it's also a day where we should celebrate what a phenomenal athlete Jessica Ennis-Hill was. She gave so much to sport, achieved so much, had so many inspirational moments throughout her career.
"She is a normal girl, but she has achieved things that are exceptional and mind-blowing. It is only when you sit back and reflect that you realise how mind-blowing they are."

Labour in Wales will not "fall into the trap of arguing with ourselves", First Minister Carwyn Jones has told the BBC.

His comment came amid the latest round of party in-fighting at Westminster.
Unite union boss Len McCluskey has rejected claims by Labour deputy leader Tom Watson that it is plotting to help a left-wing group take over the party.
Mr Jones said people do not want parties "spending more time arguing with each other" than working for the people they were elected to represent.
Mr Watson has accused Unite of planning to fund activist group Momentum, which he said could "destroy" Labour, a claims Mr McCluskey called "a complete fabrication".
Meanwhile, Labour leader Jeremy Corbyn faced hecklers as he urged his MPs to unite at an angry Monday night meeting.
Speaking to BBC Radio Wales on Tuesday, Mr Jones said: "I'm not going to pretend to you that things are going well in Westminster - clearly they're not.
"We in Welsh Labour fought an election last year, we're very united as a party and we're absolutely focused on delivering for the people of Wales," he told the Good Morning Wales programme.
"What people don't want to see in any political party is a political party that spends more time arguing with each other than actually delivering for the people that it's elected to represent.
"We're certainly not going to fall into the trap of arguing with ourselves," Mr Jones said of Welsh Labour.
"We're here to do a job and we intend to stick to it."
In December, the first minister said Mr Corbyn needed to "ruthless focus on the things that matter to ordinary people", days after attacking Mr Corbyn's position on immigration.


A huge scrapyard blaze involving about 30 cars has been brought under control.

The "severe fire" broke out in Wolverhampton at about 19:55 BST on Friday and six fire engines were sent to the scene.
The flames at the metal recycling yard at Bilston Road in Monmore Green were prevented from spreading to surrounding buildings, West Midlands Fire Service said.
The blaze was under control by 03:30 and the cause is being investigated.


A Serbian inquiry has found that the president's jet went into a sudden plunge on a flight to Rome last week when the co-pilot tried to mop up a coffee spill.

President Tomislav Nikolic and other passengers were reportedly thrown around the Falcon 50's cabin before the captain managed to regain control.
Coffee was spilt on the control panel and the co-pilot mistakenly disengaged the autopilot when trying to mop it up.
The jet later turned back to Belgrade.
President Nikolic had been heading to Rome on 17 April for a meeting with Pope Francis.
Co-pilot Bojan Zoric has been suspended after the inquiry found he had "accidentally activated the emergency switch". That caused the plane to plunge from a height of 34,000 feet (10,303m).
One of the Falcon's three engines shut down because of the sudden drop in altitude, but it was quickly restarted.


Stormont departments have used anti-terror legislation hundreds of times to spy on benefits cheats and insurance fraudsters over the past five years.

The Regulation of Investigatory Powers Act (Ripa) was passed 17 years ago to prevent terrorism and organised crime.
Stormont's Department for Communities told the Irish News it had used Ripa 591 times since April 2012.
A spokeswoman said the powers were only used "where necessary and within the parameters set down in law".
The law, dubbed the "snoopers' charter", has been used to detect littering and petty crime.
The Irish News obtained the figures though a Freedom of Information (FOI) request.
It reported the department had used the law to investigate fraudulent benefit claims, including exaggerated disabilities and those who apply for job seekers' allowance while in work.
The Irish News also reported that Stormont's Department for Infrastructure requested Ripa powers 132 times in the same period.
Since 2000, Ripa has been used by certain authorities to access the private phone and email records of people who are suspected of involvement in crime and anti-social behaviour.
Critics claimed the controversial law threatened civil liberties, but the government argued the measures were necessary to protect the public.
Confirming the figures, a spokeswoman for the Department for Communities told the BBC: "The powers within the Regulation of Investigatory Powers Act 2000 are used for the purposes of preventing and detecting crime and the investigation and prosecution of benefit fraud cases.
"The use of any investigatory powers is strictly controlled and applied proportionately, only where necessary and within the parameters set down in law."
A spokesperson for the Department for Infrastructure told the Irish News that the Driver and Vehicle Agency primarily used Ripa to prevent personal injury compensation fraud and offences involving illegal taxis and buses.
It told BBC News NI it had not used any Ripa powers since May 2016.
Ripa has been recently overhauled and incorporated in the wide-ranging Investigatory Powers Act 2016.
The bill was granted Royal Assent in November and, for the first time, it allows the authorities to access internet browsing records.


A prankster who performed weight-lifting moves on a car park barrier is being hunted by police.

The man was caught on CCTV repeatedly lifting the exit barrier at Nottingham railway station up and down, causing "substantial damage".
British Transport Police officers are hoping to track down the man and have asked anyone who recognises him to come forward.
The stunt happened shortly before 19:00 GMT on Saturday 14 March.


The crew of the Derry-Londonderry-Doire have taken second place in a closely fought finish to this year's Clipper Round the World Yacht Race.

It was a close finish, with the Derry team just four points behind winner LMAX Exchange, another UK-based crew.
Some of those involved in the competition have spent 11 months at sea, as the race spans six continents.
Thousands of spectators lined the banks of the Thames in London on Saturday as the teams celebrated the final result.
Many of the 690 competitors are amateurs and some of them had little or no previous sailing experience before they embarked on the global challenge last August.
The organisers said this year's entrants "endured some of the most extreme conditions ever experienced in the event's 20-year history".
The amateur sailors had to cope with hurricane force winds, giant waves, freezing conditions, injuries and for the IchorCoal team - a double tragedy.
IchorCoal crewman Andrew Ashman was fatally injured by the yacht's boom last September, and Sarah Young was swept overboard in the Pacific Ocean in April.
Clipper Race founder Sir Robin Knox-Johnston, who was first person to sail solo non-stop around the world, acknowledged that this year's event was "extremely tough".
"The conditions encountered in the Pacific were the worst we've seen in 20 years of running the race," he said.
"I am proud of all of the crew; they have taken on all the world's most challenging oceans and have been very resilient.
"They should be justly proud of themselves - whether crossing a single ocean or circumnavigating the entire planet. It is a remarkable achievement."
The competition is spread over 14 individually scored races.
The Derry-Londonderry-Doire won four of the individual races and finished with a total of 148 points.
LMAX Exchange was crowned the overall winner with 152 points.
The victorious yacht is owned by the British financial technology firm LMAX Exchange, whose chief executive, David Mercer, is from Belfast.
He said: "I'd like to thank all 58 crew who contributed to this herculean effort with special mention to our eight round the worlders - the glue that kept our team bond strong throughout."
The final results were:


Washington has expelled two Cuban diplomats after US embassy staff in Havana suffered mysterious physical symptoms, the US state department said.

It was not immediately clear what had happened, with spokeswoman Heather Nauert saying there were no "definitive answers about the source or cause".
But Ms Nauert refused to be drawn further on what the symptoms were.
But one source told the Associated Press news agency the symptoms reported included hearing loss.
It was suggested the hearing loss could have been caused by some kind of sonic device placed outside the diplomats' homes, emitting inaudible sound waves that can cause deafness.
Staff began complaining of the strange symptoms late last year, Ms Nauert said.
While they were not life-threatening, she revealed a number of people had been brought home to the US as a result.
Ms Nauert said the government was taking it "very seriously, and there is an investigation currently under way".
It is understood that the two expelled Cuban diplomats left Washington DC in May, the BBC's Will Grant reports from Havana.
So far, their government has not responded to the reports.
Washington and Havana only re-established ties in 2015, following 50 years of hostilities between the two countries.


Brighton & Hove Albion have made their first signing since winning promotion to the Premier League, bringing in Pascal Gross from FC Ingolstadt 04.

The 25-year-old midfielder, who has agreed a four-year contract, will join for an undisclosed fee on 10 June.
He has made 32 appearances in the German Bundesliga this season.
"We are delighted that Pascal has opted to sign for us, amid interest from a number of clubs from the Premier League and Europe," said boss Chris Hughton.
"He offers something different to our existing midfielders, as an attacking midfielder in a more advanced position, operating behind the forward line."
Gross, who has scored four times this season as Ingolstadt were relegated, has created more chances than any other player in the Bundesliga this season.

Families of workers affected by asbestos related cancers have called for better screening for the condition.

Illnesses associated with working in the construction industry are thought to kill more than 4,000 people across the UK every year.
Experts have warned that 2015 will see a peak in numbers.
The Clydeside Action on Asbestos charity said early detection would improve the life expectancy of patients.
Lynsey Innes, 40, told BBC Scotland how her father Gordon Roberts died of mesothelioma - a form of cancer most commonly caused by exposure to asbestos.
Mr Roberts had spent his working like as a joiner before retiring at the age of 62. He kept fit by swimming.
He had difficulty breathing last summer and eventually went to the doctor, where an X-ray examination found mesothelioma.
Mr Roberts was told he had only between nine and 12 months to live, and died at Easter of this year. He was 70.
Ms Innes said her uncle, who had been a plumber, also died of mesothelioma after discovering pains in his shoulder.
She said: "It was just a simple x-ray that picked up my dad's cancer. It doesn't cost a lot of money to give an X-ray to somebody. (Carrying out screening) within a certain generation, over a certain period of time, would be ample to try and catch it at an early stage.
"If you catch it at an earlier stage the chemotherapy may shrink the tumour, you may then not get nine to 12 months - you can get up to five years."
At its annual general meeting on Saturday, Clydeside Action on Asbestos - the biggest asbestos charity in Scotland - called for more investment in screening, either through routine X-rays or a simple blood test that would detect illnesses.
Phyllis Craig, the charity's chairwoman, said catching the disease at the earlier possible opportunity would allow patients to "start making plans for their life and their families and so forth, but also to receive any form of treatment that may be available."
A Scottish government spokesman said it took advice on national screening programmes from the National Screening Committee, and screening programmes are only introduced after a detailed assessment of clinical and cost effectiveness and public health benefit.
He added: "The National Screening Committee has not considered screening for asbestos exposure."
He encouraged anyone who has symptoms such as difficulty breathing, shortness of breath, coughing and chest pains and who has a history of working in occupations or industries associated with asbestos exposure to contact their GP.


