Greek
police fired teargas to push back hundreds of stone-throwing migrants trying to cross the border from
Turkey on Saturday, as a crisis over
Syria shifted onto the European Union's doorstep.
Greece, which has tense relations with Turkey, accused Ankara of sending the migrants to the border post in an organized "onslaught" and said it would keep them out.
Turkey said on Thursday it would stop keeping hundreds of thousands of asylum seekers in its territory after an air strike on Idlib in neighboring Syria killed 33
Turkish soldiers.
