Athens: Tensions reached boiling point between European states worst affected by the migrant crisis ahead of a meeting of Balkan states on Wednesday, as new figures showed no let-up in the influx of people.

With migrant and refugee arrivals in Europe surpassing 110,000 in the first two months of the year alone, the United Nations warned border restrictions being imposed by some states could cause chaos.

A diplomatic spat broke out between Greece and Austria, while Vienna lashed out at Germany’s ‘contradictory’ refugee policy.

The European Union voiced concerns about the risk of a ‘humanitarian crisis,’ particularly in Greece, which lies on the frontline of Europe’s greatest migration challenge since World War II.

Thousands of people have been left stranded in Greece after Macedonia abruptly closed its border to Afghans, creating a fresh bottleneck on the Balkans route to northern Europe.

Athens also hit out at Vienna for failing to invite Greek representatives to a meeting on the crisis with ministers from western Balkan states on Wednesday.

Greece’s foreign ministry blasted the meeting as ‘one-sided and not at all friendly’, and has accused Austria of undermining efforts to reach a joint European response to the crisis.

Austria retorted that it was a ‘fixed’ meeting format and its summary would be available to EU interior and justice ministers when they meet on Thursday.

Tempers flaring

Austria lashed out at Germany’s ‘contradictory’ refugee policy after Berlin sharply criticised a daily limit introduced by Vienna on migrants registering and passing through the Alpine country.

‘Germany should decide which number is acceptable to it,’ Austrian

Chancellor Werner Faymann told reporters. A statement added that he wished for a ‘respectful treatment of Austria’s political decisions’.

New figures published by the International Organization for Migration showed 102,547 people had arrived in Greece and another 7,507 in Italy so far this year.

Another 413 lost their lives trying, including 321 who perished on the journey to Greece, the IOM said.

The Mediterranean was the scene of another tragedy on Tuesday, with Italy saying it had found four bodies off the coast of Libya and rescued more than 700 migrants.

Amnesty International on Wednesday hit out at Europe’s ‘shameful’ response to the crisis, saying most EU countries had ‘simply decided that the protection of their borders is more important than the protection of the rights of refugees’.

In the latest in a series of measures by European states, Macedonia closed its border to Afghans and introduced more stringent document checks for Syrians and Iraqis seeking to travel to northern and Western Europe.

The move caused a bottleneck at the Greek-Macedonian border—where nearly 4,000 people were waiting to get through on Tuesday—and forced Greek police to keep hundreds of others from travelling to the frontier.

On the Greek side, Afghan families boarded nearly a dozen buses for the long trip back to the capital, where they will be temporarily housed in relocation camps, local police said.