Neil Doncaster believes cross-border competitions will become a widespread feature across European football.

Northern Irish and Welsh teams featured in the draw for the last 16 of the Scottish Challenge Cup.
And Scottish Professional Football League chief executive Doncaster says member clubs should be "open-minded" to playing teams outside their borders.
"Over the next few years we're going to see the whole question of cross-border competition coming from Europe," he said.
Football League clubs in England are currently considering proposals to introduce a fifth division for the 2019-20 season, and which clubs to invite to the new set-up, including the possibility of involving Celtic and Rangers.
Proposals for a cross-border Atlantic League continue to be discussed, while other regional leagues in Europe have also been mooted.
In the fourth round of the Challenge Cup, Irish Premiership leaders Crusaders will host Livingston and Linfield visit Queen of the South.
Welsh Premier League leaders the New Saints visit Forfar Athletic while Bala Town welcome Alloa Athletic.
"There seems to be a willingness from Uefa to see cross-border competition develop," Doncaster explained.
"The Irn-Bru [Challenge] Cup and the innovations we've seen this year demonstrate that we're somewhat ahead of that game.
"Be in no doubt, cross-border competition is going to feature increasingly on the European football landscape. To have tried it out and had it endorsed by Uefa in a UK-football context is a positive development.
"We have to have an open mind about anything that is going to aid the game in Scotland and be of benefit to all 42 member clubs."
Any proposals for senior Scottish clubs playing outside the SPFL pyramid would need to be ratified by league clubs and governing bodies and may involve colt teams continuing to play in Scotland's senior leagues.
However, former Celtic and Arsenal striker John Hartson believes there would be a financial impact on other Scottish Premiership clubs if Rangers and Celtic played in one or more other countries.
He said: "You've got all the politics, do the chairmen and owners of the English league want Celtic and Rangers, does Scotland want to lose them?
"Look at the revenue and the finances, the crowds, especially now with Rangers back in the top flight. Teams like Motherwell, Dundee, they're very reliant on Celtic and Rangers, especially with the feel-good factor back now and playing in front of full houses.
"If you watch Motherwell most weeks there are 4,500 there, when Celtic go there are 18,000 people there. In terms of what Celtic and Rangers bring to the Scottish leagues, you can't put a price on that.
"Scottish football suffered when Rangers were out [of the top flight], so they'll suffer badly if both teams are out."


A number of George Best commemorative banknotes have been stolen in a robbery in County Londonderry.

The burglary took place at a house in The Beeches area of Drumahoe on 31 March. It happened sometime between 08:00 and 17:25 BST.
The limited edition notes were released in 2006, marking the first anniversary of the Manchester United football legend's death.
A watch was also taken in the burglary.
Police have appealed for information.


A day after Pakistan's Prime Minister Nawaz Sharif announced the end of a seven-year moratorium on executions last year, Sabir Masih found his house surrounded by the paparazzi in Lahore.

The hangman had encounters with reporters and cameramen before, and would have been happy to share his views on the resumption of hangings on camera, but he was running out of time.
"I had to reach Faisalabad by the evening of 18 December because they had lined up two convicts for hanging early next morning," he recalls.
So he threw some clothes in a small shoulder bag, then put on the clothes of his 17-year-old sister, covered his face in a veil and walked right past the TV broadcast vans outside his house to reach the bus stop.
Just around that time, some 170km (105 miles) to the west, security forces in Faisalabad were taking the two convicts from the city's central jail, which has no gallows, to the district jail.
These were no ordinary convicts.
Mohammad Aqeel, alias Dr Usman, had led the audacious 2009 assault on army headquarters in Rawalpindi in which 20 people were killed, while Arshad Mehmood had been convicted for a 2003 assassination attempt on then-President Pervez Musharraf.
Both were former soldiers and members of Pakistan's feared home-grown militant networks.
Meanwhile, Mr Masih had to produce his official executioner's ID several times to get past the roadblocks the army and police had set up to pre-empt any revenge strikes by militants.
The next day, Aqeel and Mehmood became the first men to be executed in Pakistan in seven years, and it was the 32-year-old Mr Masih who was the hangman.
There are about 8,000 people on death row in Pakistan, more than any other country in the world, and since December Pakistan has put to death about 200 of them - some convicted of terrorist offences, others of murder.
Some of the cases have raised concerns over justice. On Tuesday a 23-year-old man, Shafqat Hussain, was executed for a child murder he denied committing.
His lawyers argued to the end that he had been a boy at the time of the murder and a confession was tortured out of him in custody.
Since the moratorium was lifted, Mr Masih says he has hanged close to 60 people in more than half a dozen jails in Punjab province. (He was not involved in the execution of Shafqat Hussain, who was put to death in Karachi.)
Overall, he believes he has executed more than 200 men since 2007, a claim he makes without a hint of remorse in his voice.
This is probably because he belongs to a family of hangmen - the Pakistani equivalent of the Pierrepoints of Britain, Sansons of France, or Mammu Jallad's family in India.
Like most executioners from the times of the British Raj, Mr Masih is a Christian. His surname is the local name for Jesus, and is a common surname among Christians of the sub-continent.
He has sunken and heavily wrinkled eyes, teeth turned yellow from chewing tobacco and a heavy stammer in his speech, but a lean, 5ft 10in frame and bold facial features.
"Hanging is my family profession," he says. "My father was a hangman, and his father was a hangman, and his father and grandfather before him - since the times of the East India Company."
Perhaps his most famous ancestor is his grandfather's brother, Tara Masih, the man who hanged Pakistan's first elected prime minister, Zulfikar Ali Bhutto, in 1979.
Tara Masih had to be flown from Bahawalpur to Lahore for the hanging because the executioner in Lahore, Sadiq Masih, Tara's nephew and Sabir's father, excused himself from hanging the popular leader.
Sabir also says that his grandfather, Kala Masih, hanged Bhagat Singh, a socialist revolutionary and hero of the Indian freedom movement, in 1931.
But there's a counter claim from members of Mammu Jallad's family in India who say Bhagat Singh was hanged by Ram Rakha, Mammu's grandfather.
With this kind of family history, Sabir Masih is dogged by journalists looking for insight into his job, with questions like, do you get sleep the night before you are scheduled to hang a convict? Do you get nightmares afterwards? What did you feel when you hanged your first victim? How do your family and friends view your job?
"I feel nothing. It's a family thing. My father taught me how to tie the hangman's knot, how many coils etcetera, and he took me along to witness some hangings around the time when I was being recruited."
His first solo hanging was in July 2007.
"The only thing that made me nervous was to get the knot right, but the deputy chief of the jail told me not to worry.
"He made me tie and untie the knot a number of times before the convict was brought to the gallows. When the jailer waved his hand for me to pull the lever, I was focused on him, and didn't see the condemned man fall through the trapdoor."
It's more or less the same now.
The condemned prisoner "is read the charges by a magistrate, asked to bathe and offer prayers if he wants, and then walked to the gallows by the jail guards.
"My only concern is to prepare him at least three minutes before the time of hanging. So I remove his shoes, put a hood on his face, tie his hands and feet, put the noose around his neck, make sure the knot is placed below his left ear, and then wait for the jailer's signal to pull the lever."
There is no pre-or post-hanging psychological counselling for hangmen, and no limit to the number of hangings one executioner may perform before he is given a break.
Mr Masih says he doesn't need either.


Police have condemned a wave of "copycat criminal activity" across London in a second night of looting and disorder following riots in Tottenham.

More than 100 people have been arrested as officers were attacked, police vehicles damaged and shops looted.
Disorder spread to Enfield, Walthamstow and Waltham Forest in north London and to Brixton in the south of the city.
Home Secretary Teresa May has cut short her holiday to return to the UK following the disorder.
Some 35 officers have been injured over the two nights of rioting.
Three officers were hurt when a vehicle hit them as they tried to make an arrest in Waltham Forest, east London.
Clashes broke out in Enfield, north London, on Sunday evening where shop windows were smashed and a police car damaged.
There have been reports of a gang of up to 200 youths looting shops and charging police in Coldharbour Lane and the High Street in Brixton, south London.
Metropolitan Police Commander Adrian Hanstock said: "This is not groups of people acting on behalf of communities or with any consent.
"This is individuals who are actually attacking communities, businesses, properties and houses and actually causing a huge amount of upset and criminality."
The Met said it had dealt with several incidents of "copycat criminal activity" across the city.
These included:
Kit Malthouse, Deputy Mayor of London and Chair of the Metropolitan Police Authority, described the scenes of the last two nights as "disgusting and shocking" and said the police did a good job.
He added: "Obviously there are people in this city, sadly, who are intent on violence, who are looking for the opportunity to steal and set fire to buildings and create a sense of mayhem, whether they're anarchists or part of organised gangs or just feral youth frankly, who fancy a new pair of trainers."
Talking about the impact on the capital's image, one year ahead of the Olympic Games, he said: "It's pretty rotten for London, it does not look good.
"What we need to do over the next few months is to underline to people the fundamental truth about London which is that it is one of the safest, great big cities on earth.
"We have a low murder rate and this kind of violence is very rare."
The Home Secretary, Theresa May said: "Last night, police officers again put themselves in harm's way to protect Londoners and their property.
"Londoners have made clear that there are no excuses for violence, and I call on all members of local communities to work constructively with the police to help them bring these criminals to justice."
BBC London's Paraic O'Brien said he had witnessed widespread looting in Brixton.
He said: "They smashed a William Hill, they set bins on fire.
"And now what we're seeing as the night progresses is that replicated, sort of flashpoints all along Brixton High Street.

