At least 20 people were killed Saturday in airstrikes by Syrian government forces on a rebel-held area in the northern province of Aleppo, a pro-opposition watchdog group said.
The planes dropped barrels packed with explosives on a market and a hospital in the district of Tareeq al-Bab, in north-eastern Aleppo, added the Britain-based Syrian Observatory for Human Rights, dpa reported.
The dead included two children, one woman and a media activist, it said.
It expected the toll to rise, saying dozens were seriously injured.
Opposition activists claim that hundreds, mainly civilians, have been killed in Aleppo since late November in aerial attacks using barrels with explosives.
Aleppo, Syria's commercial hub, has been at the centre of fighting between the Syrian military and rebels fighting to topple President Bashar al-Assad.
According to the latest UN estimate issued in July, more than 100,000 people have been killed in nearly three years of conflict. The observatory put the toll at about 130,000 people.
