A teacher at a French preschool who said he had been stabbed by a man shouting "Islamic State" has admitted he made the story up, prosecutors say.

The teacher said he had been attacked while alone in a classroom in Aubervilliers, a suburb of Paris.
But prosecutors said he had wounded himself with a box cutter and was now being questioned as to why he lied.
France remains on high alert following the terror attacks in Paris on 13 November that left 130 people dead.
The 45-year-old teacher - who has not been named - has been treated in hospital for superficial wounds to his side and neck.
According to his account, a man had attacked him with a box cutter at about 07:10 (06:10 GMT) on Monday and had shouted: "This is for Daesh [Islamic State]. It's a warning".
The incident sparked a manhunt in the northern suburb, as police tried to track down the alleged attacker.
The anti-terrorism branch of the Paris prosecutor's office also opened an investigation for attempted murder in relation to a terrorist act.
Earlier on Monday, Education Minister Najat Vallaud-Belkacem visited the scene and vowed to increase security at French schools.
All classes at the Jean-Perrin preschool were cancelled.
Mayor of Aubervilliers Pascal Beaudet said it was not yet known what had motivated the teacher to lie.
He said the teacher had 20 years' experience and was "appreciated" by parents at the school.
Last month, the Islamic State's French-language magazine Dar-al-Islam recently urged followers to kill teachers in France, describing them as "enemies of Allah" for teaching secularism.
Rachel Schneider, of the French primary school teachers' union SNUipp, said many teachers had been alarmed by the threat.
"We have received many calls from colleagues, who are very worried," she said.
"They don't necessarily think there will be an organised attack, but they fear this message of murderous madness will inspire unstable people to action."
Aubervilliers is in the Seine-Saint-Denis department of the Ile-de-France region.


At least 30 people have been killed and another 10 wounded in fighting between rival sectarian militias in the Central African Republic (CAR), police say.

Officials say most of those who died in the central town of Dekoa were civilians hit by stray bullets.
The predominantly Christian anti-Balaka militia attacked positions held by mainly Muslim Seleka rebels, they say.
CAR exploded into violence in early December amid mounting resentment toward a Muslim-led government.
Muslim rebels seized power in March 2013 by overthrowing President Francois Bozize - who had been in power for a decade.
CAR's peacemakers
The rebel leader who replaced him, President Michel Djotodia, was accused of failing to prevent his forces from raping, torturing and killing civilians - particularly among the country's Christian majority.
When Mr Djotodia's government fell in January, Christian militia fighters began attacking Muslim civilians in retaliation.
Thousands have been killed since the conflict began and tens of thousands more have fled the country. The UN says that about 1.3 million people - a quarter of the population - are in need of aid.
The UN Security Council is due to vote on Thursday on expanding the nearly 5,000-strong African mission in CAR into a UN peacekeeping operation.
UN Secretary General Ban Ki-moon has warned of "ethno-religious cleansing" in CAR, with lynchings, decapitations and sexual violence all going unpunished.
Some 6,000 African and 2,000 French peacekeepers are currently struggling to keep the violence in check.
Correspondents say that they face a hugely difficult task as Seleka rebels, who have been pushed north from the capital, Bangui, attempt to regroup.
French military police have, however, begun patrolling the streets of Bangui as the first part of a new European Union combat force which is expected to number 800 troops by the end of May.
In the latest violence, police said that the anti-Balaka militia attacked Seleka positions early on Tuesday morning in Dekoa, about 300km (180 miles) north of Bangui.
They said that the fighting escalated when the Seleka called in reinforcements and went on for more than four hours.
"Most of the victims were civilians who were hit by stray bullets," a police source told the AFP news agency.
Meanwhile the US ambassador to the UN on Wednesday urged more support for African and French troops in CAR ahead the UN peacekeeping vote.
Ambassador Samantha Power - currently in CAR - said that the African peacekeeping mission was working hard to fill the gap left by the departure of about 850 troops from neighbouring Chad and were being deployed into the areas they previously guarded.
CAR is rich in gold, diamonds and other natural resources but decades of unrest and mismanagement have left most of its people stuck in poverty.


A Californian software firm is creating 89 jobs in Belfast with the development of a UK sales and operations centre.

Revel Systems makes technology that allows iPads to be turned into cash registers as well as allowing retailers to analyse sales, organise rotas and manage payrolls.
The product is mainly used by small and medium retailers and food businesses.
The Belfast investment is being supported with grants of almost Â£700,000.
Revel employs about 200 people worldwide but expects to grow to around 1,000 over the next 18 months.
The firm was founded in San Francisco in 2010 and recently raised $100m (Â£64m) in a third round of investment.
Lisa Falzone, the co-founder and chief executive, said the firm was "excited" about market opportunities in the UK and Europe.
She said: "We are excited to help European merchants take their businesses to the next level and are looking for dynamic leaders with real entrepreneurial spirit who can continually look for new creative solutions to meet customers' needs."
Point-of-sale technology, using tablet computers and cloud-based storage, is a growth industry.
Another US-based point-of-sale firm, Shopkeep, already has an operation in Belfast that employs about 35 people.


Graeme Shinnie admits he keeps replaying Thursday's wonder strike that secured a 2-1 Europa League first-leg win over Apollon Limassol.

The Aberdeen midfielder was at Hampden Park as the Scottish Premiership's 12 club captains looked forward to the start of the domestic season.
"I am still watching it now in the car down," Shinnie said of his 25-yard drive against the Cypriots.
"It was one that I enjoyed and one that's taken a long time to come."
Shinnie scored three goals last season - and has hit the net four times since joining the Dons from Inverness Caledonian Thistle two years ago.
"I've probably never scored a goal like that in my career, so to do it on that stage in a packed-out Pittodrie was something I enjoyed," said the 25-year-old.
Aberdeen are looking to avoid a fourth exit in a row in the third qualifying stage of the Europa League, but Shinnie thinks they have their best chance yet to reach the play-off stage.
"It would be massive," he said. "Since I have been here, we have always nearly been into this round and it has been frustrating in some of the games we went out.
"Even Maribor last year, I thought we were the better team over the two legs.
"But we are in a different situation this time, going over with a lead."
Shinnie thinks the Aberdeen squad has better strength in depth following manager Derek McInnes' summer recruitment and that gives him added confidence that they can protect their lead on Thursday.
"They were good opposition," he added. "Especially at home in Cyprus with the heat and the home atmosphere and everything else, it will be a tough game, but we know we can do it.
"It is going to be a different experience from the last round - we went over there knowing we had to score and had to win.
"But this one we are in front, so we don't need to score, although I think we can score.
"I think they showed that we can exploit their weaknesses and there will be chances over there.
"But they will be the team that will be coming out trying to attack and needing a goal."


Parents of children being treated at a new £28m women and children's centre say sewage leaked on to a ward.

The centre in Telford opened to patients in September.
Parent Alison Davies-Friend said the sewage came down the walls of the children's ward two weeks ago.
Shrewsbury and Telford Hospital NHS Trust said there had been issues with leaking pipes in the women's services ward, above the children's ward.
Debbie Kadum, chief operating officer, said: "This has not impacted on patient safety.
"However, we recognise that at times, some people have noticed a smell as a result of leaks.
"We are aware of the issues and we and our contractors Balfour Beatty are working hard to resolve them."
The centre, which relocated from Shrewsbury, is the main base for children requiring an overnight stay, ongoing cancer treatment and haematology care.
But other parents have also said there have been treatment delays since it opened and say it does not cater for families, there are no toys for the children or wi-fi-connection.
Heather Noden, from Market Drayton in Shropshire, said her nine-year-old daughter, Molly, had to wait two days for a blood test compared to waiting just 15 minutes at the previous centre in Shrewsbury.
Lynne Evans, from Llangadfan, said: "There's nothing for them to do toy-wise, craft-wise, computer-wise, nothing that my daughter relied on to give her some of her life back.
"I came away very upset for children who are fighting for their lives now."
The trust said it takes time to learn how best to provide a service in a new environment, but it was already seeing big improvements in response times for blood tests and it was confident these would continue. to improve.
The spokesman said the first priority had been to ensure the safe transfer of clinical services.
"Now that we have moved into the new unit we all have an opportunity to understand what it feels like to work there and to receive care.
"This gives us an opportunity over the next few weeks to work with patients and families to design a great environment of care.
"This includes choosing the images for the walls, agreeing on the right toys and equipment and installing wi-fi for patients and their families."


Government-backed forces in Libya have made their largest gains yet into so-called Islamic State (IS) territory in Sirte city since their offensive began in May, officials say.

Troops advanced more than 1km (0.6 miles) into areas previously held by IS, re-taking residential districts.
Dozens of soldiers and IS fighters were reportedly killed.
Sirte is IS's most significant stronghold in Libya. It has been under IS control since February 2015.

Libyan government forces announced on their official Facebook page that they also had control of an official radio station and power management facility.
Al-Jazeera reports that the troops have also recaptured an IS ammunition store.
Troops loyal to the unity government, which was formed in the capital Tripoli earlier this year, had already re-captured the port and other parts of Sirte.
Meanwhile, a mystery explosion in a town close to Tripoli has killed at least 25 people, apparently after a dispute at a shop escalated.
The blast took place in Garabulli after clashes between locals and militia fighters from the city of Misrata.
Officials initially said a munitions store had exploded but one resident told the BBC a lorry loaded with fireworks had exploded.


A pet shop owner who is hand-rearing a young magpie said he has had offers of £1,000 to buy the bird "but wouldn't sell him for 10 times that much".

