Oct. 13 (UPI) -- Turkish forces on Friday began crossing into Syria's Idlib province in order to monitor de-escalation zones, the Turkish military said.
The troop movement is part of a joint mission between Turkey, Russia and Iran to observe de-escalation zones and remove a stronghold of former al-Qaida militants from the area. The three countries agreed in May to be guarantors of a cease-fire to help end the six-year civil war in Syria.