I saw the rioting in Tottenham on Saturday and I saw the rioting last night and it was certainly different in character.
What might have been started in Tottenham by youngsters aggrieved about what they saw as police persecution has become something very different in nature.
Last night there was a sense that the looting, and violence and disorder across London was being co-ordinated on social media.
There were people in their cars, youngsters on bicycles, moving very rapidly, leaving a trail of destruction behind them. As soon as you moved to one location they would move on to the next one.
The police were doing their best to catch up with them. You had police vehicles going backwards and forwards, blue lights flashing, riot police coming out of their vehicles.
Ten minutes later they'd get back in again and go off to the next location - essentially trying to fight the fires, metaphorically, that were spreading all over London.
"I'm standing outside Halfords on the other side of the road and they've just smashed through the doors of Halfords. They're taking bikes out the front entrance.
"I have to say, what really struck me was the small number of police officers that there actually seem to be on Brixton High Street responding to this."
Press Association photographer Lewis Whyld saw looters battle police at a Currys store in Brixton.
He said: "A couple of hundred youths were rioting and looting. Riot police went in to get them out and there was a big fight in the street.
"Youths were throwing rocks and bottles and there was a bin on fire. They used a fire extinguisher to push the police back so they could get back into Currys and continue taking things out."
Met Police Commander Christine Jones said: "Officers are shocked at the outrageous level of violence directed against them.
"At least nine officers were injured overnight in addition to the 26 injured on Saturday night."
London Fire Brigade said it had been called to a number of fires in Enfield, Brixton and Walthamstow, including a fire at a shop on Brixton Road, which is now under control.
The disorder follows rioting in Tottenham which broke out on Saturday night and continued into Sunday morning.
A peaceful protest over the fatal shooting by police on Thursday of 29-year-old Mark Duggan descended into violence later in the evening.
The unrest spread into nearby Wood Green and Tottenham Hale.
Shops were attacked and looted, 26 police officers and three others were injured and buildings and vehicles were set alight.
Tottenham Hotspur Football Club's ticket office was also damaged during the violence.
Deputy Assistant Commissioner Steve Kavanagh told the BBC Radio 4 Today programme that there were too few officers in Tottenham on Saturday night, but blamed Twitter for fuelling looting and violence, saying: "Social media and other methods have been used to organise these levels of greed and criminality."
Mr Kavanagh pledged that more officers would be on London's streets on Monday night to prevent or tackle further outbreaks.
Parts of Tottenham are still cordoned off, as officers and forensic specialists continue to examine the riot scene.
A total of 61 arrests have been made in connection with the first night of rioting. The majority were for burglary, and other offences including violent disorder, robbery, theft and handling stolen goods.
Sixteen people have been charged for offences including burglary, violent disorder and possession of a pointed or bladed weapon following the Tottenham riots.
As well as Mr Duggan, a police officer was also shot in Thursday's incident, which happened in what was called a "pre-planned" event, under Operation Trident, which investigates gun crime in London's African and Caribbean communities.
Police had stopped a minicab which Mr Duggan had been travelling in.
The violence has also affected public transport and the roads. This includes:


A man has admitted he allowed three dogs to die a "long, slow, agonising death" when he left them in a hot car.

Jonathan Theobald, 65, left Staffie-type dogs Daisy, Mitch and Rascal in a vehicle in Peterborough for about five hours on 16 June.
RSPCA inspector Justin Stubbs, the investigating officer, said they "may have slowly cooked, essentially".
At Peterborough Magistrates' Court, Theobald admitted causing unnecessary suffering by confining them in the car.
He is expected to be sentenced at a later date.
More on this and other news from Cambridgeshire
The dogs died after being left in a car on Ashbourne Road while Theobald went to a gym.
The court heard that when he returned, two of the dogs were dead. He attempted to resuscitate the third but a vet, who he had called, pronounced it dead.
The weather on the day in question was "overcast, not hot, but warm and humid", Mr Stubbs said.
The temperature ranged from 16-19C (61-66F), but humidity levels were high.
The animals would have suffered a "long, slow, agonising death", the inspector said.
"The dogs would have overheated, they would have had fits. They may have slowly cooked, essentially."
It was, he said, a "tragic accident" but leaving animals in cars for any length of time in such conditions was like "putting your dog through torture".
Speaking before his court appearance, Theobald, who was visibly distressed, said: "I am so sorry. I am appalled by what happened.
"I have shed a lot of tears since then."
"I understand the RSPCA has a job to do and I don't want this to happen again."
Theobald, of Lincoln Road, Peterborough, was charged under Section 4 of the Animal Welfare Act 2006.
In court he admitted one count of causing unnecessary suffering to the dogs by confining them in an environment which was detrimental to their well-being and led to their death.


Global per capita fish consumption has hit a record high, passing the 20kg per year mark for the first time, United Nations data has shown.

The Food and Agriculture Organization (FAO) report said it was the result of improved aquaculture and reduced waste.
It added that people, for the first time on record, were now consuming more farmed fish than wild-caught fish.
However, the report's authors warn that marine natural resources continue to be overharvested at unsustainable levels.
The data has been published in the FAO's biennial State of the World's Fisheries and Aquaculture (Sofia) report.
Manuel Barange, director of FAO Fisheries and Aquaculture Policy and Resources, welcomed the fact that global per capita fish consumption has passed the 20kg per year threshold.
"I personally think this is a very good thing because it shows that over the past five decades, fisheries supply - which combines aquaculture, inland fisheries and marine fisheries - has outpaced human population growth very significantly," he said.
"This is very significant because fisheries have a very much smaller footprint than other main sources of animal protein," he told BBC News.
"Fish is six times more efficient at converting feed than cattle, and four times more efficient than pork. Therefore increasing the consumption of fish is good for food security.
The growth in aquaculture has been identified as a key driver in boosting the global per capita consumption levels of fish. In the 1960s, the figure was an average of 9.9kg; in the 1990s, it was in the region of 14.4kg.
Mr Barange said the global aquaculture sector provided 74 million tonnes of fish products. Half of this production came from "non-feed" sources, which were species that did not require additional feeding in order to grow, he explained.
"That is quite important because when aquaculture started to develop as an industry, there were concerns that it would require feeding from, essentially, marine fish turned into fish meal," Mr Barange told BBC News.
"That in itself, the concern was, would be enough to undermine marine fisheries. But, actually, half of the aquaculture production does not need feeding at all."
He added that another factor for the boost in the per capita figure was a result of more fish products being used for human consumption, rather than being diverted to feed animals etc.
"In the 1960s, we used to eat about 67% of the fish we caught and cultured. Currently, it is about 87%," he said.
"Improving consumption, improving the value chain and reducing losses, combined with aquaculture growth, is what has allowed us to reach this milestone."
Mr Barange said that the FAO was working with its member countries to develop guidelines for sustainable aquaculture that they can implement in their national policies.
"In the initial boom of aquaculture production, there was little attention paid to the underlying environmental impacts. This has improved over time," he observed.
"Clearly, there are still cases where aquaculture is causing damage to habitats but there are a large number of aquaculture industries that are developing in ways that are seen as sustainable."
While there were positive signs from the global aquaculture sector, the FAO Sofia report showed that life beneath the waves was not improving overall.
"Based on FAO's analysis of assessed commercial fish stocks, the share of fish stocks within biologically sustainable levels decreased from 90% in 1974 to 68.6% in 2013. Thus, 31.4% of fish stocks were estimated as fished at a biologically unsustainable level and therefore overfished," it reported.
Mr Barange said it was vital to continue to push for sustainability in the fisheries and aquaculture sector because it was an important source of employment and trade.
"There are about 57 million people that are engaged primarily in fishing; 80% of them are in Asia," he said.
"About 12% of the world's population rely on the fishing industry for their livelihoods. The majority of these people are in the developing world."
He added that trade in fish had grown exponentially in recent decades: "In 1976, fish exports amounted to only US $8bn. In 2014, it had reach US $148bn.
"Of this total, US $80bn was directly improving the finances of developing countries. That amount is higher than the net trade revenues of meat, tobacco, rice and sugar combined.
"The role that fish and fisheries play in economies and labour markets, particularly in the developing world, is very often understated. But it is extremely important.
"It is in this context that we want to improve the sustainability of these resources because so many of the poorest people on Earth depend on those resources."

Scotland's newest hospital is the worst-performing for patient waiting times in the latest weekly accident and emergency (A&E) figures.

