Ten civilians were killed near Aleppo Friday when regime air raids hit a bus travelling on a key road out of the embattled northern Syrian city, the civil defence said.
The Syrian Observatory for Human Rights, a British-based monitoring group, also reported intense raids on the road but gave a lower toll of eight civilians killed.
The Castello road, where a bus was also hit by regime bombing raids on Wednesday, is a key rebel supply route out of divided Aleppo.
