Thousands of migrants had gathered Saturday in the border post of Kastanies, where some 500 Greek and soldiers police officers promptly fired tear gas to stop them from entering the EU from Turkey.
Turkey declared on Friday it might leave its boundaries with the European Union available to migrants. Ever since that time, Greek soldiers and police have stepped up their patrols across the Evros River, loudly warning of their entrance ban.
However, the place is big and hard to observe. Greek governments use drones to attempt and find groups of migrants walking close to the imperceptible line and track their progress.
In the border post of Kastanies, some 4,000 migrants and refugees accumulated behind the fences, as found by a Greek authorities supply, against 1,200 the afternoon before.
Some have increased trees, many others have busted concrete that they throw on the other side others still release tear gas canisters within the barbed wire.
