Turkey's President Recep Tayyip Erdogan has demanded more support from his NATO and European Union allies over the war in Syria as fighting rages in Idlib, and a refugee crisis unfolds at the Turkish-Greek border. Erdogan flew to Brussels for talks with EU and NATO leaders after tensions rose over the fate of tens of thousands of refugees trying to enter EU-member Greece since Ankara said last month it would no longer try to keep them on its soil.
