Turkey warns Europe they may reopen the route for Syrian refugees if they do not get more 'logistical support' for creating a safe zone in northern Syria.
Turkey is hosting more than 3.6 million Syrians who fled the civil war.
President Recep Tayyip Erdogan said that they need logistical support so Turkey can build housing at 30km depth in northern Syria.
"Either, this happens, or we will be forced to open the gates," he said.
The US back the 'safe zone' plan.
