A Russian unmanned reconnaissance aircraft crashed on Sunday evening as a result of a technical malfunction in the Jabal al-Zawiya area, while rebels thwarted an incursion attempt by regime forces into southern edges of Idlib province.
A rebel source in the Al-Fateh Operations Room told Zaman al-Wasl that a Russian Orlan-10 unmanned reconnaissance aircraft crashed on Sunday evening near the town of Mantef in the Jabal al-Zawiya region.
Rebels picked up the wreckage of the plane.
Also in Jabal al-Zawiya region, rebels have thwarted the regime attack near al-Ruwaiha front, the southeastern gate of Jabal al-Zawiya. Several regime forces were wounded in rebel artillery shells.
Since the ceasefire deal, the Russian-backed regime has stopped short of launching a fully-fledged land offensive to deliver on its promise to reconquer the entire country.
But violations of the ceasefire are relatively frequent as regime forces try to maintain their stranglehold on the enclave.
Northwestern Syria is home to 3.5 million refugees but is controlled by opposition Islamist fighters.
The Syrian conflict has claimed 494,438 lives and has displaced 13,2 million people since it erupted in March 2011 with the brutal repression of anti-regime protests.
