At least 12 school children were killed on Monday in an airstrike on a school in Syria's Aleppo province, a monitor group reported.
The air raid targeted the school in the town of Ankara in the countryside of Aleppo, said the Britain-based Syrian Observatory for Human Rights, which says it relies on activists on the ground inside Syria.
The pro-opposition Observatory report, which said the raid was conducted by Russian aircraft, cannot be independently verified.
