The EU has told migrants in Turkey that Europe’s doors are closed as Greek and Turkish police fired teargas at their shared border amid growing tensions over the plight of Syria’s refugees. In a blunt message, the EU’s foreign policy chief, Josep Borrell, said: “Don’t go to the border. The border is not open. If someone tells you that you can go because the border is open … that is not true. Avoid the situation in which you could be in danger … Avoid moving to a closed door,” he said. “And please don’t tell people that they can go because it’s not true.” Borrell was speaking after a hastily convened meeting of EU foreign ministers in Zagreb, where the bloc restated its criticism of “Turkey’s use of migratory pressure for political purposes”. Tensions flared last weekend when the Turkish president, Recep Tayyip Erdoğan, declared he was “opening the doors” because Turkey could no longer cope with refugees fleeing Idlib province, the last remaining rebel stronghold in Syria. Thousands of refugees and migrants have since attempted to reach Greece via its land or sea borders. Greek riot police have been using teargas and water cannon to repel people trying to get into the country, while Turkish police have been firing volleys of teargas towards Greece in return.
