At least eight children were killed along with a teacher in a Russian air strike that hit a school in Syria’s town of Anjara on Monday.
The Syrian Observatory for Human Rights said the strike had also left at least 20 more children and teachers injured.
The group also said there had been heavy air strikes and clashes between government and rebel forces since Sunday in the northern province, which is controlled by a mixture of moderate and Islamist rebels.
Syria’s Aleppo district, to which Anjara belongs, has been divided between government forces in the west in the west and rebel fighters in the east, after fighting began there in 2012.
Russia, an ally of President Bashar al-Assad’s regime, began air strikes in support of the government late last year.
Moscow says it is targeting ISIS and other militant outfits, but a third of those killed in its strikes have been civilians, according to the Observatory.
