Greece Grapples With New Migration Crisis Anthee Carassava ATHENS - Authorities in Greece are facing the biggest mass migration push in years and the government in Athens is laying blame with Turkey. Greece is beefing up its defenses along its land and sea borders with its neighbor; but, the heightened controls are starting to take a deadly toll. On Monday, Greek government spokesman Stelios Petsas openly accused Turkey of engineering an organized invasion after Ankara opened its border to allow migrants to pass through to the West. Petsas said Greece is being targeted with an illegal attempt to violate its borders and will repel any such efforts. Authorities have already beefed up border controls and repeatedly tear-gassed asylum-seekers trying to enter Greece. .
