The Syrian opposition Fatah Army announced on Monday that it killed at least 12 regime troops in al Foua town in Idlib, including Iranian-backed Hezbollah militants, according to Turkey's Anadolu Agency.
Fighters belonging to the Fatah Army exchanged fire with regime soldiers and Hezbollah militias northeast of Idlib and launched short-range missiles at Foua and Kefraya where they killed the 12.
The Fatah Army includes seven opposition groups - Jund al Aqsa, Islam Army, and the Al Qaeda affiliated Nusra Front - which came together in March in order to fight against the regime and capture Idlib province, one of its main strongholds. They announced the capture of Idlib after four days of fighting with regime forces on March 28.
The civil war in Syria began in 2011 following a brutal crackdown on anti-government demonstrations and later developed into a multi sided conflict between five main factions - the Syrian regime, opposition groups, the Nusra Front, ISIS, and the Kurdish YPG militia.
According to the United Nations, the four-year-long war in Syria has left more than 250,000 people dead and 6.7 million internally displaced while at least 5.4 million have fled the country.
