Syrian army forces on Tuesday evening shot down the drone loaded with bombs over Tal Meleh village in the western-central province of Hama, SANA reported.
The combat UAV had entered a planned buffer zone, which surrounds Idlib and also parts of the adjacent provinces of Aleppo and Hama.
Under a 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President Recep Tayyip Erdogan and his Russian counterpart Vladimir Putin in September, all militants should have withdrawn from the demilitarization zone by October 15.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.
