A Turkey-backed militant alliance has begun withdrawing heavy weapons from a planned demilitarized zone in the flashpoint northwestern Syrian province of Idlib. A spokesman for the alliance, known as the National Liberation Front, confirmed the weapons withdrawal. He said the coalition intends to maintain its positions in Idlib with medium and light weapons. Failaq al-Sham, another group making up the alliance, has also begun the withdrawal of arms, including missile and mortar launchers. Last month, Russia and Turkey clinched a deal on creating a demilitarized zone around Syria’s Idlib. Under the agreement, all factions in the planned zone must hand over their heavy weaponry by October tenth. The Nusra Front terror group which has to leave the zone entirely has yet to announce its stance. Idlib is the last stronghold of terror groups fighting Syrian government forces.
