A Hungarian journalist reports that peace has returned to Bicske, where there was a stand-off between Hungarian police and hundreds of migrants, who refused to leave a train.
The Greek island of Kos is a key destination for migrants leaving by boat from Turkey. The BBC's Chris Buckler, reporting from there, says the island is lined with tents as the migrants seek shelter during the day and warmth at night.
About 2m Syrians have escaped to Turkey. The BBC's Ian Pannell says many are in camps, some are in towns and cities around Turkey. He says they may have found safety but they have no sense of a future as they cannot find jobs and making ends meet is very tough. Europe looks like the promised land.
Starting now - the BBC has a special half-hour report on the EU migrant crisis, tracking the movements of those desperate to reach Europe. Tune into BBC One or the BBC News Channel or watch online .
The BBC's Matthew Price is with migrants attempting to walk from Hungary to Austria.
The chief executive of the UK-based Refugee Council has welcomed Prime Minister David Cameron's move to "accept significant numbers of Syrian refugees".
"It's been a long time coming but we welcome it," Maurice Wren said.
"We're calling on the prime minister to be bold. Now is not the time for tokenistic measures, given the evident support there is in the country for something bold and courageous."
A Turkish court has remanded four Syrians in custody who are charged over the death of three-year-old Alan Kurdi, Reuters reports police as saying.
The picture of his body washed up on a Turkish beach prompted an international outcry.
His mother and brother also died when the boat they were in capsized. They were buried in Kobane, Syria, earlier.
After UK Prime Minister David Cameron announced the UK would be taking "thousands" of Syrians from camps along the country's border, the UN's refugee agency, the UNHCR, has issued a statement clarifying that most Syrian refugees are not living in camps. It said there are no camps in Lebanon, which is hosting at least 1 million Syrians, and in Turkey only around 15% live in camps. The majority live in very difficult urban settings such as disused buildings.
The BBC's Imogen Foulkes says the UNHCR may want Britain in particular to understand that the real picture of the Syrian refugee crisis is rather different, and often a good deal worse, than the typical image we might have of a refugee camp.
EU Chief Executive Jean-Claude Juncker is preparing to defy European national leaders by making a new bid to force them to take in quotas of asylum-seekers, Reuters reports officials as saying.
He will announce an "enhanced proposal for relocation next week, especially for the three most affected countries, Greece, Italy and Hungary," his deputy, Vice President Frans Timmermans says.
He said the Commission would insist the people who arrive in Europe are spread around the member states.
Germany and France back quotas, but Hungary, the Czech Republic, Poland and Slovakia rejected them earlier.

US Presidential hopeful Hillary Clinton has said in an interview with MSNBC that her country should do its part to work with international groups to help refugees, Reuters reports.
"The entire world should come together. It should not be just one or two countries, or not just Europe and the United States," the Democratic party front-runner said.
"We should do our part, as should the Europeans, but this is a broader global crisis."
Migrants at Roszke camp in Hungary have broken through barriers and clashed with riot police, the Reuters news agency has quoted witnesses as saying.
German customs officers have seized packages containing Syrian passports, according to Germany's MDR broadcaster. It reports that both genuine and false passports were found, and police are investigating a suspected black market trade. The passports are much prized by refugees hoping to get asylum in Germany, the report says.

A Pakistani man has died in Hungary after collapsing on railway tracks when a group of about 350 migrants escaped from a train station where 800 migrants were being held by authorities, Reuters reports.
Police said they did not chase the group and the man collapsed about 800m from the station in Bicske, west of Budapest.
State television said the man fell and hit his head on the tracks.
Bicske has been the scene of a stand-off between police and migrants, who refused to go to a transit camp to be processed.

The BBC's Matthew Price is walking with hundreds of people who left Keleti station in Hungary's capital Budapest, intent on walking to Austria after they were stopped from boarding westbound trains.
He says the group includes a man with a child and another pushing a wheelchair.
One migrant tells him: "We will keep going until we get to Austria, and then Germany. Angela Merkel is our mum."

Key points from the emergency meeting of Poland, Czech Republic, Slovakia and Hungary:
- Czech Prime Minister Bohuslav Sobotka says Europe is "witnessing chaos"
- He says the leaders agreed on the need to protect borders and fight trafficking
- A German plan for a binding quota system for relocating migrants was opposed
- However, the Czech Republic and Slovakia say they could accept a railway corridor for Syrian refugees travelling from Hungary to Germany, if Berlin and Budapest agree.