Peter Redwood-Smith, 21, from Rayleigh, Essex, took Pica on after a customer found him injured outside the shop.
Mr Redwood-Smith said the magpie stuck by him constantly although the bird was free to fly away at any time.
"I'm very connected to him, he's kind of like a child - not to sound too soppy - he's bonded up to me," he said.
As reported by The Essex Chronicle, Pica was rescued from the clutches of a cat when he was about two weeks old.
"One of my customers found him just outside my shop and saved him from being dinner, because he was so wobbly he couldn't outrun the cat," Mr Redwood-Smith recalled.
I knew a bit about magpies before this - I knew the Latin was pica pica, and that's where I got his name.
"I knew the diet, and I knew they were intelligent but I didn't know to the full extent, and after researching I found they're more intelligent than I could have imagined."
Pica is fed on a diet of cooked chicken, duck and turkey, as well as raw pheasant and meal worms, crickets and locusts, which they eat in the wild.
Mr Redwood-Smith said his feathered friend had "flown off on several occasions" in the seven weeks they have been living together, but had always come back.
He said the birds, which have a lifespan of 20 years, "bond up to their mate for life".
"I'm ready for 20 years of magpie friendship, whether I want it or not - I think I'm stuck with him and he's stuck with me."
The RSPB says it does not recommend hand-rearing young magpies as they can seek human company when released back into the wild.


Chad has banned people from wearing the full-face veil, following two suicide bomb attacks on Monday.

Chad's government accused Nigerian militant Islamist group Boko Haram of the bombings which killed more than 20 people.
The prime minister said the veil was used as a "camouflage" by militants and said the security forces will burn all full-face veils sold in markets.
Chad is to host a new regional force set up to tackle Boko Haram.
The militant group has not commented on the attack but has previously threatened to attack Chad, after its forces started to help Nigeria.
At a meeting with religious leaders, Prime Minister Kalzeube Pahimi Deubet said the ban applied everywhere, not only public places.
He added that any clothing that covers everything but the eyes was a camouflage.
The attackers were on motorcycles when they blew themselves up outside two police buildings in the capital, N'Djamena.
Borno state, at the heart of the insurgency, is on the Nigerian border with Chad and Chadian forces have played a key role in helping Nigeria battle the jihadist group.
The US announced on Tuesday that it will give $5m (Â£3.2m) towards a multi-national task force headquarters in Chad.
The BBC World Service's Africa editor Richard Hamilton says Boko Haram militants have increasingly been using female suicide bombers in Nigeria, as they are more likely to smuggle bombs into public places without detection.
The majority of the population in Chad is Muslim and the burka is worn mainly for religious reasons, but  also helps protect women from the hot, dusty climate of the Sahara.
The full-face Islamic veil was also banned in May in public places in Congo-Brazzaville, to "counter terrorism".
Although there has never been an Islamist attack in the country and less than 5% of the population of Congo-Brazzaville is Muslim, thousands of mostly Muslim people had fled the neighbouring Central African Republic and had taken shelter in mosques.
Africa as it happened


The likelihood of a minority Conservative government could stave off a further fall in sterling when trading begins on Monday, according to analysts.

Prime Minister Theresa May is in talks with the Democratic Unionist Party to support her administration.
The Tories lost their Commons majority in Thursday's general election.
Sterling closed on Friday 1.6% lower against the dollar at $1.2743 and fell 1.4% against the euro to 1.1382 euros.
Societe Generale strategist Kit Juckes said: "You may well see the pound bounce on the optimism ... but it will be short-lived."
David Madden of CMC Markets said Mrs May staying on as prime minister with help from the DUP may assist sterling "a little".
The pound's fall against both the dollar and euro was less dramatic than the drop in the wake of the EU referendum in June last year.
The chances of Mrs May securing a "hard" Brexit have diminished following the loss of the Conservatives' Commons majority, according to some commentators.
George Osborne, the former chancellor, told the BBC he did not believe that most MPs now backed a "hard" Brexit" following the election result.
Panmure Gordon market commentator David Buik said the hung parliament would "require an immediate response to settle for a much softer Brexit".
Former Business Secretary Sir Vince Cable, who is returning to the Commons after regaining Twickenham in southwest London for the Liberal Democrats, said "the whole Brexit approach will have to be rethought".
The DUP campaigned for Brexit, but wants a common travel area between the UK and Ireland and no hard border with the Republic - the UK's only land border with the EU.


The UK economy's growth slowed in the third quarter of the year, weighed down by the performance of the construction and manufacturing sectors.

Gross domestic product grew by 0.5% between July and September, the Office for National Statistics (ONS) said, down from 0.7% in the second quarter.
The rate was also lower than the 0.6% growth predicted by many analysts.
Part of the slowdown was due to the biggest fall in construction output in three years, a drop of 2.2%.
The service sector, the biggest part of the economy, grew by 0.7%.
However, output in the manufacturing sector declined by 0.3%.
"The slowdown is being led by the manufacturing sector, which is seeing a renewed recession as output has now fallen for three consecutive quarters, suffering a 0.3% decline in the three months to September," said Chris Williamson, chief economist at research firm Markit.
"Manufacturing output has so far fallen 0.9% this year. Producers are struggling as weak demand in many overseas markets, notably China and other emerging nations, is being exacerbated by the appreciation of sterling."
We're not immune to the Chinese-led worldwide deceleration. And all the signs are that growth in the fourth quarter of the year will soften again.
This doesn't mean a painful recession is about to rear up and bite us. Annual growth for 2015 is heading for a healthy, if slightly below trend, 2.3%.
But it does mean the ride into 2016 may get slower and bumpier.

The drop in construction output could have been influenced by particularly wet weather in August, the ONS said.
"Overall, the picture of a steady recovery in the UK economy continues and we would now expect GDP growth of around 2.4% for the year as a whole," said John Hawksworth, chief economist at accountants PwC.
According to a poll by news agency Reuters on Monday, economists have pushed back their average forecast of when the Bank of England will start to raise interest rates to the second quarter of 2016 from the first quarter.
This is the first estimate of economic growth for the July-to-September period and makes use of only half the data which will be used for the final estimate.
Chancellor George Osborne said there were more "tough decisions" to come and that his Autumn Statement, due on 25 November, would include "long-term investments for the future".
Sterling fell to $1.5309 after the data, before rebounding to $1.5325, which is 0.2% lower than on Monday.
"The market has pushed the first rate hike way out into the future, so I don't think today's GDP figures are going to have much impact in terms of that timing," said Bank of Tokyo-Mitsubishi currency economist Lee Hardman.


A man has appeared in court charged with poisoning and murdering four young men.

Stephen Port, 40, is accused of killing the men, who he allegedly contacted online via gay websites, between June 2014 and September this year.
Prosecutors told Barkingside magistrates he gave the men large amounts of the drug GHB.
Mr Port, of Cooke Street, Barking, east London, was remanded in custody to appear at the Old Bailey on Wednesday.
The charges relate to the deaths of:
Jack Taylor was a night-duty fork-lift truck driver at a warehouse and was last seen by friends on a night out in Barking on 13 September.
Anthony Walgate is believed to have been a second-year art student at the University of Middlesex.
Daniel Whitworth was an aspiring chef who worked in London Docklands.


York Minster has recruited a new group of bell-ringers after the previous team was controversially disbanded over safeguarding issues.

The 30-strong bell-ringing team was dismissed in October, following a sex assault claim against a member.
The action led to the Minster's 12 bells staying silent on Christmas Day - the first time in more than 600 years.
The new group - which includes some former volunteers - will take over in September.
More on this and other local stories from across Yorkshire
The Chapter said it had taken action against the individual following a police investigation into allegations of indecent assault against young girls.
No charges were brought against the individual and an application for a Sexual Risk Order was refused by magistrates in December 2015.
However, following a risk assessment the Chapter said it "felt that the person presented an ongoing risk and that the potential severity of the risk meant that they could not be reinstated".
It said the bell-ringers refused to accept this decision and so had to be disbanded.
One group of campanologists from Leeds reportedly refused to help out over the Christmas period, in solidarity with their sacked York colleagues.
A new head bell-ringer was appointed in June.
Angela Mitchell was a member of the former bell-ringing team, and said she applied for the job to ensure the Minster's "magnificent bells ring out again each Sunday and for other key occasions".
Speaking at the time, she said: "The recent history of bell ringing at the Minster has been difficult and there is some healing to do."
A Minster spokeswoman said they had received more than 40 applications for the new group.
She added that the recruitment of the new volunteer team had been carried out in line with Church of England safeguarding policies.


National Botanic Garden of Wales research has revealed which plants bees choose for their pollen.

Scientists investigated the species honey bees liked most during spring as part of efforts to protect the bees' environment and better understand their habits.
Peonies, wallflowers, roses, and hyacinth are among the top 10 favourite garden plants.
Favoured wild plants include gorse, willow, hawthorn, oak and dandelion.
Research head Dr Natasha de Vere said bees face a lack of habitat brought about by the loss of hedgerows, woodland and meadows rich in plant species.
Without a healthy and diverse diet, they are unable to withstand pressures from pests, disease and insecticides.
"The main conclusion is that, during the spring, honey bees need native hedgerow and woodland plants, which means we must conserve these habitats," Dr de Vere added.
"The research also tells us that honey bees are supplementing this main diet with smaller amounts from parks and gardens - proving what we do in our own backyard is crucial."
The project - part of the Carmarthenshire garden's Saving Pollinators scheme - identified plant DNA in honey collected from its eight hives and quarter of a million bees.
Of the 437 different types of plants in flower in April and May in the botanic garden, only 11% were used by bees.
Honey bees need access to a wide variety of food throughout spring as they replenish honey stores and feed their young.
The research, carried out by Aberystwyth and Bangor university scientists, found their diet is supplemented by spring-flowering bulbs.
Other favourites include apple and cherry trees, hellebores, oak, holly, and wallflowers.
Researchers now plan to analyse honey from across Wales to understand what bees eat in other parts of the country.


