Turkey says world powers must impose no-fly zone in Syria

ANKARA (Reuters) - Turkey said on Friday that world powers must impose a no-fly zone in Syria to protect hundreds of thousands of people displaced by clashes, after the killing of 33 Turkish soldiers by Syrian air strikes in the Idlib region.

Turkey will no longer stop the nearly 4 million refugees it hosts from reaching Europe, a senior Turkish official told Reuters late on Thursday, as Ankara responded to the killing of its soldiers in the northwestern region of Idlib.