The cartoon above has been getting a lot of attention on social media since it was published in several Middle Eastern newspapers.
It depicts Alan Kurdi, the three-year-old Syrian boy who died during his family's attempt to cross the Mediterranean from Turkey earlier this week.
Rafat al-Khateeb, the artist behind it, told the Independent: "The main idea [behind the cartoon] is that a child does not know about war and crime.
"The child knows one thing only.That the whole world is responsible for his death."
The image is one of several cartoons that have caught the attention of people on social media this week - but not all of them are new. This one below is from 2014 but has been shared hundreds of time in recent days.
The first migrants are being brought off the train at Bicske now. They are moving quietly to a waiting bus. No resistance from this group.
In a joint statement, the prime ministers of the Czech Republic, Hungary, Poland and Slovakia reject any quota system for accepting migrants.
They insisted "any proposal leading to introduction of mandatory and permanent quota for solidarity measures would be unacceptable''.

BBC News producer Ron Brown says following the clash between right wing extremists and refugees waiting outside Keleti station just now, calm has been restored and people are sitting down in protest.
They want to take trains on to Austria and Germany but are not being allowed to.
Following earlier reports of as many as 50 people dying in a dinghy off Libya, the International Organization for Migration confirms the number is between 30 and 40.
The dinghy was carrying up to 140 Somali, Sudanese and Nigerian migrants when it deflated about seven hours after leaving Misrata.

The BBC's Ben Brown at Keleti train station in Budapest reports: "In the last few minutes Hungarian right-wing extremists have thrown fire crackers into what is a makeshift refugee camp at this station. There were two loud explosions.
"A lot of refugees were understandably frightened and some of the men then chased the far-right extremists, who were skinheads.
"There were clashes and plastic bottles that were thrown. Riot police were called in."
Our correspondent adds the group had clearly come to "goad and antagonise" the refugees.
Earlier, there were reports that riot police were preparing to move in on migrants camped out in a stationary train at Bicske station in Hungary.
Now it seems a large crowd of those migrants have chosen to pre-empt the police operation and flee, with the journalist below posting footage that shows dozens marching down train tracks.

Spanish Prime Minister Mariano Rajoy says European nations cannot refuse to grant asylum to those who have a right to it under international law.
"We need to welcome people, we need to protect people who are persecuted in their countries and we believe that this is a moral duty of every single person in Europe. So Spain is going to have a policy, as it has always had, that is constructive and positive.
"All those people who ask for asylum and have a right to asylum are going to be heard and we are going to do this along with the other countries in the European Union to resolve this problem."

UK Secretary of State for International Development Justine Greening has said the country has provided as much help to Syrian refugees in the Middle East region as the rest of the EU put together.
She adds: "We are the biggest bi-lateral donor after the US. Overwhelmingly they [refugees] want to be able to rebuild their lives there and that's why we've focused our efforts on helping them do that."
On the UK's pledge to accept thousands more Syrian refugees, she says it's "much smarter and safer" to help people directly relocate from refugee camps in the Middle East.

David Cameron says that "as a father and as a human being you can't help but be moved by the terrible pictures. Seeing the picture of that poor child on the beach in Turkey - those images will remain with all of us for a very, very long time.
"But the question you have to ask, not just as a father, but as a prime minister, is what are the actions we can take that will really make a difference.
"I think it's so important that we take [people] from Syrian refugee camps.
"I want to send the message out that the best way to get a new life is not to make this perilous journey, not to set out from the Turkish coast or another coast or trail across continents and put your lives and your family's lives at risk."

More photographs have been sent to the BBC from inside the train at Bicske. It contains migrants who want to leave Hungary, but the authorities want them to disembark and go to camps which have been set up.
The images show the extent of the overcrowding inside the carriages, with one passenger saying there is "no food, no water, nothing inside".

