EU foreign ministers are set to hold an emergency meeting next week to discuss the worsening Syria situation that is driving thousands of refugees to the borders between Turkey and Greece. EU High Representative for Foreign Affairs Josep Borrell warned in a statement on Sunday from the worsening conflict. "The ongoing renewed fighting in and around Idlib represents a serious threat to international peace and security. It is causing an untold human suffering among the population, and having a grave impact on the region and beyond," he said. "I am therefore calling for an extraordinary meeting of the Foreign Affairs Council next week to discuss the unfolding situation, in particular at the request of the Minister of Foreign Affairs of Greece," Borrell added. Greek police fired tear gas to repel hundreds of 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, according to Reuters. 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. “The present situation is an active, serious, severe and asymmetrical threat to the national security of the country,” Greek government spokesman Stelios Petsas told reporters, “These ... people are being used by Turkey as pawns to exert diplomatic pressure,” he stressed. Turkey said on Thursday it would let migrants cross its borders into Europe, despite a commitment to hold them in its territory under a 2016 deal with the European Union.