The scene inside Grenfell Tower is "apocalyptic", a coroner told angry survivors calling for more details.

During a three-hour meeting with Dr Fiona Wilcox, survivors asked for information about the missing, but were told the "recovery phase" could last until the end of the year.
Police also faced questions as to why there had not as yet been any arrests.
It comes after officials said all survivors who want to be rehoused had been offered temporary accommodation.
The fire on 14 June killed at least 80 people, although police say the final toll will not be known for many months.
The meeting was held at the Olympia conference centre in West Kensington on Tuesday evening.
Lotifa Begum, from the Grenfell Muslim Response Unit (GMRU), told the Press Association some of those in attendance were "very upset and angry", while several became overwhelmed and had to leave.
Ms Begum said many families "would have appreciated a lot more time and notice" before the meeting was held.
Nabil Choucair fears he has lost six members of his family who lived on the 22nd floor of Grenfell Tower.
Three adults - Nadia, Sirria and Bassam - are believed to have been in the flat, as well as children Zainab, Fatima and Mierna, aged three, 10 and 13.
He told the BBC: "We personally asked where is our family? We want to know are our family's bodies still there and is there anything from them?
"Whatever it is we want to know exactly what it is, do not hide anything. But the answers that were coming back were 'we don't know, we don't know, we don't know'."
It has been reported that people were told before the meeting they would not be allowed to directly question Dr Wilcox or Met Police Commander Stuart Cundy. They were also told to email their questions in by 11:00 BST on Monday.
Meanwhile, the Grenfell Response Team says 139 formal offers of housing have now been made to survivors, after Prime Minister Theresa May promised housing would be offered to those in need by Wednesday.
However, only 14 offers have been accepted and many are still in hotels.
A spokesman for North Kensington Law Centre - which represents more than 100 Grenfell victims - said many of the offers had been unsuitable.
Sid-Ali Atmani said the accommodation his family had been offered was too far away from his daughter's school and not big enough.
"They need to deal with us as victims in an appropriate way and with dignity," he told BBC Breakfast. "We become numbers and we don't have names. This is so frustratingâ€¦ in three weeks they haven't found any solution."
Antonio, who lived on the 10th floor of Grenfell Tower, has turned down two offers of accommodation, saying they do not meet his needs.
"I had a very comfortable and nice flat on the 10th floor," he told the BBC. "I had a very comfortable life, I had a very comfortable home.
"Now the feeling is that they are trying to put us into places just to say 'we have complied with what we said we were going to do'."
Eleanor Kelly, chief executive of Southwark Council and spokeswoman for the Grenfell Response Team, told BBC Breakfast there was an "enormous emotional impact" on the families, so it would take time for permanent moves to take place.
"It is going to take people a long time to really work through where they want to go," she said. "That's why many of the families are choosing to stay in the emergency hotel accommodation for the moment and then make a permanent move.
"We have to understand that and we have to deal with each individual family and their circumstances as appropriately and as sensitively as we can."
Robert Atkinson, leader of the Labour Party at Kensington and Chelsea Council, said decisions about accommodation should be taken by survivors when they are ready - and not just to meet government deadlines.
"It's very important that the survivors are allowed to make their decisions in their own good time and I'm somewhat annoyed at the focus on getting this target met so that the prime minister can say that she has fulfilled her promise," he said.
"I want these arrangements to be made in the timescale and at the pace at which the victims and survivors wish to make these decisions."
In other developments:
It comes amid growing pressure for Sir Martin Moore-Bick - the judge leading the inquiry into the fire - to stand down.
Labour's Emma Dent Coad, MP for Kensington, has described him as "a technocrat" who lacked "credibility" with victims.
On Monday, lawyers representing some of the families also called for him to quit.
Labour leader Jeremy Corbyn stopped short of demanding his resignation, but said he should "listen to residents", while Mayor of London Sadiq Khan warned he must urgently improve relations with the area.
But one senior minister, Lord Chancellor David Lidington, said he had "complete confidence" in Sir Martin, whom he believed would lead the inquiry "with impartiality and a determination to get to the truth and see justice done".

Almost 800 people have attended a public meeting on the future of secondary education in south Powys.

Powys council wants to build a new English-medium school to replace those in Gwernyfed and Brecon by 2019/20.
It is hoped the plan will cut costs and tackle the issue of surplus places.
But many are concerned about the impact closure will have on the community, children's education and the distance some will have to travel to get to the next nearest school.
Some have even suggested this move will mean students who could attend Gwernyfed in future will be forced to go to school over the border in Hereford.
Ian Charlesworth, chairman of governors at the 450-pupil Gwernyfed High School, said: "If the school closes, it's so deeply rooted in the local community, we fear for the future of the community.
"People are frightened what it might mean once this place isn't here providing the sports facilities and the drama studio, on top of the children having to moving elsewhere to socialise."
Powys council said it had to make these changes because of a surplus in school places and to ensure better funding for the future of secondary education in south Powys.
Councillor Arwel Jones, the authority's education spokesman, said: "Any school closure is a worry for parents in the community.
"But there's around 1,500 less pupils in secondary education in Powys compared to six years ago.
"Obviously the funding to schools is linked to this and therefore the choice of subjects available.
"There is also room for improvement in standards, so the idea is to have a concentrated mass of students in one school to attract the best teachers."
The public consultation on the proposed changes ends on 22 May.


Iran has agreed a long-term deal on its nuclear programme with six world powers, capping 12 years of on-off negotiations and potentially ending one of the world's most serious crises.

The long-running dispute has widened divisions between Iran and the West, but a comprehensive accord might bring down diplomatic barriers.
Multiple deadlines were missed as negotiators sought to build on an interim deal struck in November 2013 after the election of the moderate Iranian President Hassan Rouhani, who promised to end his country's international isolation.
US President Barack Obama said the agreement announced in Vienna marked "one more chapter in our pursuit of a safer, more helpful and more hopeful world".
Under the Joint Comprehensive Plan of Action (JCPOA), Iran has agreed with the so-called P5+1 - the US, UK, France, Russia, China and Germany - to significantly limit its sensitive nuclear activities.
Iran will reduce its stockpile of enriched uranium - used to make reactor fuel, but also nuclear weapons - by 98% to 300kg (660lb) for 15 years. It will also cut by two-thirds to 5,060 the number of centrifuges installed to enrich uranium for a decade.
Sanctions imposed the UN, US and EU will be lifted as Iran's compliance is verified by the the International Atomic Energy Agency (IAEA), and more than $100bn (Â£64bn) in assets frozen overseas will be released. Should any aspect of the deal be violated, the sanctions will "snap back".
Guide to the Iran nuclear deal
Years of distrust and suspicion have made the crisis over Iran's nuclear programme hard to solve.
The P5+1 want to be satisfied that Iran won't have the capacity to make a bomb in less than a year if it decided to - the so-called "break-out" time.
Iran for its part says it does not want a nuclear bomb, but insists on exercising its right to run a peaceful nuclear industry. It also wants crippling international sanctions lifted quickly.
Many countries do not believe Iran's declared intentions, and there is fear of what Iran might do with a nuclear weapon, and of the prospect of a nuclear arms race in one of the world's most unstable regions.
Iranian ambitions breed scepticism and fear in Israel
Lebanon pivotal to Iran's reach across Middle East
It looks to some like Iran has been singled out - after all, many countries have nuclear programmes and at least eight possess nuclear weapons. The reason why such attention has been focused on Iran is because it hid a clandestine uranium enrichment programme for 18 years, in breach of the Nuclear Non-Proliferation Treaty (NPT).
As a result, the UN Security Council passed six resolutions requiring Iran to stop enriching uranium, a process that can ultimately produce the fissile material for a nuclear weapon.
Iran agreed to suspend parts of its nuclear programme under a temporary agreement in November 2013 in return for some sanctions relief, but this was a stop-gap deal, not an end to the crisis.
The international community was also worried about unanswered questions surrounding possible military dimensions to Iran's nuclear programme.
A 2007 US intelligence report said Iran had a nuclear weapons programme, but "halted" this in 2003.
The global nuclear watchdog, the International Atomic Energy Agency (IAEA), has been investigating this in parallel to the main nuclear talks, but says Iran has not provided enough information about its past activities. These include possible nuclear-related tests at a secret military site, where Iran has barred IAEA inspectors.
Iran says the international community is displaying double standards by not doing anything about its arch-foe Israel, which is widely believed to have a nuclear arsenal - though Israel has neither confirmed nor denied this. Israel however, like nuclear-armed India and Pakistan, is not a signatory to the NPT.
Mapping Iran's key nuclear sites
Since Iran's undisclosed nuclear activities came to light, the country has been hit by a raft of sanctions - by the UN, EU, US and other countries.
These include a ban on the supply of heavy weaponry and nuclear-related technology to Iran, a block on arms exports, asset freezes, travel bans, bans on trade in precious metals, and bans on crude oil exports and banking transactions, among others.
The sanctions have contributed to a fall in the value of the Iranian riyal and to rising inflation, with the cost of basic foodstuffs and fuel soaring. This has hit ordinary Iranians, with some rare protests reported.
Under the 2013 interim deal, Iran got some sanctions relief in return for curbing its enrichment activities.
The comprehensive accord will see oil and financial sanctions phased out gradually as the IAEA confirms Iranian compliance. However, the UN weapons embargo and the ban on buying missile technology will remain in place for several years.
What are the sanctions on Iran?
How ordinary Iranians see the nuclear talks
A deal which leaves Iran with any capacity whatsoever to build a bomb has alarmed Israel and Iran's neighbours in the Gulf.
Iran believes Israel should not exist. Israel sees a nuclear Iran as a major threat to it and the wider world.
Israel's Prime Minister Benjamin Netanyahu said the comprehensive accord was a "bad mistake of historic proportions" that would allow Iran to "continue to pursue its aggression and terror in the region".
He has previously warned that Israel will do everything necessary to thwart the prospect of Iran developing nuclear weapons.
Saudi Arabia, the Sunni-ruled regional rival to Shia Iran, also fears a compromise deal will not stop Iran eventually getting a nuclear bomb. Saudi Arabia also worries that an end to sanctions will embolden and strengthen Iran economically and militarily.
Both Israel and Saudi Arabia, key US allies in the region, feel Washington is putting a deal with Iran before their security needs.
Although a deal has been agreed, it still does not mean the crisis is over.
While an agreement might defuse the stand-off between Iran and world powers, Israel and Saudi Arabia have warned it could fuel a nuclear arms race in the Middle East. Under this scenario, countries such as Egypt and Saudi Arabia could seek to equip themselves with nuclear weapons before Iran gets a chance to.
There are also strong opponents to a deal in both Iran and the US. In Iran, hardliners will portray the deal as a defeat for Iran, while in Washington members of Congress, where scepticism is strong, will have to approve the deal before US sanctions can be lifted.
US President Barack Obama himself has said he will support fresh sanctions against Iran if it does not uphold any agreement.
Are Iranâ€™s Sunni neighbours about to race for The Bomb?