They show that the £842m South Glasgow University Hospital saw 1,420 A&E patients in the week ending 31 May.
Of these, 238 waited for longer than the four-hour target for treatment with 20 waiting longer than eight hours.
The 83.2% performance rate is the lowest of Scotland's 31 A&E units and well below the 95% government target.
The 1,109-bed hospital, which began taking patients in April, was built on the site of the Southern General and is one of the largest acute hospitals in the UK.
The new campus replaces the Royal Hospital for Sick Kids at Yorkhill, the Southern General Hospital, Western and Victoria infirmaries and Mansionhouse Unit.
NHS Greater Glasgow and Clyde had the lowest performance rate for any health board, with 88.5% of patients seen within four hours.
The health board also had the highest number of people attending A&E at 6,670.
Throughout Scotland, overall performance improved slightly, with a total of 92.6% of people treated within four hours, up from 92% in the previous week.
The figures show 156 patients waited more than eight hours and 21 patients waited more than 12 hours.
Health Secretary Shona Robison said: "Today's figures show that our NHS staff are continuing to work hard towards delivering a first-class service for Scotland.
"This week has seen an improvement in waiting times but weekly publications will continue to show fluctuations in these figures.
"What is important now is that health boards focus on sustaining the reduced waiting times we have recently seen and make more, sustainable progress towards meeting our world-leading targets."
The Scottish government has put in place an action plan to improve unscheduled emergency care and Ms Robison said £100m had been invested to tackle delayed discharges, otherwise known as bed blocking.
Reacting to the A&E figures, Labour's Jenny Marra said it was clear that the new hospital could not cope with patient numbers.
She added: "We want to see more people treated and supported at home and in the community but the failure to resource GPs and care workers to provide this is driving patients to a hospital which is being overwhelmed by demand.
"Until we see the shift to community care that the SNP government promised, many hospitals across the country will have to ask patients to wait longer and longer for treatment and targets will continue to be missed."


Welsh hooker Edd Shervington has re-joined Wasps on a three-month contract.

The Premiership club have re-signed the 31-year-old to provide cover, with Tom Cruse and George Edgson both injured.
Shervington came out of retirement to join Bristol in October, but did not make a first-team appearance.
The former Worcester Warriors, Ospreys and Leinster player was previously at Wasps for two seasons, making 32 appearances for the club between 2014 and his initial retirement in May.


A leading manufacturing firm has said it was the source of a big pollution spill off the County Antrim coast.

Caterpillar Northern Ireland said the diesel had got into a storm drain which runs to the sea off Larne.
It is believed around 40,000 litres of fuel was involved. It was part of a bigger spill, some of which was contained on site.
The incident is being investigated by the Northern Ireland Environment Agency (NIEA).
People involved in a regatta off the County Antrim coast on Saturday reported a long diesel slick and heavy fumes.
It is believed the slick spread several miles north of Larne harbour.
Caterpillar said it had reported the incident when it was discovered.
It said it had also employed an environmental contractor to help with the clean up.
A spokesman for the firm told the BBC: "A control unit that manages the quantity of diesel entering a test tank failed.
"We are carrying out our own investigation to fully understand how this happened and to implement a permanent remedy."
The NIEA has taken samples with a view to enforcement.
East Antrim MLA Oliver McMullan, from Sinn FÃ©in, called for a full investigation.
"This major diesel spillage off the coast of Larne is a cause for serious concern in the East Antrim area.
"The company behind the spillage have said it was responsible but a number of questions still have to be answered.
"We need to know how this diesel got into storm drains and ended up in the sea," he added.
Caterpillar Northern Ireland mainly makes diesel generators at its Larne facility.


The County Antrim bus manufacturing firm, Wrightbus Group, more than tripled its pre-tax profits to £14.5m in 2014.

The profit was achieved on turnover of £297m in the 15 months to December 2014.
The directors' report said the figures showed a "substantial improvement" in the Ballymena-based group's performance.
It added that the outlook for 2015 was positive with a strong UK order book.
The business now employs more than 1,500 people, mainly in Ballymena.
Meanwhile, the Wright family's company, which ultimately owns the business, made charitable donations of £4.4m in the last year.
The donation from the Cornerstone Group was described as funds for "Christian, evangelical and other charitable activities".


Up to 16% of hydraulically fractured oil and gas wells spill liquids every year, according to new research from US scientists.

They found that there had been 6,600 releases from these fracked wells over a ten-year period in four states.
The biggest problems were reported in oil-rich North Dakota where 67% of the spills were recorded.
The largest spill recorded involved 100,000 litres of fluid with most related to storing and moving liquids.
The rapid growth in the extraction of oil and gas from unconventional sources in the US has had a massive impact on the production and consumption of energy over the past ten years.
The key to this expansion has been the use of hydraulic fracturing, the process of injecting fluids with chemical additives under pressure to crack underground rock and release the trapped resources.
However, environmental campaigners have long been troubled by the potential for this process to contaminate water supplies and the environment through leaks and spills.
A study carried out by the US Environment Protection Agency on fracking in eight states between 2006 and 2012 concluded that 457 spills had occurred.
But this new study, while limited to just four states with adequate data, suggests the level of spills is much higher. The researchers found 6,648 spills between 2005 and 2014.
"The EPA just looked at spills from the hydraulic fracturing process itself which is just a few days to a few weeks," lead author Dr Lauren Patterson from Duke University told BBC News.
"We're looking at spills at unconventional wells from the time of the drilling through production which could be decades."
The state reporting the highest level of spills was North Dakota, a hot bed of activity in both oil and gas recovery.
The data recorded 4,453 incidents in the state, much higher than Pennsylvania, Colorado and New Mexico.
This can be explained by reporting requirements. In North Dakota, any spill bigger than 42 US gallons has to be reported while in Colorado and New Mexico the requirement was 210 gallons.
Most of the spills occurred in the first three years of operation. Around 50% of spills were related to the storage and movement of fluids via pipelines. The underlying causes were difficult to determine because of different reporting requirements.
"The causes are quite varied," said Dr Patterson.
"Equipment failure was the greatest factor, the loading and unloading of trucks with material had a lot more human error than other places."
A surprising number of spills occurred at wells which had recorded a previous incident, over half in the case of North Dakota. This suggests that targeted inspections on these sites might have a significant impact in reducing spills.
However industry sources dispute the impact that these spill are having. They argue that very few have resulted in contamination to the environment.
"The reality is that North Dakota requires that companies report any spills that are a barrel or more, even if they never impact the environment - and the vast majority of spills have not," said Katie Brown from Energy in Depth, a body funded by petroleum producing companies.
"According to the North Dakota Department of Health, 70% of all spills in 2013 were contained on the well pad and never reached land or water."
For the authors of the study, the underlying message is that better and more uniform data collection and reporting across different states would allow the industry and environmentalists to better assess the impact of fracked wells on the environment.
"Analyses like this one are so important, to define and mitigate risk to water supplies and human health," said Kate Konschnik, another author on the paper from Harvard Law School's Environmental Policy Initiative.
"Writing state reporting rules with these factors in mind is critical, to ensure that the right data are available - and in an accessible format - for industry, states and the research community."
The study has been published in the journal, Environmental Science & Technology.

A man accused of murdering his ex-girlfriend was seen acting "strangely" the morning her body was discovered, a court has heard.

Michael Lane denies killing Shana Grice, 19, who had her throat slit and her bedroom torched.
A friend of Mr Lane, lay preacher Andrew Birks, told Lewes Crown Court he saw him shortly before she was found.
He told the jury he had waved to Mr Lane, who did not wave back and had appeared to quicken his pace.
He said: "It felt strange, as if I had been ignored."
Later, Mr Lane sent him a friendly text saying "hi, how are you?".
A friend of Miss Grice, Joanne Pumfrey, also gave evidence, saying the victim had felt pressurised by Mr Lane and recounted a occasion when he had puller her hair in a pub.
The prosecution asserts Mr Lane, of Thornhill Rise, Portslade, East Sussex, was "obsessed" with Miss Grice and refused to accept their break-up, or her new relationship with Ashley Cooke.
It is alleged, after months of stalking her, he slit the teenager's throat before setting fire to her bedroom in Chrisdory Road, Portslade, in August.
A neighbour of Miss Grice, Sarah Thompson, told the court earlier that about three weeks before her death she saw and heard arguments at Miss Grice's home.
The trial continues on Monday.


A man is due to appear in court accused of murdering Gordon James Smith in a Lake District town.

Mr Smith, 44, was found dead lying in Lake Road in Windermere early on 1 July.
Cumbria Police said Mark Russell, 26, of Holly Terrace in the town, has been charged with murder and remanded in custody.
He is due to appear at Furness and District Magistrates Court on Monday.
A woman, aged 48, and a 15-year-old girl, both from Kent, have been bailed until 10 July and a 31-year-old man from Millom has been bailed until 17 July.


People who need to see specialists at Jersey hospital for obesity problems face an average of a four-year wait.

The target waiting time for referrals is 13 weeks, but some patients must wait considerably longer.
The health and social services department tries to see patients within three months of being referred by their GP.
For some problems, such as sports injuries, diabetes or general surgery, the average wait is about six months.
Figures released by Jersey's health department show some patients referred to the hospital for bariatric surgery are having to wait over four years for treatment.
Data released by the department has shown that less than a third of specialist areas have a waiting list longer than the target.
But women needing to see a specialist before giving birth are able get an appointment right away after being referred by their GPs.
People with back pain, adult mental illness or needing breast surgery, also have less than a month to wait before they are able to see a specialist.


All slots giving free access to a new viewpoint on a historic building were booked up less than 24 hours after it was first opened to the public.

