Fears are growing that Europe's Schengen rules on free movement across borders is "pretty much collapsing" under the pressure from migrant arrivals as Hungary was forced to halt trains travelling westbound towards Germany today.
Hungary's Prime Minister Viktor Orban blamed the Germans and their open arms policy on accepting refugees for "encouraging migrants" to ome to Europe.

Thousands of migrants reportedly travelled for Hungary to Germany this weekend, using a key train line that runs through Austria.
Taking advantage of the Schengen agreement, which allows passport-free travel through most of Europe, the migrants were able to board trains without having to undergo identification checks.
Hungarian Prime Minister Viktor Orban is set to meet with European Union leaders in Brussels this week to discuss the current migration crisis.
Orban will consult with EU Commission President Jean-Claude Juncker, European Council Chairman Donald Tusk, European Parliament President Martin Schulz, and European People's Party chair Joseph Daul on Thursday to try to find a solution to the issue.
An extraordinary summit in Prague on Friday will also be held by leaders of Poland, the Czech Republic, Slovakia and Hungary.
The European Commission has been urged to come up with a solution to the current migrant crisis.
German Chancellor Angela Merkel and Spanish Prime Minister Mariano Rajoy said proposals needed to be drawn up to establish how Europe will cope with the current influx of refugee and migrants.
Rajoy told a press conference: "There are two things we must say clearly - the European Commission must say, identify what are the safe countries of origin ... and we need to work towards a certain harmonisation in future."
Hungary's Eastern Railway Terminus has reopened for train traffic, according to news agency MTI.
But migrants are not allowed into Budapest's station, the agency said.
The station closed for more than an hour as hundreds of migrants arrived to board trains to the west towards Austria and Germany.
A governmnet spokesperson said that Hungary is trying to adhere to European Union law after closing the railway terminus in Budapest.
Asked why the station was closed, government spokesperson Zoltan Kovacs said they were trying to enforce EU law, which requires anyone who wishes to travel within Europe to hold a valid passport and Schengen visa.
Hundreds of angry migrants demonstrated outside Budapest's shuttered Eastern Railway Terminus today, demanding that the station be reopened and they be allowed to travel on to Germany.
Over the weekend, German Chancellor Angela Merkel urged other EU countries to accept a greater share of the refugees, as her government struggles to cope with an expected record 800,000 arrivals this year.
Hundreds of migrants have gathered outside Budapest station today to protest the closure of the capital's main rail terminus.
As many as 1,000 people are reportedly waiting outside the station chanting 'Germany, Germany' and waving their tickets at police who have blocked the entrance.
The train station closure follows reports that a record number of migrants had arrived in Vienna, Austria yesterday, en route to Germany, after travelling from Hungary via train.
A second foreign suspect has been arrested in connection with last month's Bangkok bombing, Thailand's Prime Minister confirmed today.
The arrest comes two days after a 28-year-old "foreigner" was detained by police during a raid at a flat in the north of the capital.
The male suspect was arrested in Sa Kaeo province, which is east of Bangkok on the border with Cambodia, Prayuth said.
"We have arrested one more, he is not a Thai," Prayuth told reporters after a weekly cabinet meeting.