Voters in the UK prepare to go to the polls on Thursday in an election seen as one of the closest-fought in years.

But why should the vote be of interest beyond England, Scotland, Wales and Northern Ireland?
A third of eligible voters in the UK are themselves unlikely to bother to turn up and vote so why should anyone else care? Here are six good reasons.
In brief, because Britain is still a very rich and powerful country that millions of people visit or move to every year; because all its various internal divisions of class, region, wealth, race make it a fun and culturally vibrant place; and, for goodness sake, because nobody has the faintest idea who is going to win.
What the latest national polls say
Build a parliamentary majority with our game
The UK continues to be one of the permanent members of the UN Security Council, and a nuclear power with the fifth largest defence budget in the world. But at this election much of that is at stake.
At least two parties, the Scottish National Party and the Liberal Democrats, not only oppose the renewal of the UK's nuclear deterrent but may have the influence to do something about it.
Then there's the fundamental question of Britain's relationship with Europe, with David Cameron promising an in-out referendum on membership of the European Union by the end of 2017, if he remains prime minister.
And let's not forget that the rise of the Scottish National Party is sure to raise at some point the question of independence and the prospect of a somehow diminished United Kingdom.
Could a UK without Scotland or without nuclear weapons or outside the EU still command a seat at the UN's top table, and what would Nato and the US think? These are not entirely fanciful outcomes but real possibilities.
EU holds it breath ahead of UK vote
Every year since 1998, net migration to Britain - the difference between those leaving the country and coming into it - has exceeded 150,000.
In many of those years it has even been above a quarter of a million people.  Unsurprisingly, perhaps, immigration has been a big issue at this election just as it was in 2010.
One party, UKIP, is saying Britain must take back control of its borders by leaving the EU, thereby ending free movement for half a billion Europeans, and by introducing an Australian-style points system for judging who should and who shouldn't come in.
UKIP are not going to win the election, but it's worth remembering that the Conservatives are also hoping to discourage EU nationals from coming here through changes to the benefits system, while Labour is promising to crack down on companies that use cheap foreign labour.
Access to the UK is likely to change in some way or another.
Statisticians are not entirely sure, but the UK is still the fifth or sixth biggest economy in the world and the City of London rivals New York as the global centre for financial services.
Apart from the Conservatives (and even they've been rather shy) this election campaign has been pretty hostile to the wealthy and especially those who are foreign and rich.
The opposition Labour party, for example, is promising to raise taxes on expensive properties and to start taxing the global earnings of wealthy foreigners in London, not to mention further bank taxes and an increase in corporation tax.
So there is plenty to think about there for those in the boardrooms of international companies.
The UK's 2.6% growth rate last year made it one of the fastest growing economies in Europe.  Unemployment is at 5.6% compared with a eurozone average of 11.3% and the current government's economic strategy was endorsed by International Monetary Fund head Christine Lagarde.
But Britain's economic problems are far from solved. It still imports more than it exports and still has an enormous budget deficit of Â£87bn, or 5.5% of GDP.
It's how to tackle this that forms the biggest, most significant, but barely discussed divide at this general election.
Put simply, the Conservatives are promising to get rid of the deficit by the end of another five years in government, exclusively through spending cuts. Labour is committed only to the much vaguer target of reducing borrowing.
The highly respected Institute for Fiscal Studies has accused both parties of providing the electorate with at best an incomplete picture of what to expect.
What are the top issues for each political party at the 2015 general election?
Policy guide: Where the parties stand
My last effort to persuade you of this election's significance is that it's just a cracking story with something very odd, possibly even momentous, about to happen.
Most striking, of course, is Scotland.  Although it voted No to independence last September, the whole referendum campaign electrified support for the Scottish National Party and the SNP is looking at a landslide on Thursday.
In the short term, at the very least, it could mean the SNP having a huge say in who forms the next UK government.
But beyond that it will surely at some point revive the question of independence. And what will being wiped out in its Scottish heartlands do for the psyche and long-term prospects of the Labour Party?
More broadly nationwide, Britain's two-party system appears under severe threat, with the distinct prospect that between them Labour and the Conservatives will struggle to gain two-thirds of the votes cast. Compare that with their near 90% vote share just 50 years ago.
Will it be a blip, or is Britain heading for an era where, as in Europe, government by coalition is more the rule than the exception?

Google says it has stopped a phishing email that reached about a million of its users.

The scam claimed to come from Google Docs - a service that allows people to share and edit documents online.
Users who clicked a link and followed instructions, risked giving the hackers access to their email accounts.
Google said it had stopped the attack "within approximately one hour", including through "removing fake pages and applications".
"While contact information was accessed and used by the campaign, our investigations show that no other data was exposed," Google said in an updated statement.
"There's no further action users need to take regarding this event; users who want to review third party apps connected to their account can visit Google Security Checkup."
During the attack, users were sent a deceptive invitation to edit a Google Doc, with a subject line stating a contact "has shared a document on Google Docs with you".
The email address hhhhhhhhhhhhhhhh@mailinator[.]com was also copied in to the message; Mailinator, a free email service provider has denied any involvement.
If users clicked on the "Open in Docs" button in the email, they were then taken to a real Google-hosted page and asked to allow a seemingly real service, called "Google Docs", to access their email account data.
By granting permission, users unwittingly allowed hackers to potentially access to their email account, contacts and online documents.
The malware then e-mailed everyone in the victim's contacts list in order to spread itself.
"This is a very serious situation for anybody who is infected because the victims have their accounts controlled by a malicious party," Justin Cappos, a cyber security professor at NYU, told Reuters.
According to PC World magazine, the scam was more sophisticated than typical phishing attacks, whereby people trick people into handing over their personal information by posing as a reputable company.
This is because the hackers bypassed the need to steal people's login credentials and instead built a third-party app that used Google processes to gain account access.
The Russian hacking group Fancy Bear has been accused of using similar attack methods, but one security expert doubted their involvement.
"I don't believe they are behind this... because this is way too widespread," Jaime Blasco, chief scientist at security provider AlienVault, told PC World.
Google said the spam campaign affected "fewer than 0.1%" of Gmail users. That works out to about one million people affected.
Last year, an American man pleaded guilty to stealing celebrities' nude pictures by using a phishing scam to hack their iCloud and Gmail accounts.
And in 2013, Google said it had detected thousands of phishing attacks targeting email accounts of Iranian users ahead of the country's presidential election.


A plan to restrict West African presidents to two terms in office has been dropped for the time-being by heads of state.

They discussed the proposal to impose limits at a regional summit.
Togo and The Gambia, both with presidents who have been in power for more than two terms, opposed the idea, diplomats say.
The third-term issue has caused a lot of controversy in several African states in recent years.
Burkina Faso's President Blaise Compaore was forced out of office last year after trying to change the constitution so he could run for a third term.
In East Africa, there have been weeks of protests and a failed coup after Burundi's President Pierre Nkurunziza announced plans to seek a third term in office.
The constitutions of most West African states already impose a two-term limit.
The proposal discussed at Tuesday's summit of the regional body Ecowas in the Ghanaian capital, Accra, was supposed to formalise this across the region.
If a popular referendum on presidential term limits was held across the region, there is little doubt that people would vote in favour of it.
Since the president of Burkina Faso was overthrown last year for trying to change the constitution so he could seek re-election, this has become a big regional issue.
However, some West African leaders argue that each country has a different political context and there cannot be a blanket ruling.
Optimistic souls would say that it is already a step forward that presidential terms are being discussed at an Ecowas summit.
But imposing a two-term limit limit requires unanimity among West African leaders, and there is still a long way to go to achieve that.
The UN representative in West Africa Mohammed Ibn Chambas backed the plan and said it had been triggered by the failed attempt by President Compaore to change the constitution to allow him to run for a third term.
But the BBC's Sammy Darko in Accra says that it was not adopted as Togo and The Gambia had reservations.
"This dissenting view became the majority view at the end of the day," the Reuters news agency quotes Ghana's Foreign Minister Hanna Tetteh as saying.
The plan has now been deferred for further consultation.
Togo's President Faure Gnassingbe has been in power since 2005 and won a third term in office last month.
Gambian President Yahya Jammeh is reaching the end of his fourth term in office after coming to power in a coup in 1994.
President Jammeh told the BBC in 2011 that presidents should be judged on what they do in power not by the length of time they have been in office.
"I will deliver to the Gambian people and if I have to rule this country for one billion years, I will, if Allah says so," he said.