Inverness Castle Viewpoint allows for 360 degree views of Inverness and surrounding area.
High Life Highland, which runs leisure sites on Highland Council's behalf, said all the free slots were booked by lunchtime on Tuesday.
Entry fees to access to the viewpoint on the North Tower begin on Saturday.
After Easter Monday's opening day, 1,100 slots were available.
High Life Highland said all the slots have been booked.
Highland Council, which owns the tower, said the viewpoint was the first phase in transforming Inverness Castle into a major tourist attraction.
The 175-year-old property is currently the base for the city's courts service, which is to be moved to a new building.


German Chancellor Angela Merkel's main rival in this month's election has accused her of causing misery by imposing austerity on southern Europe.

In their only head-to-head TV debate, centre-left candidate Peer Steinbrueck called her euro policies a failure.
But Mrs Merkel pointed to Germany's healthy economy, calling it "the motor of growth" in Europe.
The event was seen as Mr Steinbrueck's biggest chance to claw back Mrs Merkel's lead in the opinion polls.
The chancellor's conservative coalition is reckoned to be leading Mr Steinbrueck's Social Democrats (SPD) by around 15 points (40% to 25%).
By Stephen EvansBBC News, Berlin
Bread-and-butter economic issues dominated more than an hour of the 90-minute debate.  Chancellor Merkel portrayed herself as someone the voters knew and could trust - a safe pair of hands in difficult times.
On the other hand, SPD candidate Peer Steinbrueck emphasised what he saw as the cost of success to ordinary people -  a low pay sector "like hardly any other country in Europe".
Who won? Instant polls after the event were pretty evenly split, some giving Angela Merkel the edge.
What is certain is that neither person delivered a knock-out punch that radically changed the course of the campaign.  Chancellor Merkel went into the debate with overwhelming approval, and that position is unlikely to have been completely reversed.
However, even with those figures, Mrs Merkel would still need a coalition partner, meaning the outcome of the election remains uncertain.
With three weeks to go before the 22 September vote, the two candidates were grilled by four journalists before an estimated TV audience of up to 20 million.
Mr Steinbrueck, who was Mrs Merkel's finance minister in the 2005-09 "grand coalition" between left and right, attacked her handling of the European debt crisis.
"I would have followed a different crisis strategy. Of course there must be budget consolidation in these countries, but not a deadly dose," he said.
"Germany once got help too and we must not forget that. Germany was massively helped after the Second World War with the Marshall Plan."
"You voted for everything," Mrs Merkel retorted, pointing out that the SPD had supported her policies in parliament.
Mr Steinbrueck said Germany had the biggest low-pay sector in Europe, and that he wanted to ensure greater "social justice," by introducing a national minimum wage and higher taxes for the biggest earners.
The chancellor said Germany had more people in work than ever.
"We must not do anything to put jobs at risk and the tax hike plans of the Social Democrats and the Greens bring with them the risk that we spoil the good situation that we have instead of improving it."
So far, there have been few campaign issues that have exposed major policy differences between the two figures and the parties have focused on their personalities.
Mr Steinbrueck is often witty but prone to gaffes, while Mrs Merkel often seems less than comfortable in the cut and thrust of live debate, the BBC's Berlin correspondent Stephen Evans reports.
A snap poll for Germany's RTL television declared Merkel a narrow winner of the debate, while an ARD TV poll suggested Mr Steinbrueck had been more convincing.
However, Mr Steinbrueck did not appear to land the sort of knock-out blow that would change the course of the campaign, our correspondent says.
The leaders of the smaller parties taking part in the election will have their own election debate on Monday.
Mr Steinbrueck, 66, has said he will not enter a grand coalition with Mrs Merkel's Christian Democrats.
He would prefer to go into coalition with the Green Party, while Mrs Merkel is hoping to continue her governing alliance with the liberal Free Democrats (FDP).
However, the FDP has lost much of its support since the last election, and if it does poorly Mrs Merkel and Mr Steinbrueck may be forced to work together.


Firefighters say they have contained a blaze that broke out at a recycling plant overnight.

Eight appliances were sent to fight the fire at Wardley industrial estate near Swinton, Greater Manchester Fire and Rescue Service said.
The fire is believed to involve a large number of recycled computer parts in an industrial-sized container.
A number of people were evacuated from their homes but there are no reported injuries.
A downed power line also caused problems at the scene and was being made safe by the National Grid, the fire service added.
Firefighters managed to bring the flames "well under control" just after 02:00 BST, with people in the surrounding area advised to keep their windows and doors shut to prevent smoke from seeping into their homes.
Darren Moore, force duty officer for Greater Manchester Police, said: "At 11.23pm police attended a large fire at a recycling plant to assist the fire brigade.
"The fire is believed to be contained although it will continue to be fought overnight."
Eleven people were transferred from their homes into emergency accommodation, he said, with others leaving to stay with family and friends.
The cause of the fire is unknown and an investigation will take place.


Russia' Gazprom has given Ukraine more time to settle its gas bill after receiving a part payment of $786m (Â£469m).

The company had previously threatened to halt shipments of gas unless Ukraine paid its bill in full and agreed in future to pay in advance.
Gazprom says Ukraine still owes it almost $2.5bn.
Negotiations between the two sides will resume now that a part payment has been made.
Ukraine announced on Friday that it had made a payment, but has refused to settle the full amount in protest against Gazprom's recent 80% price increase.
Russia said the money received on Monday covered gas shipped in February and March.
"We welcome Ukraine starting to pay back its debt and postpone the pre-payment regime until 9 June," said Alexei Miller, Gazprom's chief executive.
Analysts said the payment gave Ukraine a little more time to continue negotiating on the price of gas it buys from the gas giant.
"Even though the $786m seems to be less than expected, this could provide some short-term relief with regard to Russian-Ukrainian price negotiations," said VTB Capital.
Gazprom now charges Ukraine $485.50 per 1,000 cubic metres, against the old price of $268. At the new price, Ukraine is paying more for Russian gas than any other European country.
Almost 15% of gas used in Europe comes from Russia via Ukraine, which is why EU members are taking a particularly close interest in the stand-off, observers say.


The family of a teenager who vanished nine years ago has welcomed a police appeal for information about a Volvo car seen on the night he went missing.

Luke Durbin, 19, of Hollesley, Suffolk, failed to return home after a night out in Ipswich on 12 May 2006.
His mother Nicki said when a police team took over the case and interviewed her for six hours she was able to put more emphasis on the car.
She had always believed the owner of the Volvo car was significant.
"I am hopeful someone will now come forward and I am convinced there is someone out there with relevant information," she said.
"Despite the disappearance being nine years ago I am sure someone locally knows something.
"It's a relief to know the team is now looking seriously at the importance of the car."
Police know the silver or white Volvo 440 was seen in Orwell Place in Ipswich at 04:19 BST on Friday 12 May 2006, just minutes after the last CCTV images of Luke .
Officers are keen to trace the driver and any occupants of the vehicle.
Mr Durbin had spent part of the evening in Zest nightclub on Princes Street before leaving in the early hours.
The last sighting of him was on CCTV walking across Dogs Head Street in the direction of the bus station.
Det Supt John Brocklebank said: "Someone locally knows what happened to Luke, however we are still waiting for the crucial piece of information that can solve the mystery.
"We're releasing the CCTV images of a Volvo seen in the area.  Despite appeals we have not been able to trace the occupants of this car.
"We'd like to hear from anyone who knows someone who had access to a silver or white coloured Volvo 440 around May 2006 who may have been in Ipswich around 04:00 BST that day."


Pope Francis has urged Israeli and Palestinian leaders to show courage to seek peace in the Middle East.

The Pope was speaking after hosting joint prayers at the Vatican with Israeli President Shimon Peres and his Palestinian counterpart, Mahmoud Abbas.
Mr Peres said making peace was a "holy mission". Mr Abbas spoke of a "comprehensive and just peace".
The Pope has stressed that the Vatican is not seeking to get involved in peace negotiations between the two sides.
The talks collapsed in acrimony in April.
Pope Francis had invited the pair on his recent trip to the Holy Land.
The three men, and the spiritual head of the Orthodox Christians, Patriarch Bartholomew, were driven together to the Vatican gardens.
The Pope then sat between the two presidents as a chamber orchestra played.
"Peacemaking calls for courage, much more so than warfare," Pope Francis said.
"Instil in our hearts the courage to take concrete steps to achieve peace," he prayed.
The Israeli president said: "It is within our power to bring peace to our children. This is our duty, the holy mission of parents."
"O Lord, bring comprehensive and just peace to our country and region so that our people and the peoples of the Middle East and the whole world would enjoy the fruit of peace, stability and coexistence," Mr Abbas said.
The three men then shook hands and planted an olive tree.
Vatican officials have insisted there is no ulterior political motive behind Pope Francis' invitation and no concrete initiatives are expected.
Pope Francis has said he'll make no attempt to mediate between his Israeli and Palestinian visitors. He says that's a job for diplomats.
The Pope is trying something a little different here - a spiritual approach. He hopes that the prayers in the calm of the Vatican gardens might just improve the atmosphere between the two sides. And that that in turn might perhaps lead to the opening of new possibilities for peace.
For Pope Francis, the power of prayer has the capacity to change everything.
But those most familiar with the harsh realities of the Israeli-Palestinian dispute are likely to look on with some considerable scepticism.
Mr Peres and Mr Abbas know each other well - they signed the Oslo peace accords in 1993.
The Israeli president occupies a largely ceremonial position and has no formal role in peace talks. He is due to leave office at the end of this month.
But officials say that the Israeli government backs his trip to the Vatican and Prime Minister Benjamin Netanyahu has been in "constant contact" with him.
Sunday's prayer event was organised in minute detail and comprised Jewish, Christian and Muslim prayers.
The holding of such a ceremony is likely to add to the Pope's reputation, correspondents say, as someone who is unconstrained by diplomatic and theological niceties when it comes to advancing the causes of diplomacy and peace.
The BBC's David Willey in Rome says the pontiff has often bypassed the formal machinery that normally conducts Vatican foreign policy.


