BUDAPEST, HUNGARY - SEPTEMBER 03: Migrants board trains in Keleti station after it was reopened this morning in central Budapest on September 3, 2015 in Budapest, Hungary. Although the station has reopened all international trains to Western Europe have been cancelled. According to the Hungarian authorities a record number of migrants from many parts of the Middle East, Africa and Asia are crossing the border from Serbia. Since the beginning of 2015 the number of migrants using the so-called Balkans route has exploded with migrants arriving in Greece from Turkey and then travelling on through Macedonia and Serbia before entering the EU via Hungary. The massive increase, said to be the largest migration of people since World War II, led Hungarian Prime Minister Victor Orban to order Hungary's army to build a steel and barbed wire security barrier along its entire border with Serbia, after more than 100,000 asylum seekers from a variety of countries and war zones entered the country so far this year.

Police have stood down at Budapest's main railway station after a two-day standoff with refugees, sparking chaotic scenes.

Witnesses said people rushed platforms after the station's doors were opened, but officials said no trains would be running to western Europe.

Amid the confusion and an intial pause in which the station ran no services at all, some domestic trains were allowed to leave platforms headed for towns not far from the Austrian and Slovakian borders.

But reports from Hungary suggest refugees were hauled off those trains at the first stop west of Budapest, amid a hardening of the rhetoric surrounding the crisis from the Hungarian government.

Hungary has seen a surge in numbers of refugees fleeing war-torn countries, with 107,500 arriving in July alone.

A Reuters photographer said the square outside Budapest's station, which has been full of increasingly desperate people for two days, emptied early on Thursday as more than 1,000 entered the terminal.

The main rail operator at the Keleti station said it had cancelled trains to western Europe due to "railway transport" security reasons - it did not elaborate further.

Some ended up getting off the domestic trains, according to the Associated Press, but many remained on the carriages amid the confusion.

Hungary has offered the tantalising hope of opening up the station already this week. On Monday, it allowed more than 1,000 to pack a small group of westward services, then shut them back down after 24 hours.

Expand Close BUDAPEST, HUNGARY - SEPTEMBER 03: A migrant receives medical attention as people protest against being taken to a refugee camp from a train that has been held at Bicske station on September 3, 2015 in Bicske, near Budapest, Hungary. Although the station has reopened all international trains to Western Europe have been cancelled. According to the Hungarian authorities a record number of migrants from many parts of the Middle East, Africa and Asia are crossing the border from Serbia. Since the beginning of 2015 the number of migrants using the so-called Balkans route has exploded with migrants arriving in Greece from Turkey and then travelling on through Macedonia and Serbia before entering the EU via Hungary. The massive increase, said to be the largest migration of people since World War II, led Hungarian Prime Minister Victor Orban to order Hungary's army to build a steel and barbed wire security barrier along its entire border with Serbia, after more than 100,000 asylum seekers from a variety of countries and war zones entered the country so far this year.

Hungary, which has previously moved on almost all asylum applicants to other EU countries, stopped doing so this week and said it had the backing of its neighbours to block refugees' progress.

The country was alone among EU member states earlier this year when it said it would not offer a single home to Syrian or Eritrean asylum-seekers as part of a bloc-wide commitment.

Its anti-immigrant prime minister, Viktor Orban, said after talks in Brussels today that no refugee would be allowed to pass through Hungary unchecked, and that he was pushing through measures to create "a new legal situation at the borders, even more strict that it was".

Meanwhile, Britain's government faced increasing pressure on Wednesday to do more to help Wednesday after a picture emerged from Turkey of three-year-old Aylan Kurdi, who drowned trying to reach the Greek island of Kos after his family fled Isis in Kobani.

Charities and opposition politicians are calling for change, and making their voices heard.
