According to Al-Alam reporter, most of the killed armed militants were members of the al-Qaeda-linked al-Nusra Front group including explosive experts carrying out attacks among civilians and government forces.
At least thirteen militants of al-Nusra Front were killed in clashes, the report added.
Syria forces also killed another 28 militants including three explosive experts inside Latakia, destroying two vehicles with mounted machine guns.
Syrian army has beefed up its operations against different armed groups on the outskirts of Damascus too.
Elsewhere, after taking control of the strategic city of al-Yarobiyah, the Committees for the Protection of the Kurdish People (YPG) kicked off its third phase of military operation against the Islamic State of Iraq and the Levant (ISIS) and al-Nusra Front.
Al-Yarobiyah is a town located on the outskirts of al-Hasakah province in the far north-east corner of Syria near the Iraq border.
Capturing al-Yarobiyah overlooking Syria-Iraq international road gives Kurdish fighters upper hand in transportation and helping other Kurdish gunmen to break the siege.
