KASTANIES/LESBOS, Greece (Reuters) - Greek police fired tear gas to repel hundreds of stone-throwing migrants who tried to force their way across the border from Turkey on Sunday, with thousands more behind them after Ankara relaxed curbs on their movement.
The Greek government called the confrontations a threat to national security. "Do not attempt to enter Greece illegally - you will be turned back," Prime Minister Kyriakos Mitsotakis said on Twitter after a security meeting on the situation.