The aunt of Alan Kurdi, the Syrian boy who drowned on a Turkish beach, says she regrets giving his family the money they paid to people traffickers, the London Evening Standard reports.
Alan and his five-year-old brother drowned with their mother Rehan, 35, trying to reach Greece in a dinghy.
Tima Kurdi, who lives in Canada, said she had apologised to Alan's father for unwittingly playing a part in the tragedy.
Find out more about Alan's family here.
Nick Thorpe, the BBC's correspondent at the station in Bicske, says police appear to be gathering around the train.
A little earlier, Hungary's parliament passed a series of new laws as part of a crackdown on illegal immigrants, meaning:
- It will be a criminal offence to cross or damage the fence being constructed along the border with Serbia
- Illegal border crossing will be punishable by up to three years in prison
- It will be possible to submit asylum requests at border crossing points
Earlier, Prime Minister Viktor Orban told public radio: "Now we talk about hundreds of thousands [of migrants] but next year we will talk about millions and there is no end to this.
"All of a sudden we will see that we are in a minority in our own continent."
Meanwhile, about 2,300 migrants at a reception camp in southern Hungary have threatened to follow 300 who have already broken out.
Singer Bob Geldof is the latest celebrity to offer a home to refugees. He told Ireland's RTE radio station he would house four Syrian families at his two homes in Britain. He called the crisis a "sickening disgrace".
Hundreds of migrants are still camped out at Budapest's Keleti railway station in the hope of getting on trains to other parts of Europe.
Hungarian police reopened the station to migrants on Thursday after shutting it off for two days - but all trains to western Europe have been cancelled.
You can see what conditions at the makeshift camp are like in the video tour below by the BBC's Matthew Price.

Several migrants were injured by a fire that gutted a migrants' hostel last night in Heppenheim, near the city of Frankfurt in western Germany.
One was seriously hurt when he jumped out of a window. The others suffered from smoke inhalation.
It is not yet clear whether it was arson or an accident, but police have opened an investigation into the incident.
It is the latest in a spate of fires at migrant hostels in Germany.

Viktor Orban's approach to the migrant crisis has drawn strong criticism from EU politicians. But the Hungarian prime minister has long riled many of his European colleagues with divisive domestic and foreign policies, which have seen him boost ties with Russia.

People holding out on the train at Bicske have told police that women and children in their group will leave for Germany on foot on Saturday if their train is not allowed to continue its journey, according to the Reuters news agency.
There are also reports that more than 60 migrants who were taken to a nearby refugee camp have left the site.
BBC News, Hungary
Food and water is being rejected by people on the train in Bicske. Occasionally a bottle of water is handed over the heads of people to children.
Their position remains firm. They refuse to budge.
People are complaining that there's not enough information.
The Belgian government is looking for extra accommodation to house migrants who have filed official asylum applications, according to the Flandersnews.be website.
"As the Immigration Office can't cope with the influx of refugees, many of them had to wait extra days and were forced to seek shelter in a tent in a nearby park, but this should change now through a type of 'pre-accommodation'," a statement says.
Nigel Farage, leader of the UK Independence Party, has said that most of those crossing the Mediterranean are economic migrants, and should not be encouraged to make the journey.
"The EU has got this wrong. Anybody that comes, from whatever background and virtually for whatever reason, can claim to be a refugee.
"If the European Union wants to help genuine refugees, they need to establish offshore centres and process people correctly, rather than inviting what has now turned into a headlong rush."

The call by Hungary's foreign minister for migrants to leave the Keleti train station in Budapest appears to have been heeded by some - although they say they're walking to Austria rather than camps inside Hungary.

Nicola Sturgeon says Scotland should accept 1,000 people fleeing Syria as a "starting point" for further help.
Speaking at a summit in Edinburgh to discuss the crisis, the First Minister also criticised the UK Government, accusing it of "struggling to show leadership in this refugee crisis".
And she described the situation, sparked by hundreds of thousands fleeing from Syria to Europe, as the worst humanitarian disaster since World War Two.

Hungarian Foreign Minister Peter Szijjarto has called on migrants camped at the Keleti train station in the capital, Budapest, to leave the area.
He said the station "is not a refugee station. They have to leave the railway station, they have to leave the public area. It's so simple".
Authorities were ensuring that those migrants who had gone to refugee camps in the country had all the "necessary supplies," he added.
Several hundred people have been camped at the Keleti train station since Hungarian authorities cancelled trains to other European countries.
The Council of Europe Commissioner for Human Rights, Nils Muiznieks, has called the Hungarian government's stance on refugees "deeply regrettable".
"Hungary, as all European countries, has an obligation to provide protection to those who need it, regardless of their religion or any other personal trait.
"Moreover, the recent set of legislative amendments aimed at restricting immigration, including the creation of a transit zone at the border and the criminalisation of irregular border crossing, are a bad move which would have further deleterious effects on asylum seekers."