Satellite images show China is making progress on building an airstrip on a reef in disputed territory in the South China Sea, a report says.

The images, published by IHS Jane's Defence Weekly, show construction work on reclaimed land on Fiery Cross Reef in the Spratly Islands.
The landmass could accommodate a runway about 3,000m long, the report said.
China's land reclamation work in the area has raised concern around the Asia-Pacific region.
China claims almost the whole of the South China Sea, resulting in overlapping claims with several other Asian nations including Vietnam and the Philippines.
They accuse China of illegally reclaiming land in contested areas to create artificial islands with facilities that could potentially be for military use.
Images have emerged of work in multiple areas in the disputed Spratly islands. China says its work is legal and needed to safeguard its sovereignty.
The report from IHS Jane's used images provided by Airbus Defence and Space in February and March.
The later image, dated 23 March, showed a paved section of runway on the north-eastern side of Fiery Cross Reef, as well as paving and ground preparation of other sections of the runway.
The 3,000m length, it said, "would be well within the parameters of existing People's Liberation Army Air Force runways on mainland China, which vary in length from about 2,700m to 4,000m at most".
It also showed dredging to the south of the reef, in apparent work to improve the reef's port facilities.
Additional images showed that China could be building a second air strip on Subi Reef, also in the Spratlys and only 25km from an island with a Filipino civilian population, by creating and then linking three artificial islands, the report said.
China's neighbours are concerned that Beijing is working to entrench a military presence in the South China Sea to reinforce - and make permanent - its claims.
The Philippines said last year it believed China was building an airstrip in Johnson South Reef, in the Spratlys - the extent of work there is not clear. And earlier this week, another report citing satellite images said China was expanding an airstrip on Woody Island, much further north in the disputed Paracel Islands which Vietnam claims.
President Barack Obama has said the US fears China is using "sheer size and muscle" to strong-arm smaller nations over the South China Sea.
A US State Department spokesman says the US does "not believe that large-scale land reclamation with the intent to militarise outposts on disputed land features is consistent with the region's desire for peace and stability".
But China insists it is acting within its rights.
"China's work on the [Spratly] islands mostly serves civil purposes apart from meeting the needs of military defence. China is aiming to provide shelter, aid in navigation, weather forecasts and fishery assistance to ships of various countries passing through the sea," a commentary carried prominently by Xinhua news agency on Thursday read.


Tottenham have completed the signing of Burnley right-back Kieran Trippier on a five-year-deal.

The 24-year-old moves to Spurs for an undisclosed fee from the Clarets, who he joined in 2012.
The former Manchester City trainee made 185 appearances for Burnley, and started every Premier League game last season.
"When I first heard that the club was interested I didn't have to think twice," Trippier said.
"It's such a big club and now I just can't wait to get started and show everyone what I can do."
Trippier becomes Mauricio Pochettino's second signing of the summer after Spurs signed Cologne defender Kevin Wimmer for an undisclosed fee on a five-year deal.
Trippier added: "I'll take every opportunity I get with both hands and hopefully play my part for everyone at the club.
"Whenever I get a chance, I want to do well for the other players, the staff and, of course, the fans."
Trippier did not make a first-team appearance for Manchester City, and had a loan spell at Barnsley before moving to Turf Moor, initially on loan.


GCSE pupils in Northern Ireland have shown improvements in English, Maths and Science.

Those gaining A* to C grades in English rose from 68.8% to 73%, Maths rose 1.6% to 66.2% and Science from 61.5% to 64.8%.
Overall, the number of pupils achieving A* to C grades increased by 1.5% to 78%.
While more boys achieved A* to C grades than last year, girls continued to outperform them by 7.6%.

Northern Ireland boards test pupils in sections or modules.
Old-style O levels and, from 1986, GCSEs were offered as linear exams, with a single test at the end of two years study.
In 2009, modular style exams were introduced in GCSEs across the curriculum.
They split the course of study into sections or "modules" and each one is tested throughout the two years.
A previous education secretary for England, Michael Gove, decided to change that.
He used two arguments: he wanted to reduce the amount of testing pupils had to cope with and he also thought the linear exam would be more "robust".
Not everyone agrees and some argue that pupils can actually get better results from linear testing.
In Northern Ireland, Education Minister John O'Dowd decided not to follow suit and the exams offered by the CCEA, the Council for the Curriculum, Examinations and Assessment, have retained the option of modular exams.
Performance by students in Northern Ireland in individual sciences was particularly high, the Joint Council for Qualifications said.
The proportion of entries awarded A* to C in Biology sits at 93.3% (91.2% in 2013), in Chemistry 93.6% (93.4% in 2013) and in Physics 95.0% (94.7% % in 2013).
The overall improvement comes despite concerns about changes to the style of test taken by English examination boards.
In English Language, Northern Ireland improved while in Great Britain the results have worsened. The English-based boards dropped the 'speaking and listening' element of the exam, but it was retained by Northern Ireland.
The Joint Council for Qualifications said there were notable performances in Music and modern languages:
CCEA director of qualifications Anne Marie Duffy said the results reflected the hard work of students and teachers.
"The performance in core subjects of English and Mathematics will provide strong foundations for learners as they move on to further education, training and employment," she said.
"This year there has been a 2.8% points fall in the Northern Ireland Year 12 school population, and we've seen GCSE entries decrease by 3,609.
"Against this backdrop, entries in Business Studies and ICT have risen while sciences and modern languages have maintained their popularity."

Manchester City Under-21s won on penalties in their first EFL Trophy appearance, while fellow debutants Tottenham lost in a shootout at Luton.

City were held to a 1-1 draw at League One Rotherham, before securing a bonus point with a 4-2 win on penalties.
Spurs' under-21s earned a point in a 2-2 draw with the Hatters, who beat the visitors 4-2 in the shootout.
League One side Plymouth also won on penalties, beating Chelsea's development squad 5-4 after a 2-2 draw.
There were wins for two Premier League development squads inside 90 minutes, as West Ham and Swansea both earned three points in the opening round of fixtures.
Swindon twice equalised against the Hammers after falling behind, but Dan Kemp slid in a third goal late on to secure the visitors victory at the County Ground.
Kyle Storer gave League Two side Cheltenham the lead early in the second half against the Swans, but Kenji Gorre equalised in the 73rd minute, before Aaron Lewis slotted in an 83rd-minute winner.
Notts County were the only English Football League side to earn the maximum three points, as goals from Jonathan Forte and Haydn Hollis earned the Magpies a 2-1 win over Everton Under-21s.
Swindon Town 2-3 West Ham United Under-21s
Plymouth Argyle 2-2 Chelsea Under-21s (Plymouth won 5-4 on penalties)

Rotherham United 1-1 Manchester City Under-21s (Manchester City Under-21s won 4-2 on penalties)
Notts County 2-1 Everton Under-21s


Germany's vice-chancellor has warned the future of the EU could be in doubt if the UK's exit is handled badly.

Sigmar Gabriel said the EU would go "down the drain" if other states followed Britain's lead and that the UK could not keep the "nice things" about Europe while taking no responsibility.
It comes as Theresa May summoned ministers for a meeting on Wednesday to discuss ideas for the UK's withdrawal.
Downing Street said Brexit was "top" of the prime minister's agenda.
But a report in The Sunday Times suggested her cabinet was split over leaving the single market.
The UK voted to leave the European Union in a referendum vote on 23 June.
Mr Gabriel, who is also economy minister in Germany's governing coalition and Chancellor Angela Merkel's deputy, told a news conference that as a result, the world now regarded Europe as an unstable continent.
"Brexit is bad but it won't hurt us as much economically as some fear - it's more of a psychological problem and it's a huge problem politically," he said.
"If we organise Brexit in the wrong way, then we'll be in deep trouble, so now we need to make sure that we don't allow Britain to keep the nice things, so to speak, related to Europe while taking no responsibility."
Mrs Merkel has met a number of European leaders during the past week to prepare the ground for a September summit focused on the EU's future post-Brexit.
She has said remaining member states must listen to each other carefully and avoid rushing into policy decisions.
Meanwhile, Mrs May is due to begin drawing up blueprints for Brexit on Wednesday, when she hosts cabinet ministers at Chequers, the prime minister's country retreat in Buckinghamshire.
BBC political correspondent Chris Mason said Mrs May would hear different answers to the question "what does Brexit actually mean?" from around the cabinet table and in Parliament.
It comes as a new cross-party group called Open Britain was launched.
In a joint article for the group in the Sunday Times, three former ministers from the Conservatives, Labour and the Liberal Democrats accept that the free movement of people cannot continue, but they warn against "pulling up the drawbridge."
Mr Gabriel also said on Sunday that trade talks between the EU and the US had "de facto failed".
The plan - known as the Transatlantic Trade and Investment Partnership or TTIP - aimed to remove or reduce a wide range of barriers to EU-US trade and investment.
However, the move has been controversial in many of countries involved, including Germany and the UK. Critics say TTIP is driven by big business and would be bad for jobs, consumers and the environment.
In 14 rounds of talks, the two sides had not agreed on a single common chapter out of 27 being discussed, Mr Gabriel said.
"In my opinion the negotiations with the United States have de facto failed, even though nobody is really admitting it," said Mr Gabriel.
He suggested Washington was angry about a deal the EU struck with Canada, because it contained elements the US does not want to see in the TTIP.
"We mustn't submit to the American proposals," said Mr Gabriel, who is head of Germany's centre-left Social Democratic Party, which is in coalition with Mrs Merkel's centre-right Christian Democratic Union.
The BBC's Andrew Walker said ending the negotiations would not be a decision for Mr Gabriel, as he is the leader of centre-left Social Democratic Party, which is in coalition with Mrs Merkel's centre-right Christian Democratic Union.
Nonetheless, Mr Gabriel is an important voice and his view that TTIP has in effect failed is a sign of just how much political difficulty it faces, our correspondent added.
He has also been forced to defend his actions after he flicked the middle finger to a group of right-wing protesters earlier this month.
Sigmar Gabriel said his only mistake was not using both hands, and told his critics to think about what they would do if faced with 12 "young, aggressive, swearing and ready-for-violence Nazis".
Mr Gabriel had been confronted by the hecklers in northern Germany.


