Greece has blocked nearly 10,000 migrants trying to enter from the Turkey border over the past 24 hours.
A Greek government source said yesterday that its army and police had stopped thousands from entering its territory.
The source said, huge crowds tried to cross into Greece via the Kastanies Forest in the early hours today. Greek authorities said, 73 migrants had been arrested.
Greek security forces are
patrolling the Evros river shores, a common crossing point, and have issued loudspeaker warnings not to enter Greek territory.
Yesterday clashes erupted along the border, where Greek police fired tear gas at migrants who in turn lobbed rocks at officers.
Meanwhile, the EU's border protection agency Frontex said, it is on high on Europe's borders with Turkey as thousands of migrants seek to enter the bloc.