European Commission vice-president Frans Timmermans has been speaking at a press conference on Kos, one of several Greek islands where thousands of people arrive from Turkey.
He said that if the EU fails to help migrants, Europe will be left to "the xenophobes, the extremists, who will destroy it".
He added: "We are facing a moment of truth in European history. We can succeed jointly and united, or we can fail each in our own way, in our own country, on our own islands."
Italian Prime Minister Matteo Renzi has said Europe must show its "human face" in dealing with the migrant crisis, according to the Times of Malta.
"There is no alternative but to save the lives of those trying to cross the Mediterranean," he told reporters in Florence,.
Speaking at a joint news conference with Malta's Prime Minister Joseph Muscat, Mr Renzi added that the issue was no longer limited to the Mediterranean region but had spread throughout Europe, meaning a "European solution" is needed.

This picture has been sent to a BBC News producer by a man on the train at Bicske in Hungary, after he shouted out his phone number across the tracks. Those on board are involved in a stand-off with authorities after refusing to disembark.
Authorities want to move them to a nearby refugee camp - but the migrants fear registering there will hamper their plans to seek asylum in Germany and other countries.
More on that news of another boat carrying migrants sinking off the coast of Libya.
The IOM spokesman said some of those on board the vessel were rescued by the Italian navy and taken to the island of Lampedusa.
The boat is reported to have deflated shortly after it left Libya. Rescuers said they had recovered one body so far.
A spokesman for the International Organization for Migration (IOM) has told the BBC that up to 50 migrants are missing after their boat sank off the coast of Libya.
There's a slightly surreal feeling to the situation at Bicske station in Hungary today as hundreds of migrants continue to refuse to get off a stationary train.
The train left Budapest yesterday - with those on board unsure of its destination - but it came to a halt in Bicske and migrants were asked to disembark and get on buses that would take them to a nearby refugee camp.
One of those on the train told the Reuters news agency that conditions on board were "so bad".
Another person who has travelled from Syria said: "We have war in our country and we've come to get our freedom here in Europe. Where is the human rights? Where is the United Nations?"
The International Olympic Committee has announced a $2m (£1.3m, €1.8m) fund that will be made available to National Olympic Committees for "programmes focused on refugees".
IOC President Thomas Bach said: "We have all been touched by the terrible news and the heartbreaking stories in the past few days.
"With this terrible crisis unfolding across the Middle East, Africa and Europe, sport and the Olympic Movement wanted to play its part in bringing humanitarian help to the refugees."
Twitter has put together a nice interactive map showing who was tweeting using the #refugeeswelcome hashtag this week.
The hashtag appears to have been very popular in Germany, which is the preferred destination of many of the migrants.
Karl-Heinz Grundboeck, spokesman for the Austrian interior ministry, says the number of people claiming asylum in Austria is increasing.
He told the BBC that an average of 300 people a day are claiming asylum there.
From January to the end of July, 37,000 people requested asylum, and Mr Grundboeck said an estimated 8,800 people claimed asylum in August.
The country is currently expecting around 80,000 applications by the end of the year. Austria has a population of 8.5 million.

Dima Albadra is a Syrian woman living in Bath, who is applying for asylum in the UK.
"I was already studying in the UK when the revolution started in Syria. I do think the UK should accept more refugees but I agree with David Cameron that the problem of the crisis needs to be tackled at the source because refugees are a symptom of war.
"I know people in Syria who have taken the risk and made the dangerous journey to Turkey, Jordan and Libya. They want to leave Syria because of the fear of bomb attacks.
"There is no stability in Syria. There is exploitation. There is no prospect for education. People want a better life for their children They go to Turkey, Jordan and Libya but these countries do not have the infrastructure to cope. They are poor countries so that is why people move on."
There are some more pictures coming in from the funeral of three-year-old Alan Kurdi, his brother and mother in Kobane in Syria.
Speaking to Turkish news agency Dogan earlier today, Alan's father said: "As a father who lost his children, I want nothing for myself from this world."
Abdullah, shown below, added: "All I want is that this tragedy in Syria immediately ends and peace again reigns."

