The Syrian army on Wednesday killed 50 rebel fighters in an ambush in the eastern countryside of the capital Damascus, according to the national Syrian TV.
The rebels were trying to move from the town of Maida'a in the eastern Ghouta countryside toward the town of Dumair, said the TV, adding that the Syrian troops eliminated 50 of the rebels in a "perfect ambush", Xinhua reported.
The Syrian army has for long been engaged in ongoing battles with the rebels in the eastern countryside of Damascus.
Separately, the Syrian troops killed tens of the al-Qaida-linked groups in the vicinity of the towns of Nubul and Zahra in the northern province of Aleppo, according to the official SANA news agency.
The extremist groups have recently unleashed a wide-scale offensive against the two towns, which are inhabited by people of the Shiite sect.
However, the towns' National Defense Forces (NDF), a pro-government militia, succeeded to fend off the attacks so far.
The Syrian crisis has been dragging on since 2011 with no sign of abating despite all of the international efforts to bring the long-running crisis to a close.
The conflict has got more complicated when ultra-radical groups, like the Islamic State (IS) and the Nusra Front, joined the fight to serve their own interests in the war-torn country, where over 190,000 people were reportedly killed and millions of others displaced during the grinding war.