Benik Afobe is hurt by claims from Wolves that he was not trying during his final five months at the club before his £9m move to Bournemouth.

Speaking to fans on Wednesday, Wolves head of football development and recruitment Kevin Thelwell said: "Benik was no longer trying to play for us.
"That was undermining everything we were trying to achieve."
But striker Afobe, 22, responded on Twitter: "I wasn't going to comment but this is too shocking and very hurtful."
Afobe, who was the subject of bids from Norwich in August, scored 10 times in 27 appearances for Wolves in 2015-16 prior to joining the Cherries in January.
That strike rate was down slightly on the 13 goals he netted in 21 Championship appearances following his move from Arsenal in January 2015.
"I did my best," added Afobe, who turns 23 on Friday. "It was hard for us all. I asked to leave but only because I wanted to play in the Premier League, but I never told my team-mates or disrupted the changing room."
Wolves chief executive Jez Moxey told BBC WM: "He insisted on moving. We were forced into doing a deal that we didn't want to do.
"We had said publicly that Benik would not be sold this season. It was a statement of intent and the owner [Steve Morgan] backed us completely."
Afobe has since scored three times in five starts since joining the Cherries, but failed to find the net when he appeared against his first club Arsenal on Saturday.
Wolves head coach Kenny Jackett played a straight bat at Wolves' pre-match press conference on Thursday, ahead of Saturday's home game with Preston.
"Benik had a whirlwind year with us," he told BBC WM. "People saw the games. People can make up their own minds."
Jez Moxey and Kevin Thelwell spoke to BBC WM prior to the club's latest Fans' Parliament at Molineux.


About three million EU citizens living in the UK would be allowed to stay after Brexit, Theresa May has proposed.

A new "UK settled status" would grant EU migrants who had lived in the UK for five years rights to stay and access health, education and other benefits.
Proposals were unveiled at a Brussels summit but are dependent on EU states guaranteeing Britons the same rights.
German Chancellor Angela Merkel called the plan a "good start", but Labour said it was "too little, too late".
Many EU citizens in the UK, and Britons living abroad, are worried about their status once Brexit happens. The UK's exit deadline is 30 March 2019.
Addressing other EU leaders at her first summit since the general election, the prime minister said she did not want anyone to have to leave or families to split up.
"No one will face a cliff edge," she said.
"The UK's position represents a fair and serious offer, one aimed at giving as much certainty as possible to citizens who have settled in the UK, building careers and lives and contributing so much to our society.''
Mrs May said the UK wanted to protect the rights of EU citizens in the UK - and the rights of UK expats in other European countries.
But Downing Street has not yet specified what the cut-off date will be for new residents, after which the guarantee would no longer apply. It will be no earlier than March 2017, when the UK formally began leaving the EU by issuing the Article 50 notification, and no later than March 2019 when it will actually leave.
Those arriving up until the point of departure would have a "grace period" - expected to be two years - to build up the same "UK settled status", she told EU leaders.
Mrs May also said the system would be streamlined, doing away with an 85-page permanent residency application form which has attracted complaints.
BBC political editor Laura Kuenssberg said the PM was already on a collision course with her European counterparts over her plan for the rules of the new system to be applied by a British court - Brussels has insisted it must be the European Court of Justice that oversees it.
But she added that the offer was intended to be a symbol that the UK was getting on with Brexit at a time of turmoil at home, in the wake of the general election result which led to Mrs May losing her Commons majority.
Our correspondent said the full details would not be unveiled until next Monday, and it was not yet clear if the offer was as generous as that put forward by the EU a month ago. Details on issues such as the rights of EU citizens' relatives abroad and their descendants, were not yet known.
Labour's Keir Starmer, the shadow Brexit secretary, said: "Labour has been clear that people should not be bargaining chips in the Brexit negotiations.
"The prime minister's offer is too little too late and falls far short of the full and unilateral guarantee Labour would make."
Giving a "clear commitment" that there would be no change in the status of EU nationals in the UK would help deliver the same deal for UK nationals living in the EU, he added.
Liberal Democrat leader Tim Farron said the plans left too many unanswered questions.
"Theresa May could have given a guarantee from day one, instead she has allowed our friends, colleagues and neighbours to live in uncertainty for a year," he said.
"Even now, Theresa May continues to insist on using EU nationals in Britain as bargaining chips and has failed to provide a full and clear right to stay for all."
German Chancellor Angela Merkel told reporters she wanted "the widest possible security guarantees for EU citizens" from the Brexit deal and called the offer "a good start".
She added: "But there are still many many other questions linked to the exit, including on finances and the relationship with Ireland. So we have a lot to do until [the next EU summit in] October."
Both the UK and the rest of the EU say they want to come to an arrangement to secure the status of the 3.2 million EU citizens in the UK and the estimated 1.2 million Britons living in EU countries.
The European Union has said they should continue enjoying the same rights, enforceable by the European Court of Justice.
UK opposition parties had urged the government to make a unilateral guarantee to the EU migrants - but ministers have insisted a reciprocal deal is needed to ensure British expats are protected.
The gathering of 28 EU member states' leaders came the day after measures to enable Brexit dominated the Queen's Speech. Mrs May's Conservatives are still trying to secure the Commons support needed to pass their programme.
Mrs May was not present when the leaders of the remaining 27 EU states held a brief discussion about Brexit after her presentation.


More than 500m cheques were written in 2015, confounding expectations that the payment method is disappearing.

However, Payments UK, which represents the industry, said that still represented a 13% decline on the previous year.
It said the figures showed that cheques are still valued as a means of payment.
Cheques had been due to be phased out by 2018, until MPs forced a change of heart by the industry.
Banks have promised to keep processing them for as long as necessary.
Some banks, such as Barclays, have also introduced  "cheque imaging", allowing consumers to take a photograph of a cheque and send it to the bank via their smartphone.
Use of cheques peaked in 1990, when there were more than 4bn transactions a year.
Last year 546m cheques were written, an average of about 10 cheques per adult per year.
The report for Payments UK said that showed that they are "still valued as a convenient and secure method of payment by those who choose to use them".
Use of cheques is higher in the 65 and over age group. They are also still popular as a way of paying tradespeople and charities, as well as for family gifts.
The research also suggested that the use of debit cards would overtake cash payments by 2021.
However, cash was still the most popular means of paying in 2015.
Figures published last week showed that monthly spending on contactless cards hit Â£1.5bn for the first time in March.
Consumers over the age of 60 are the fastest-growing group using the cards, according to Barclaycard.


Armagh saw off Fermanagh 0-16 to 0-11 to win the Football League Division Three final at Croke Park.

Fermanagh made the better start but Armagh led 0-8 to 0-6 at half-time despite having Finian Moriarty sent-off in the 26th minute.
Four unanswered points saw the Orchard County extend their lead, before the Ernemen battled back to trail by three.
Stephen Harold (2) and Kevin Dyas scored late points to extend Armagh's winning margin to five.
Jamie Clarke was named man of the match.
Pete McGrath's side were quickly out of the blocks as Tomas Corrigan's superb initial point from play was quickly added to by two Sean Quigley frees.
The margin remained three at the 13-minute mark after a Tony Kernan free was quickly cancelled out by a Ruairi Corrigan effort from play.
However, Armagh regrouped to level by the 22nd minute helped by a couple of poor kick-outs from Fermanagh custodian Thomas Treacy.
The levelling score should have been a goal as Aidan Forker blazed over after a superb defence-splitting pass from Miceal McKenna.
Armagh looked to have suffered a major blow in the 26th minute as centre half-back Moriarty received his marching orders after receiving a yellow card, black card and red card in the same incident as he hauled down the speedy Ruairi Corrigan.
But despite being a man down, Armagh bossed the remainder of the first half as three Tony Kernan frees helped them move into a 0-8 to 0-6 lead by the break.
Armagh's interval lead could have been even bigger with Erne keeper Treacy making a great full-length diving save to turn a point-blank Dyas shot out for a 45.
Ciaran McKeever entered the fray for Armagh in the second half and points from Kernan and Ethan Rafferty (2) saw them assume control.
Armagh had a goal disallowed as the ball was illegally taken out of the Fermanagh goalkeeper's hands, while for Fermanagh, Quigley was instrumental in reviving his side's hopes with a series of points, before Armagh rallied.
Armagh: N Geoghegan; A Mallon, C Vernon, M Murray; J Morgan, F Moriarty, M Shields; C McKeever, A Findon; T Kernan, M McKenna, A Forker; E Rafferty, A Murnin, J Clarke.
Fermanagh: T Treacy; M Jones, T Daly, M O'Brien; B Mulrone, R McCluskey, N Cassidy; R Jones, R O'Callaghan, P McCusker, R Corrigan, D McCusker; T Corrigan, S Quigley, C Flaherty.


