Syrian News Agency reported that Syrian forces launched missile attacks targeting positions of al-Nusra Front terrorists and its affiliated groups in the vicinity of the town of Saraqeb in Idlib countryside.
Several terrorists were reported killed and injured during the military operation.
Under the deal reached following a meeting between Turkish President Recep Tayyip Erdogan and his Russian counterpart Vladimir Putin in September, all militants should have withdrawn from the demilitarization zone by October 15.
However, al-Qaeda-linked Takfiri terrorists said they refuse to either leave the buffer zone or hand over their weapons.
Idlib and some surrounding areas are the last major bastions of Takfiri terrorists and anti-government militants in Syria, where the Syrian government has in recent months retaken much of the territory it had lost since the conflict erupted in the country in 2011.
