Greek police fired tear gas to repel hundreds of stone-throwing migrants who sought to force their way across the border from Turkey on Sunday, witnesses said, with thousands more behind them after Ankara relaxed curbs on their movement.It was the second straight day of clashes at the border crossing by the northeastern Greek town of Kastanies in which police drove back approaching migrants with volleys of tear gas.
Greece had placed its borders on maximum-security footing earlier on Sunday after hundreds of other migrants used porous crossing points to enter the country.
At least 500 people had arrived by sea on the Greek islands of Lesbos, Chios and Samos close to the Turkish coast within a few hours on Sunday morning, police said.