Jamie Vardy has been likened to Dutch legend Marco van Basten following his stunning strike against Liverpool.

The Leicester City frontman enhanced his growing reputation with a 30-yard shot that flew past Reds keeper Simon Mignolet on Tuesday.
It was the first of two goals for the England international in a 2-0 win.
Speaking ahead of Saturday's match with Manchester City, Leicester boss Claudio Ranieri said the goal was "amazing - you can put him with Van Basten".
Dutch great Van Basten scored some brilliant goals in his career, including a memorable volley against the USSR in the final of the 1988 European Championship.
Running away from goal and towards the byeline on the right-hand side of the penalty area, he showed amazing technique and awareness to fire his volley over goalkeeper Rinat Dasayev from a tight angle.
The strike helped give the Netherlands a 2-0 win in the final.
Radio 5 live football daily - Ranieri assesses Vardy's form.
Meanwhile, Spurs manager Mauricio Pochettino says Vardy is as good as his own Harry Kane and Manchester City striker Sergio Aguero.
Vardy is the Premier League's top scorer this season with 18, three above fellow England striker Kane in joint second.
Argentine Aguero, who cost City a reported £38m in 2011, won last season's Golden Boot with 26 goals.
"Today Vardy and Kane show big quality and the same quality as Aguero," Pochettino said.
"They are all different and come from different circumstances but today Vardy and Kane are at the same level as Aguero."

Tenants who were facing eviction from their homes in Leith are being allowed to stay after a housing association was found to buy the properties.

The flats in Lorne Street, owned by The Miss Agnes Hunter Trust, are being sold to Places for People Scotland.
The trust said the costs of the 92 flats were diverting funds from the causes it was set up to support.
Residents, who feared for 18 months they might lose their homes, said it was "absolutely fantastic news".
Places for People Scotland confirmed the sale of the property portfolio would not affect the lease agreement and rights of the tenants.
The Miss Agnes Hunter Trust is a grant-making charitable trust set up by her will in 1954 to provide financial help to charitable organisations which support health and social welfare in Scotland.
Walter Thomson, chairman of the Miss Agnes Hunter Trust, said: "The trustees have considered the offer carefully and are confident that Places for People Scotland and its associated organisation Castle Rock Edinvar have the expertise and resources to take management of the property portfolio forward and that the sale is in the best interests of the tenants.
"We have written to the tenants informing them of the sale and advising that The Miss Agnes Hunter Trust will remain their landlord until the settlement date of 28 November 2016 after which tenancies will transfer to Places for People Scotland.
"The sale will enable the Trustees to carry out the specified wishes of Miss Hunter by maintaining the financial grants to registered charities which support people suffering from arthritis and cancer, physical disability and mental health problems or learning disabilities, or which provide youth education and training for disadvantaged people.
"Currently grants amount to around Â£350,000 each year."
Melanie Weigang, 48, secretary of Lorne Street Association, told the BBC Scotland news website: "This is absolutely fantastic news and a huge relief.
"This has been dragging on forever and to find out before Christmas that we are not going to be evicted is just brilliant.
"There are a lot of elderly people who have been living in Lorne Street for decades and families use the local school so they did want to move from their homes and the area."
Alister Steele, managing director of Castle Rock Edinvar/Places for People Scotland, has also written to the tenants introducing their new landlord.
He said: "We are pleased to be able to finally announce the purchase of the 92 properties from Agnes Hunter Trust and end a period of uncertainty for the residents.
"We have a proud track record in investing in Edinburgh's housing stock and in managing the purchase of tenanted housing.
"We will now begin a dialogue with the residents to give reassurance on our commitment to the future of the properties and to discuss our services and investment plans.
"We would like to take this opportunity to thank the Scottish government and City of Edinburgh for their help on this matter."
Deidre Brock MP said: "I'm thrilled to bits to hear this news.
"What a fantastic day for the tenants of Lorne Street who have been worried about eviction since June last year."
Cammy Day, of City of Edinburgh Council, said: "I am really pleased that we have reached a positive solution for the residents of Lorne Street.
"The council and our partners have been working closely with tenants since they first approached us over a year ago with concerns that they might be made homeless."


The UK's voluntary living wage, as promoted by the Living Wage Foundation campaign group, is to be increased by 40p an hour.

The new rate will rise to £8.25 per hour, from its current £7.85.
For those living in London, the rate will rise by slightly less - 25p - to £9.40 an hour, the city's Mayor, Boris Johnson, announced.
More than 2,000 businesses, with almost 70,000 workers, are signed up to the scheme.
Currently, the government's national minimum wage stands at £6.70 per hour, but a new National Living Wage for over-25s of £7.20 will be introduced in April next year.
"Today we are celebrating those 2,000 responsible businesses that are voluntarily paying the living wage to their staff," said Sarah Vero, director of the Living Wage Foundation.
"These employers are not waiting for government to tell them what to do. Their actions are helping to end the injustice that is in-work poverty in the UK now," she added.
As with the government's minimum wage, employers have six months to implement the new pay level.
It follows a report on Sunday from accountants KPMG that claimed almost six million workers in the UK were paid less than the living wage, with part-time, female and young workers being most likely to earn below that figure.


Disgraced entertainer Rolf Harris has been jailed for nearly six years for 12 indecent assaults against four girls - including one aged just seven or eight.

Mr Justice Sweeney said Harris, 84, had taken advantage of his celebrity status and had shown "no remorse".
The sentence of five years and nine months has already been referred to the Attorney General's Office under the "unduly lenient sentence scheme".
One victim said the abuse had taken away her "childhood innocence".
Harris, who was found guilty of offences that took place between 1968 and 1986, was told by the judge he had "no-one to blame but himself".
He displayed no emotion and stared straight ahead as he was jailed.
Before Harris was sentenced, prosecutors said he would not stand trial over allegations he had downloaded sexual images of children.
They had claimed Harris had indecent images of children, as part of a larger collection of adult pornography, but decided it was not in the public interest to prosecute him.
During sentencing, the judge said Harris "clearly got a thrill" from committing some of the assaults on his four victims while "others were present or nearby".
He said Harris touched the youngest victim intimately when she approached him for an autograph in Portsmouth, while another was "groped" at an event in Cambridge.
As well as the girl who was aged seven or eight, Harris's victims were two young teenagers and a childhood friend of his daughter Bindi. He abused his daughter's friend between the ages of 13 and 19.
The judge said Harris "fancied" this victim and assaulted her in her home and his, breaching the "trust that her parents had placed in you".
He said the assaults resulted in the teenager suffering panic attacks, anxiety and led to her becoming an alcoholic, saying she had "suffered severe psychological harm".
Speaking after sentencing, she said the jail term was "immaterial" but the verdict was "what I wanted, what I went to court for".
She added: "I do hope that women will come forward now, celebrity or not."
Some of the sentences will be served at the same time, making a total of five years and nine months.
Harris is likely to serve half of the sentence in prison and was told he would not have to pay compensation to his victims. However, the judge said he could have to pay the costs of the prosecution.
A spokeswoman for the Attorney General's Office did not say who had referred the sentence as being "unduly lenient" but said it "only takes one person to trigger the process".
The sentence must be considered within 28 days for possible referral to the Court of Appeal, the spokeswoman added.
Harris was prosecuted based on the law at the time of his offences, when the maximum sentence for indecent assault was two years in prison, or five years for victims under 13.
Two of his victims were in court for the sentencing, which saw members of the press and public fill the public gallery and watch from an overspill court via a video feed.
Harris's daughter Bindi was with him in court but his wife Alwen, who has been consistently present throughout the trial, did not attend.
In court
Jane Peel, BBC News correspondent
The queue outside court two began to form at 07:45 BST - more than two hours before the hearing was due to begin.
Rolf Harris had started his final journey to Southwark in a boat from his house on the Thames, in Bray, Berkshire, but he arrived as usual in a car.
His daughter Bindi was with him but there was no sign of his frail wife, Alwen.
Perhaps in contrast to his mood, he wore a jazzy, multi-coloured tie and a light grey suit.
He had brought with him a similarly bright suitcase with a stripy design. Harris knew he would be going to prison. The only question was for how long.
He had been allowed to stay seated, but was told to stand as Mr Justice Sweeney announced that he would be jailed for five years and nine months.
There was no visible reaction from him or his relatives who were in court as he was led to the cells by two dock security officers.
Peter Watt, of the NSPCC, said: "It sends a message that no-one is untouchable and justice can come at any time."
Alan Collins, of law firm Slater and Gordon, told the BBC his firm had been contacted in "recent days" by people making new allegations against Harris.
He said the calls had come from both the UK and overseas, and lawyers would meet the complainants in the coming days.
Earlier, the court heard impact statements from the four victims, including from the childhood friend of Harris's daughter.
Reading out the statement, prosecutor Esther Schutzer-Weissman said the abuse had "haunted" the victim and left her feeling "dirty, grubby and disgusting".
The statement from the victim who had been seven or eight said the abuse had taken away her "childhood innocence".
Harris indecently assaulted a waitress at a charity event in Cambridge when she was aged 13 or 14, who said the star had "treated me like a toy".
One woman told the BBC she met Harris when she was 18 and he was "very kind, very nice" - but then "sexually abused" her.
The woman, who cannot be named for legal reasons, gave evidence in the trial but the attack in Malta was not the subject of a prosecution because at the time of the incident the offence was outside the jurisdiction of a UK court.
She said Harris led her into a room to show her his artworks.
"He closed the door and then he pushed me up against the wall," she said.
"It was quite intimate, it was forceful and it was scary... I don't know how long it took to be quite honest but I couldn't get away.
"And then he suddenly just stopped, he hugged me and said he was sorry."
She said she had thought she was going to be raped, but she did not report it because she did not think anyone would take her seriously.


