100,000 refugees have entered Greece since the beginning of the year compared to 5,000 a year ago.

Where can they go? On February 16, Austria announced it will take at most 80 a day. Just this week Macedonia reduced the number of refugees allowed to transit through its territory to about 1,000 a day.

At least 15,000 are trapped in Greece, a country without resources to deal with them. In response to the growing crisis, Greece Withdraws Ambassador to Austria.

Athens withdrew its ambassador to Austria on Thursday in a sign of the mounting acrimony between EU countries over the bloc's failed refugee policies, a fight that increasingly risks destroying the continent's passport-free travel zone.
