Europe Locks Down Greece Border, Blames Turkey For Migrant Crisis Henry Ridgwell LONDON - The European Union has pledged over $780 million to help Greece cope with a surge in the number of migrants trying to cross into the country from Turkey, as the bloc fears a repeat of the 2015 refugee crisis. Greece has closed down the land border and ramped up security around islands in the Aegean Sea close to Turkey. Athens and the EU say Ankara is fully to blame for the crisis, as tens of thousands of migrants remain camped out along the border. Turkish authorities released video Tuesday appearing to show Greek security forces firing into the water close to a migrant boat off Lesbos Island. Meanwhile, Greece released its own video purporting to show a Turkish government patrol boat apparently helping a dinghy full of migrants cross towards Lesbos island. Greece is deploying soldiers and military hardware along the frontier. Athens received a show of solidarity Tuesday as the presidents of the European Union Commission, Council and Parliament joined the Greek prime minister on a visit to the land border. .
