Syrian rebels have captured an arms and ammunition dump in Qalamun, near Damascus, according to the Syrian Observatory for Human Rights.
In the north, fighting between Kurds and jihadists raged as the main opposition National Coalition called on armed groups there to â€œexercise restraintâ€.
Several groups, including the jihadist Al-Nusra Front, were behind the capture of the depot of anti-tank weapons and rockets, according to the group.
â€œLiwa al-Islam, Al-Nusra Front, Al-Tawhid battalion, the Maghaweer (rebel commando force) and the Qalamun Martyrsâ€™ battalion … captured an ammunitions depot near the village of Qaldun in the Qalamun areaâ€ northeast of the capital, the Observatory said.
They seized â€œanti-tank weapons and ground-to-ground Grad missiles, as well as a variety of other ammunition, after clashes overnight from Friday to Saturdayâ€, it said.
In Damascus itself, fighting was reported in the flashpoint southern belt, as loyalist forces pressed a months-long bid to dislodge rebels from the cityâ€™s outskirts.
Elsewhere, the army shelled rebel-held areas of the central city of Homs, focusing on the neighbourhoods of Juret al-Shiyah and Qussur, said the Observatory.
After the rebels lost the Khaldiyeh district this week, the army has pushed on with its bid to dislodge them completely from Syriaâ€™s third city.
In the northern province of Hasakeh, jihadists and Kurds clashed two weeks after the expulsion of radical Islamists from the strategic Kurdish town of Ras al-Ain, opening up a new front.
Syriaâ€™s main opposition group called on warring parties in the north to â€œexercise restraint … to ensure the safety of civilians and secure the release of detaineesâ€.
Earlier this week, jihadist groups linked to al-Qaeda took hostage some 200 Kurdish civilians in the northwestern province of Aleppo.
The Coalition had so far been silent on the Kurdish-jihadist fighting, but on Saturday it said â€œAssadâ€™s militias … are the only target that Syriansâ€™ guns should be aimed atâ€.
More than 100,000 people, most of them civilians, have been killed in Syriaâ€™s 28-month conflict, the United Nations says.
On Friday alone, at least 110 people were killed across Syria, the Observatory said.