Castleford Tigers ran in seven unanswered tries against Wakefield to record their first Super League win of the season.

Stuart Howarth opened the scoring for Wakefield before Denny Solomona, Ben Roberts and Luke Dorn tries put the hosts 18-6 up at the break.
Oliver Holmes went over with Tigers' first attack of the second half.
Further Solomona, Holmes and an Adam Milner try completed the resounding win for the hosts.
The Tigers shared the spoils with Hull KR in their season opener last week, but there was no sign that Wakefield would be given the chance to fight their way back into the contest as Rovers were.
Howarth gave the Wildcats the ideal start with the games' first points, but that was the first and last time they led as Solomina's try was converted by Luke Cale to lock scores up after six minutes.
Roberts then went in to edge the hosts ahead, with Dorn then dummying brilliantly to cross for Castleford's third try.
Holmes quickly added to the advantage after the break, with Milner touching down before Solomona completed his brace.
Junior Moors fended off a series of tacklers and dished the ball off for Holmes to complet the win and consign Wakefield to a second defeat this season.
Castleford: Dorn; Monaghan, Crooks, Webster, Solomona; Roberts, Gale; Lynch, McShane, Millington, O. Holmes, McMeeken, Jewitt.
Replacements: Milner; Moors, Massey, Cook.

Police and art experts are checking 22 artworks found in southwest Germany which may be linked to the huge hoard of art treasures seized in Munich.

The regional broadcaster SWR says most of the 22 works are valuable paintings. Some may have been looted by the Nazis.
On Saturday Paris Match magazine published a photo of a man alleged to be Cornelius Gurlitt, the Munich collector. He was spotted in Munich.
So far 25 of the Munich works have been listed on the website www.lostart.de.
On Saturday police in Baden-Wuerttemberg removed 22 artworks from a flat in Kornwestheim, a town near Stuttgart. They are now being examined at a secret location.
The flat belongs to an 80-year-old man, who is a brother-in-law of Cornelius Gurlitt and, like him, a former art collector.
Four of the paintings are believed to have been acquired from Mr Gurlitt, SWR says.
Stuttgart police said the 80-year-old was not suspected of any crime and had himself contacted the police to get his collection stored in a safe place. The intense media interest in the Gurlitt case had made him anxious, SWR reported.
More than 1,400 artworks were found at the Munich flat of Mr Gurlitt in March 2012.
The total value has been estimated at about 1bn euros (Â£846m; $1.35bn).
German authorities showed images of some of the works, by famous artists such as Marc Chagall, Otto Dix, Max Liebermann and Henri Matisse. But they have not yet published a full list and the officials stressed that a painstaking investigation is now under way.
Some of the Munich works may have been stolen from Jews and kept in Nazi collections during 1933-1945.


The Northern Ireland Secretary, James Brokenshire, has said he will "reflect" on his next move after talks failed to restore a power-sharing executive.

Sinn Féin's Michelle O'Neill said the deadlock was a "consequence" of the Democratic Unionist Party's (DUP) support for the Tory government.
The failure to reach a power-sharing deal was a "monumental failure" by Theresa May, she said.
DUP leader Arlene Foster said her party will "keep working over the summer".
Northern Ireland has been without a functioning devolved government since January, when the coalition led by the two biggest parties, the DUP and Sinn Féin, collapsed over a green energy scandal.
In a statement, Mr Brokenshire said the issues dividing the parties "cannot be resolved quickly enough to enable an executive to be formed" soon.
He added that the government would "not forget our responsibilities to uphold political stability and good governance".
"I will reflect carefully in the coming days on any further steps which may be required to support the continued effective provision of public services in Northern Ireland."
The secretary of state has dropped a hint that he is now considering passing a budget from Westminster.
Northern Ireland's civil servants have been controlling finances for several months.
But, to date, they have only had 75% of the block grant allocation.
A budget bill would change that - giving access to all £10bn of annual day-to-day spending.
It would also split the cash among individual departments like health and education.
However, it still leaves the question of who decides what polices or projects to spend it on.
These can be political decisions for ministers - not civil servants.
BBC NI's Political Editor Mark Devenport said a source had told him it was unlikely Mr Brokenshire would legislate for a budget before the Autumn.
The Irish Foreign Affairs Minister, Simon Coveney, urged the parties to "reflect on how progress can best be made".
Mrs Foster said the DUP wanted to see devolution restored at Stormont and would not abandon the talks process.
"I know people think politicians don't work over the summer, but actually we will keep working over the summer months to try to get agreement and come back again in the autumn," she added.
Mrs O'Neill said lack of a power-sharing deal was "a consequence of the DUP supporting the prime minister and, in turn, the prime minister supporting the DUP".
"We want to see these institutions restored but we need the executive to work on a sustainable basis, on the basis of fairness and equality," she said.
The SDLP's Nichola Mallon said her party's attempts to put forward solutions to the disputed issues were rebuffed by the DUP and Sinn Féin.
"Parties are putting their own narrow self-interest ahead of the interests of the people of Northern Ireland.
"Now people across Northern Ireland are facing weeks upon weeks of further political paralysis."
Robin Swann, the Ulster Unionist Party leader, said he was "failing to see any positives".
"The two largest parties have received the largest mandates they've ever had but they're failing to deliver for the people of Northern Ireland," he added.
The "deep, deep political impasse" between the DUP and Sinn Féin was leaving Northern Ireland's public services in "real jeopardy", according to the Alliance Party's Stephen Farry.
He urged the parties to "come to their senses", saying they needed "a sense of proportion and perspective in that particular regard".
"People are going to suffer as a consequence unless action happens."
On Monday, Northern Ireland Secretary James Brokenshire said a deal to restore power sharing was still achievable.
Mr Brokenshire told MPs that legislation to enable a new executive could come as early as this week, but cautioned: "Time is short".
He warned that if no agreement was made he would be forced to pass a budget.
He said he would not call an assembly election immediately but would keep his options under review; he could have reintroduced direct rule from Westminster.
The most significant sticking points between the parties are disagreements over an Irish language act, same-sex marriage, a Bill of Rights and measures to deal with the legacy of Northern Ireland's Troubles.
In January, the late Martin McGuinness, of Sinn Féin, resigned in protest over the DUP's handling of an inquiry into the Renewable Heat Incentive scheme.
His party had demanded that DUP leader Arlene Foster step aside temporarily to allow an investigation into the scheme she set up, but Mrs Foster refused.
Over the past six months, and during two elections at Stormont and Westminster, the two parties have remained deadlocked over a number of issues.


Aston Villa boss Roberto di Matteo says they need to time to turn around their fortunes this season.

Di Matteo's side bounced back from successive defeats with a 3-0 win over Rotherham but conceded a late equaliser against Huddersfield on Tuesday.
"We're a work in progress. The players that have come in need to understand how we want to play," the Italian said.
"It's going to take time but it's a shame because I thought we deserved a bit more [against Huddersfield]."
Villa were beaten 1-0 by Sheffield Wednesday in their first game back in the second-tier since 1988 and were knocked out of the EFL Cup by League Two side Luton.
Rudy Gestede scored twice in their win against the Millers on Saturday, but Villa were forced to settle for a point against Huddersfield when keeper Pierluigi Gollini's clearance bounced off Michael Hefele's back into an empty net in the 86th minute.
"There is a lot of improvement in the team in the weeks that we have worked together," the Villa manager told BBC WM.
"I think it's games like this you need to be able to score a second goal to kill the game or be able to see it out and get the three points."


The Stick Man has picked up two prizes at the British Animation Awards, including one for Martin Freeman.

The actor won best voice performance for his acting in BBC One's Christmas-themed film, which also won best use of sound.
The Amazing World of Gumball, the children's series on Cartoon Network, also won two awards.
Shaun The Sheep: The Movie won the biggest award of the night - best long form animation.
The character of Shaun The Sheep started life in a television series, as part of a spin-off from the Wallace and Gromit franchise.
The movie version was released last February and went on to take more than $100m (Â£69.9m) worldwide.
The awards, which are held every two years, were handed out at a ceremony at London's BFI Southbank on Thursday evening.
They honour British animators across a variety of categories including short films, animated graphics for film and television, children's series, music videos and commercials.
Teeth, a film which follows the story of a man whose life events are chronicled through the loss of his teeth, prevailed in the short film category.
Cartoon Network's The Amazing World of Gumball: The Shell picked up best children's series and the children's choice award.
The best music video category was won by Manchester-based band James, who won for the video to their single Moving On.
Elsewhere, the award for best TV/film graphics was won by Mattias Hoegg and Callum Cooper for their work on the Guardian Newspaper's The Power of Privacy documentary.
Animated Minds: Stories of Postnatal Depression was the winner in the best commissioned documentary animation category.
BAA Director, Jayne Pilling said: "It's 20 years since these awards began and we never cease to be bowled over by the sheer creativity and innovation in the British animation industry.
"The incredibly difficult decisions that our panels had to make to choose the winners prove that the animation industry is in better health than it's ever been."
There are also two awards handed out at the ceremony every two years to new talent in animation.
This year, they were won by Katie Lenton and Sarina Nihei, who took home the awards for best undergraduate film and best postgraduate film respectively.

A pensioner who killed a three-year-old girl weeks after being told to stop driving because of poor eyesight has been jailed for four years.