Severely deaf people who use cochlear implants will receive the latest hearing aid upgrades every five years, the Scottish government has announced.

Ministers said the Â£3.2m plan would make sure patients benefited from the most up-to-date technological advances.
A cochlear implant is surgically-implanted behind the ear.
It works with a sound processor to allow people with severe deafness to regain some hearing.
The effect can be dramatic - helping profoundly deaf children to go to mainstream schools and older people to be less isolated.
Newer processors are being developed all the time which improve sound quality.
Until now, they were only replaced if they stopped working.
Health Secretary Shona Robison said the government investment would "improve patients' quality of life".
She said: "This is a substantial investment in a small, specialised service which will make a real difference to those children and adults who rely on cochlear implants for a better quality of life.
"For children, especially young children, cochlear implants can give an understanding of sound that will help them develop speech and language skills that allow them to integrate into mainstream society.
"The technology in this area is developing all the time, with newer, better processors becoming available that can improve sound quality and the functionality of the device.
"It is only right that we give patients access to this life-changing technology and I'm extremely pleased to be able to announce the funding that will deliver a roll-out of this national five-year upgrade programme."
About one in every 1,000 children is severely or profoundly deaf by the age of three and this rises to two in 1,000 by the age of 16.
The use of cochlear implants is also increasing among older people who develop deafness as part of the ageing process.
Heather Gray, director of the National Deaf Children's Society Scotland, welcomed news of the technology roll-out.
She said: "With the right support, we know that deaf children can achieve as much as their hearing peers.
"But the persisting education attainment gap for deaf children shows we still have much to do to ensure we are getting it right for this small, often overlooked group of children.
"This investment is a step towards closing the gap and is very welcome."


Britain's Laura Muir just missed out on a 1500m medal as Kenya's Faith Kipyegon won a showdown every bit as tight and dramatic as billed.

Media playback is not supported on this device
In the contest of the championships so far, Muir led through the first lap before slipping back as the pace dropped.
With 30m to go, the 24-year-old Scot had battled back into contention only to be overtaken by American Jenny Simpson and South Africa's Caster Semenya in the final strides.
"I gave it everything I could," said Muir, who missed out on bronze by seven hundredths of a second.
"I tied up in the last 15 yards. I knew it was close. It happened so late in the race. I couldn't react, but I wouldn't have been able to because I was so tired."

With Ethiopian defending champion Genzebe Dibaba nowhere and the Netherlands' Sifan Hassan, fastest woman in the world this year, tying up at the death, it was a frenzied end to a race as messy as it was thrilling.
Muir's fellow Briton, Laura Weightman, crossed the line in sixth place.
Minutes earlier, Olympic champion Omar McLeod had given Jamaica its first gold medal of these championships as he powered to 110m hurdles gold.
But it was the 1500m that had the capacity crowd on its feet, and while Muir's effort was brave, there will be debate about whether her tactics were the right ones for the occasion.
After a first lap of 65 seconds she slowed it down to 71secs on the next, with Hassan and Simpson coming past her as she ceded control.
At that stage Olympic 800m champion Semenya was way back, but the South African used her speed in the home straight as USA's Simpson once again timed her own effort to perfection as Dibaba went backwards.
McLeod, 23, a sub-10 second runner over 100m flat, had held off Sergey Shubenkov by a tenth of a second in 13.04secs, with Hungary's Balazs Baji in bronze.
Shubenkov is competing here as a neutral athlete, one of 18 Russians cleared by the International Association of Athletics Federations' doping review board following the World Anti-Doping Agency report into their nation's state-sponsored doping programme.
But there was no fairytale return to this stadium for American 2012 Olympic champion Aries Merritt, who had a kidney transplant operation two years ago.

Yulimar Rojas won Venezuela's first ever World Championship gold as she held off reigning champion Caterine Ibarguen in a see-saw triple jump final.
Rojas' 14.91m in the penultimate round stole back a lead that Ibarguen had herself taken back with her third-round 14.89m, the Colombian going close again in the final round only to come up three centimetres short of gold.
There were hopes within the British team that Sophie Hitchon might replicate or even improve upon the hammer bronze she won at the Olympics a year ago.
But with Poland's double Olympic champion Anita Wlodarczyk, responsible for the 13 biggest throws of all time, taking the most predictable gold of the championships with her fifth-round 77.90m, Hitchon's final round throw of 72.32m was her biggest of the night but enough only for seventh.
The 26-year-old from Blackburn struggled to hold back the tears afterwards, her personal disappointment also bad news for a team that have already seen medal hopes Katarina Johnson-Thompson, Holly Bleasdale and Andy Pozzi miss out.
"I felt like I was in better shape and if I had the rhythm I had in qualification, you don't know what could have happened," said Hitchon.
"Of course I am [going to beat myself up about the result], that's part of my personality."

World and Olympic 400m champion Wayde van Niekerk set up his bid for double gold as he won his 200m heat, Danny Talbot running a new personal best with an identical time of 20.16secs in second.
"I think I'm in the best shape of my life, so I'm just trying to go with it," said Talbot. "I'm very grateful to be in the position I am."
Van Niekerk goes for 400m gold on Tuesday night, but the South African's great rival Isaac Makwala, the fastest man in the world this year, now has only the one-lap event in his sights after being struck down by food poisoning before his own 200m heat.
Britain's Nethaneel Mitchell-Blake went through as an automatic qualifier after winning the seventh heat in 20.08secs, his compatriot Zharnel Hughes joining him as fastest loser.
British team captain Eilidh Doyle and Meghan Beesley both moved into the 400m hurdles semi-finals, but Jack Green is out after coming home fourth in his semi-final in 49.93 secs.
Paula Radcliffe, marathon world record holder: "Regarding Muir's tactics, it's so hard when you're in that situation and racing - you're the only one who can make those decisions. It nearly paid off."
Brendan Foster, Olympic 10,000m bronze medallist: "A race plan with a second lap of 71 seconds isn't a brilliant race plan in my view. It can play into the strength of the sprinters. Muir's running in the last 400m was strong, she went a bit fast on the final bend which took a bit out of her. She was unlucky."
Darren Campbell, Olympic 200m silver medallist: "The reality is that Mo Farah has the only medal. He is retiring from the track. What are we pinning our hopes on? Some guys have made finals. That is good for next time. But we have got something wrong. If medals are not won, the funding is cut. All this stuff the young athletes have been given will go."


Chelsea took another step towards clinching the Premier League title after a goalless draw at Arsenal ensured they remain 10 points clear at the top of the league.

Jose Mourhino's side will clinch the title if they follow victory at revitalised Leicester City on Wednesday with three points against Crystal Palace at Stamford Bridge next Sunday.
Arsenal's fans vented their frustration with chants of "boring boring Chelsea" at the final whistle after the Gunners failed to make the most of their second-half chances, but this was the performance of a side fixing a steely gaze and determination on the title.

The criticism fell on deaf ears as Chelsea's players celebrated earning a vital draw - especially captain John Terry as he gave triumphant clenched fist salutes before taking the acclaim of the visiting supporters.
Arsenal manager Arsene Wenger will have been as frustrated as his team's fans, having now gone 13 games without a win against his old adversary Mourinho. The Gunners had plenty of possession but could not find the inspiration to alter that grim statistic.
Chelsea mounted a defensive rearguard action after the break with Per Mertesacker and substitute Danny Welbeck missing from the rare opportunities that fell Arsenal's way.
It was not all one way, however, and Chelsea complained bitterly about three first-half penalty claims that were ignored by referee Michael Oliver, twice for incidents involving Oscar and the other on returning former Arsenal star Cesc Fabregas.
Ultimately, though, Mourinho and Chelsea will regard this as another precious point on what now seems the formality of the first title triumph of his second spell in charge at the club.

Mourinho's decision to operate without a recognised striker after injuries to Diego Costa and Loic Remy did not prevent Chelsea getting players into the Arsenal area - and he was left bemused as those penalty appeals went unanswered.
Referee Oliver did not penalise Hector Bellerin when Oscar fell under his challenge and the same player was involved again when he was cleaned out by Arsenal keeper David Ospina as they challenged for Fabregas's pass.
Oscar was left prone and required lengthy treatment amid much animation from the Chelsea bench, who were left nursing a sense of injustice once more.
The third claim came when Fabregas fell theatrically to the floor after coming into contact with Santi Cazorla. The only outcome, much to the delight of Arsenal's fans, was their former idol being shown a yellow card for diving.
Amid this chaos, chances were at a premium but Ospina came to Arsenal's rescue with a fine low save from Ramires after he ran on to Willian's pass.
Chelsea keeper Thibaut Courtois remained untroubled apart from one routine save from Mesut Ozil.
Mourinho made a change at half-time, sending on Didier Drogba for Oscar, who may well have been feeling the after-effects of that collision with Ospina.
Arsenal had a rare opening when Courtois could only half-clear a free-kick but the loose ball did not fall to the ideal person, giant defender Mertesacker screwing a finish well wide.
Welbeck then scuffed a clear chance in front of goal in stoppage time as Arsenal did most of the second half pressing - and Chelsea held out to leave their supporters celebrating a vital point.
Arsenal manager Arsene Wenger:
"In the first half we had the right intensity. We dropped that in the second half and came back into the right level for the last 20 minutes.
"We could have finished the game off. Mesut Ozil had a great chance in the final minute of the game.
"But they came to defend well, and they did that well, and everybody knows that."
