A Greek coast guard vessel arrives at the port of Mytilene, after a rescue operation of refugees and migrants near the northeastern Greek island of Lesbos, Saturday, Feb. 27, 2016. Border restrictions further north in the Balkans have left thousands of refugees and other migrants stranded in a country that is still wracked by its own financial crisis and unable to seal its lengthy sea border with Turkey.