Poppy-Arabella Clarke and her mother Rachel were struck by John Place's car as they crossed Chester Road in Sutton Coldfield, Birmingham, in July 2016.
Her mother was also seriously injured in the crash.
Place, 72, admitted causing death by dangerous driving and causing serious injury by dangerous driving.
At the time of the incident the traffic lights were on red and the green light was flashing for pedestrians, police said.
More on this and other Birmingham and Black Country stories here
Place, of Bakers Lane, Sutton Coldfield, was jailed at Birmingham Crown Court.
He told police he was not wearing his glasses and that he had not seen the red light or the crossing itself.
In a family statement, Poppy-Arabella's parents Rachel and Phil said their daughter had spent the morning "playing with mummy" and "was excited to be heading to nursery to see her friends".
The family's lawyer called for a "Poppy-Arabella's law" requiring medical professionals to report people unfit to drive to the DVLA.
The statement added Place "did not swerve, he did not brake and he did not stop".
He only stopped when flagged down by another driver.
Poppy-Arabella's parents are calling for a change in the law, requiring medical professionals to report people who are unfit to drive the DVLA.
Their call follows the introduction in 2013 of "Cassie's Law", named after Cassie McCord, who was 16 when she died in 2011.
Colin Horsfall, 87, mounted a pavement at speed in Colchester, Essex, striking Cassie, having failed a police eye test days earlier.
Police had been in the process of getting Mr Horsfall banned after he refused to surrender his licence.
A campaign by Cassie's mother Jackie led to a change in the law, giving police more power to revoke driving licences.
Police previously had to write or fax a request for licence removal, but the change means they can now telephone or email, with a dedicated email for police to use.
Email confirmation from the DVLA means the licence is revoked so police can stop someone driving there and then.
A police spokesman said Poppy-Arabella's parents "continue to suffer enormously from their loss".
He added: "Place should not have been driving that day as, quite simply, his vision was severely impaired."
Paying tribute to his daughter, Poppy-Arabella's father Phil said: "We will miss her forever, we will love her for always.
"We have been left with a life sentence without our little girl, whose entire life was stolen from her in a fraction of a second."
Place has also been disqualified from driving for five years from the date of his release from prison.
At a previous hearing, the court heard Poppy-Arabella's parents were unable to have any more children and said Place had so far shown them no remorse.


A man has been charged with attempting to murder a woman and a six-year-old girl following a fire in the West Midlands.

Daniel Watkins, from Alcester in Warwickshire, has been charged in connection with a fire in Cradley in the early hours of Friday.
The woman, aged 34, and the girl were treated for the effects of breathing in smoke, police said.
Mr Watkins, 34, from Smiths Close, is due before magistrates in Dudley later.


England forward Maro Itoje was named breakthrough player of year and compatriot Sarah Hunter won women's player of the year at the World Rugby awards.

Itoje, 22, helped England complete the Six Nations Grand Slam and was part of the squad that secured a 3-0 series whitewash of Australia down under.
England captain Hunter, 31, was ever-present throughout 2016.
New Zealand fly-half Beauden Barrett won the men's player of the year award.
Barrett, 25, is the fifth successive player from the world champion All Blacks to receive the award, after Dan Carter (2012 and 2015), Kieran Read (2013) and Brodie Retallick (2014).
Itoje, his Saracens and England team-mates Owen Farrell and Billy Vunipola, New Zealand's Dane Coles and Ireland's Jamie Heaslip were also shortlisted.
Itoje is currently injured and missed England's 37-21 win over South Africa on Saturday.
Steve Hansen was named coach of the year, and his All Blacks were team of the year having set a new record for winning 18 successive Tests.
South Africa's Seabelo Senatla and Australia's Charlotte Caslick were respectively the men's and women's sevens players of the year.

The highest-ever wave detected by a buoy has been recorded in the North Atlantic ocean, the World Meteorological Organization has said.

The 19-metre (62.3ft) wave happened between Iceland and the United Kingdom, off the Outer Hebrides.
It was created in the aftermath of a very strong cold front with 43.8 knot (50.4mph) winds on 4 February 2013.
The WMO, which released the data, said the previous record was 18.275 metres (59.96ft) in December 2007.
That wave was also in the North Atlantic.
It is not the biggest-ever recorded wave, however. In 2002 a ship spotted a 29-metre (95 ft) North Atlantic wave.
In 2014, the M4 Donegal buoy recorded a 23.4 metre wave, but the WMO said the new record was based on "significant wave height" which required certain measuring methods and observing periods.
The buoy is part of the UK Met Office's network of Marine Automatic Weather Stations. Known as K5, it sits in the North Atlantic off the Western Isles
The buoys complement ship-based measurements and satellite observations, which monitor the oceans and forecast meteorological hazards on the high seas.
Giant waves can be created in the north Atlantic, which stretches from the Grand Banks plateau off the coast of Canada to the area south of Iceland and west of the UK.
In winter, wind circulation and pressure systems cause extratropical storms, sometimes known as bombs, the WMO said.
The height of a wave is measured from the crest of one to the trough of the next.


The UK's security and intelligence agencies are examining a video by so-called Islamic State, to identify a man and young boy with British accents.

The video purportedly shows the killing of five men who IS says were spying for the UK.
The authorities will also be carrying out voice-print analysis to match what is heard against individuals known to have travelled to Iraq and Syria.
The man threatens attacks in the UK, during the 10-minute film.
He also says the footage, which has not been independently verified, is a message for Prime Minister David Cameron.
After the apparent killings the young boy, who seems to be aged about six or seven years old and is wearing military-style clothing, is seen pointing into the distance and talking about killing "unbelievers".
In the video, the masked man who has a British accent and is holding a gun, mocks Mr Cameron for daring to "challenge the might" of the extremist group.
He goes on to say: "We will continue to wage jihad, break borders and one day invade your land where we will rule by the Sharia."
The five men, wearing jumpsuits and kneeling in a desert location, then appear to be shot in the back of the head, after making what is claimed to be their confessions.
One of the men says he had been asked to provide information about the location of IS militants, including two Britons, apparently to help target them with air strikes.
Some of the five say they are from Raqqa in Syria while another says he is from Benghazi, Libya, but none say they are from the UK.
A UK Foreign Office spokesman said: "We are aware of the video and are examining its content."
IS, also referred to as Daesh, has previously released videos showing killings, including footage showing the apparent beheading of two US journalists, James Foley and Steven Sotloff, and two British aid workers David Haines and Alan Henning.
Mohammed Emwazi, the Briton who became known as Jihadi John, appeared in the videos. He was killed in a drone strike in Syria in November.
BBC security correspondent Frank Gardner says it would "probably be a fairly short-lived attempt... to take on the mantle of Mohammed Emwazi".
He says the UK government is unlikely to say who they think he is or confirm whether the men killed in the footage were working for Britain.
"IS is absolutely paranoid about [informants]," our correspondent says.
"They are looking over their shoulders, wondering where the next drone strike is coming from and they are wondering who in their midst is informing and reporting on them."
By Gordon Corera, BBC security correspondent
It is less than two months since British IS propagandist Mohammed Emwazi, the man known as Jihadi John, was killed by a drone strike in Syria.
This latest video by IS seems to show another man trying to take up his mantle.
The identity of the masked man is so far unknown but authorities will be trying to identify him and confirm if he is British.
Emwazi was killed after intelligence - most likely from informers - located him in a vehicle in Raqqa, Syria.
The fact that this latest video shows the killing of alleged spies indicates the extent to which IS is trying to track down those who might be providing information.
Children also regularly feature in IS propaganda videos and the brief appearance of a child - apparently with a British accent - at the end of the video will also most likely be of interest to the authorities.
Abu al-Furat, a member of a Raqqa-based group which opposes IS, told BBC Radio 4's Today programme they doubted the killed men were spying for Britain.
"Daesh [IS] has been harmed very much after the death of some British citizens who are fighting with Daesh," he said.
"And in this video, the executor is trying to copy John [Emwazi]. They want to say that if John died, there are others that can do this job."
Margaret Gilmore, senior associate fellow at security think tank the Royal United Services Institute, told BBC Radio 5 live the video had "an air of desperation".
"They are trying to detract from recent setbacks," she said, highlighting recent losses in Iraq.
But Shiraz Maher, senior research fellow at the International Centre for the Study of Radicalisation at Kings College London, told Today the group remained "very powerful".
Jonathan Russell, head of policy at the counter-extremist think tank, the Quilliam Foundation, said it was "shocking" to hear British voices and to see a child in the video, but that both were being used "to reinforce the IS brand".
The IS group, notorious for its brutality, seized large swathes of territory in Syria and Iraq in 2014, when it formally declared the establishment of a "caliphate" - a state governed in accordance with Islamic law, or Sharia, by God's deputy on Earth, or caliph.


Two tourists have had more than £1,000 stolen from them in Edinburgh after being distracted by a fake police officer.

The man and woman, who were visiting from east Asia, were approached by two men at about 13:30 on Saturday outside the Scottish Parliament.
One of the men claimed to be a police officer. He showed them identification and checked their belongings.
The pair later discovered a "four-figure sum" of money had been stolen.
The theft is not thought to be linked to other recent incidents in Scotland involving fake police officers.
Police said the first suspect was east Asian, with a slim to medium build and 5ft 7ins tall. He was 30-35 years old, with short black hair and unshaven.
He was wearing a brown jacket and carrying a black backpack.
The second man is described as white, of medium build, 6ft tall, about 50 years old, with a deep scar on his right cheek.
He spoke with an English accent and was wearing a black beanie hat and a full-length black coat.
Insp David Robertson appealed for witnesses to come forward and said the theft was currently being treated as an "isolated incident".
He added: "Our officers will always be in possession of photographic identification and will be able to provide you with a unique identification number.
"If you are still unsure, please call us on 101 as the call handler can check their credentials for you and officers will be happy to wait until this has been done."


Leeds head coach Garry Monk has striker Chris Wood and defender Luke Ayling available again, but Kalvin Phillips starts a two-match ban.