Speaking in Portugal, UK Prime Minister David Cameron said taking people from refugee camps provided a safer route to Europe than trying reach it by sea.
He said: "Britain will act with our head and our heart, providing refuge for those in need while working on long term solutions to this crisis.
"As I said earlier in the week, that means bringing to an end the conflicts that are driving so many to flee, including the bloodbath that has engulfed Syria."
Prime Minister David Cameron has just said that he will set out plans next week for the UK to take "thousands more" refugees from camps on the Syrian borders. You can read the full story here.
Representatives of three of Northern Ireland's five main parties have indicated that they feel that there is capacity to accommodate up to 2,000 migrants.
The DUP, Ulster Unionists and Sinn Fein are reported to broadly agree that this figure is manageable.
Ireland is to take in at least 1,800 people, Justice Minister Frances Fitzgerald has just announced.
This effectively trebles original plans announced in July to accept 600 people, mainly from Syria and Eritrea, over the next two years.
She told RTE Radio: "What we have seen is heartbreaking and tragic and I think it demands the most comprehensive response.
"I think it will be in the thousands. It's very hard to put a precise figure on it. We want to respond in as humanitarian a way as possible."

Green Party Leader Natalie Bennett has told BBC Radio 5 live that Britain should take in about a quarter of a million migrants.
"There's probably up to two million refugees who are looking to resettle. If you look at Britain's fair share of that... we're looking at potentially up to 240,000 people.
"Sounds like a very large number when you say it, but that's one refugee for every 266 Britons and a 0.4% increase in our population."

The boy who drowned on a Turkish beach has had his name spelt as Aylan by much of the media, including the BBC.
However, his aunt Teema Kurdi told the BBC on Thursday that this was a Turkish version of the name given by Turkish officials - his Kurdish name was Alan.
His body and those of his brother and mother are currently being taken to Kobane in Syria, where a funeral is expected to be held later today.
A group of Berlin-based volunteers, called Berlin Refugee Help, have launched a Refugee Phrasebook. They describe it as a "multilingual tool for refugees who just arrived in Europe that provides basic useful vocabulary and sentences related to the most common immediate needs".
It currently contains vocabulary in 28 languages.
The distressing images of Alan Kurdi's body were taken by photographer Nilufer Demir, 29.
She told Le Monde newspaper (in French) that she did not expect photos of the three-year-old Syrian boy to be so widely shared on social media and be published by newspapers around the world.
"When I arrived [at the beach] about 6 or 7 in the morning… we could make out something washed up on the beach. We could see straight away that he was dead and there was nothing we could do."
"I was really shocked to start with but I pulled myself together very quickly. I told myself that I could bear witness to the plight of these people. I had to take this photo and I didn't hesitate to… I was sad because it was the body of a child - but it could also have been the body of an adult and I have photographed that many times already."
The AFP news agency reports that Abdullah Kurdi has returned to the town of Kobane in Syria, to bury the bodies of his wife and sons who drowned while attempting to reach Europe.
Images of three-year-old Alan, whose body was washed up on a Turkish beach on Wednesday, sparked an international outcry over the migrant crisis.
You can read the Syrian family's tragic story here.
Yasmine Nahlawi, from the Centre for Syrian Studies in the UK, has been talking to the BBC this morning about the migrant crisis.
She said the British government had a responsibility to help not just those in refugee camps, but those trying to cross the Mediterranean to western Europe.
"They are our responsibility. We cannot turn our face away from their plight. And we will have to accept some of them."
"At the end of the day these people are victims. We're talking about people who are seeking asylum from war, from death."

The BBC's Matthew Price has been speaking to a Syrian family from Homs who have made a four-year journey to a camp in Hungary.
Hamza, an English teacher and mother-of-three, fled with her engineer husband, two daughters of 14 and 18, and 8-year-old son.
The family spent time in Damascus before moving on to Lebanon and Turkey, then travelled to Greece in a rubber dinghy, and have since journeyed through Macedonia and into Hungary.
“All the governments make this war on Syria," said Hamza. "They put their hands in everything, even in the war, and now they have prevented us from going to their countries."
Hamza says she will "try and try and try” to get her family to Germany.

Hundreds of migrants spent last night on a train at Bicske station in Hungary, about 40km (25 miles) west of the capital, Budapest.
It left Budapest's Keleti station on Thursday but stopped in Bicske, where police tried to force refugees off the train and on to buses to a nearby refugee camp.
The refugees fear that registering at the camp will make it harder for them to seek asylum in Germany and other European countries.