Wood missed the 1-1 draw at Fulham with a calf injury, while Ayling was absent for the birth of his daughter.
QPR forward Jamie Mackie and defender Joel Lynch are available, after being rested for Tuesday's win over Barnsley.
Winger Kazenga LuaLua will not play because of an ankle problem, and Jordan Cousins (thigh) has also been out.


A 92-year-old man has a shattered ankle and a broken leg after falling down a lift shaft at a care home.

Len Condra had to undergo an emergency seven-hour operation after falling 14ft (4m) at the Haslington Care Home in Greenhithe, Kent.
His family fear the former soldier may never walk again.
The Care Quality Commission said it was investigating the incident. The care home declined to comment and referred the BBC to Kent Police.
Mr Condra has been in King's College Hospital, south-east London, since the fall at 07:40 GMT last Friday.
He had mild dementia, but his granddaughter fears that may have worsened.
Katalina Chu said: "He doesn't know where he is, doesn't know anything that's happened, he doesn't even remember me, and I'm the closest person to him.
"It shouldn't have happened, not in a care home, not a dementia ward where they need 24-hour care."
Nadra Ahmed, of the National Care Home Association, said the incident highlighted the fact the sector has "a massive recruitment and retention issue".
"There are very clear guidelines that you must have enough staff to look after the people that are within the service, and that is a judgement for the management of that care home to have made," she said.


Police took five hours to arrive at the Edinburgh home of a "seriously ill" 72-year-old man after a call of concern about his welfare, a review has found.

A report by the Police Investigations and Review Commissioner (PIRC) said officers were sent within 35 minutes on 19 April 2016, but were then diverted.
The commissioner said the delay was caused by a lack of ownership of the initial call within Police Scotland.
The report said the man was expected to make a full recovery.
The incident happened when a City of Edinburgh Council neighbourhood support officer phoned Police Scotland with concerns about the 72-year-old who has regular welfare visits but had not been seen for a few days.
There had also been no reply at his home.
The PIRC report found while the initial call to police was correctly prioritised as a Grade 2 incident, which requires a response within 15 minutes, officers were not sent for 35 minutes.
On the way to the call, those officers were diverted to another incident and it was not until some time later that it was realised that no-one had attended and other officers were then dispatched.
When those officers arrived at the property later in the day, they found the man was seriously ill and he was taken to hospital for treatment.
The commissioner, Kate Frame, said: "Fortunately in this case, the medical opinion suggests that the delay in the police attending is unlikely to have had a significant impact on the seriousness of the man's illness.
"Police Scotland has since carried out a review of the circumstances and put new safeguards in place for dealing with this type of incident, which requires supervisors to more closely monitor the actions of staff."


Islamic State militants in Libya say they have seized the airport in the city of Sirte, as the group continues to make advances in the country.

The news was announced by the group and by a Libyan militia that withdrew from the coastal city's airport on Thursday.
Most of Sirte, former leader Muammar Gaddafi's hometown, fell to IS last week.
In a statement, the group said it had also seized the Great Man Made River water project.
The irrigation project, the world's largest, supplies fresh water to Libyan cities and was also the base for the opposition Battalion 166, which has now fled.
The battalion, and other Islamist militias, run the capital, Tripoli, although their government is not recognised by the international community.
The al-Ghardabiya airport also housed an airbase, that was seized by militias after being bombed by Nato forces during the battle to oust Gaddafi in 2011.
Libya's rival power bases
The battle for Sirte: an exclusive BBC report
Since the former leader's death in Sirte in October that year, Libya has descended into chaos, with various militias fighting for power. The internationally-recognised government has been forced to leave Tripoli.
In the last seven months, IS has set up checkpoints and established a presence in cities across Libya, starting with the port of Derna - the first city outside Iraq and Syria to fall to the militant group.
In January, an IS-affiliated group bombed the Corinthia Hotel in Tripoli, killing 10 people.
In February and April, videos were released showing IS militants in Libya killing two groups of mainly Egyptian and Ethiopian Christians.
Air strikes against IS positions have been conducted by the Egyptian air force and by Libya's internationally-recognised government.


A man has been jailed for killing a 17-year-old woman by not helping her when she fell into the sea.

Becky Morgan fell in the water at the Port of Ramsgate on 1 May after a party. Michael Bowditch went clubbing after watching her die.
Bowditch, 21,  had denied murder but admitted manslaughter by gross negligence.
He was given a five-and-a-half-year prison sentence at Maidstone Crown Court.
Bowditch, of Prestedge Avenue, Ramsgate, and Miss Morgan had met at a birthday party before going to the harbour arm in Ramsgate, the court heard.
More news from Kent
Simon Taylor for the prosecution told the hearing: "Mr Bowditch accepts that although he cannot say exactly how Becky Morgan came to fall into the sea, once she fell in he failed to take any steps to try to assist her.
"It is the failure to take any steps to prevent Miss Morgan's death after she fell into the sea which forms the basis of his culpability for manslaughter."
Sentencing Bowditch, Judge Jeremy Carey said: "You did not try in any way to help a drowning girl - not by throwing her a life buoy, not by going to her aid as some would have done, not by calling for help, not by contacting the rescue or emergency services.
"In other words, you left her to drown."
Bowditch had been due to stand trial this week after denying murdering the college student, but an admission of manslaughter was accepted by Judge Carey.
The court heard when the pair went to the harbour, Bowditch was drunk and had taken cocaine and cannabis. Miss Morgan was not drunk, toxicology reports showed.
Bowditch told police they had been "mucking about" and he believed she ended up in the water sometime between 02:05 and 02:40 BST.
The court heard Miss Morgan had asked for help and told Bowditch she could not swim. He said he was unable to help.
The prosecution lawyer said: "He did not just walk away and leave Miss Morgan to perish but remained and watched her drown."
Bowditch was seen dancing in a bar at around 02:50, more than two hours before he called police.
A Kent Police spokesman said: "He appeared very drunk and was trying to chat up girls. He was thrown out by door staff 20 minutes later."
When Bowditch returned home he called police at 05:01 and said: "I've seen someone die tonight."
Miss Morgan's body was recovered from the sea at Broadstairs just after 07:45, Kent Police said.
In a statement to the court, her mother Lee-Ann Bevan said: "She was smart, mature, independent and funny. I feel like something bright has died in my life.
"I'll spend my whole life not knowing what happened," she said.
"All I can think about is her being alone in the dark and cold and frightened.
"I can only think she would have been asking for me," Ms Bevan said.


Amazon, Microsoft and Expedia have backed a legal challenge to President Donald Trump's immigration curbs.

The lawsuit, filed by Washington Attorney General Bob Ferguson, aims to prove that President Trump's order, which temporarily bars nationals from seven Muslim-majority countries from entering the US, is unconstitutional.
Amazon's Jeff Bezos said his firm had "prepared a declaration of support".
Microsoft said it would be happy to testify "if needed".
In an email to employees, Mr Bezos said: "We're a nation of immigrants whose diverse backgrounds, ideas and points of view have helped us build and invent as a nation for over 240 years. No nation is better at harnessing the energies and talents of immigrants. It's a distinctive competitive advantage for our country - one we should not weaken."
Mr Bezos said that the firm has also reached out to congressional leaders to explore legislative options.
It is the latest protest in a chorus of disapproval from Silicon Valley over the controversial executive order signed by President Trump.
Many firms have expressed concern about the order's effect on employees, with some saying it violates company principles.
Apple and Twitter have criticised it, while Netflix's chief executive Reed Hasting declared it "unAmerican."
AirBnB co-founder Brian Chesky offered free housing to anyone caught outside the US, unable to return home, while Google revealed that more than 100 staff members were directly affected.
In a statement Google said: "We're concerned about the impact of this order and any proposals that could impose restrictions on Googlers and their families, or that could create barriers to bringing great talent to the US.
"We'll continue to make our views on these issues known to leaders in Washington and elsewhere."
The White House has defended the new rules, saying that the majority of Americans agree with the president.
"They recognise that the steps that he's taken were to keep this country safe and to make sure that we didn't look back and say, 'I wish we had done the following,'" said spokesman Sean Spicer.


Francesco Gudolin says taking over at Swansea City is the "most important challenge" in his managerial career.

Media playback is not supported on this device
Guidolin, who has previously managed Udinese and Monaco, was appointed Swansea's head coach in January.
Swansea are 15th in the Premier League but have won back-to-back games since the Italian's arrival to move four points clear of the relegation zone.
"It's an important challenge because this is the most important league in the world," he said.
"In Italy I have had many experiences but this is a different league and a good challenge.
"The Premier League was a dream for me."
The 60-year-old managed several clubs in Italy from 1988 to 2014, including Palermo and Parma as well as two spells with Udinese.
Udinese finished third in Serie A under Guidolin in 2012, equalling the club's best season in the Italian top-flight.
He also achieved promotions with Parma, Palermo and Vicenza, and led the latter to an unlikely victory in the Coppa Italia in 1997.
Guidolin does not think his side will have an advantage when they face West Bromwich Albion in the Premier League on Tuesday, despite not playing at the weekend.
West Brom were held to a 2-2 draw by Peterborough United in the FA Cup fourth round on Saturday, but the Swans exited the cup in the previous round.
"We've had more days to prepare but there's no difference," Guidolin said.
West Brom's Welsh manager Tony Pulis made four changes for his side's FA Cup tie.
Pulis' side are seven points above the drop zone and defeat at the Liberty Stadium could drag the Baggies into a relegation scrap.
Swansea are one place and three points behind 14th-placed West Brom and four points clear of the bottom three.
"I'm very happy at the moment," Guidolin added. "The table wasn't good but with two victories the table is better.
"Now we have another difficult match against a good team. If we win, it will be very important but it will be difficult."
