Government helicopter gunships have dropped bombs on the Syrian city of Aleppo, killing at least 10 people and wounding many others, activists said.
A barrel bomb struck a shop that sells fuel, according to an Aleppo-based activist going by the name of Abu Raed. He said a fire broke out and many bystanders were burned.
The strike on the Qadi Askar neighbourhood killed at least 10, he said, while the Britain-based Syrian Observatory for Human Rights said 18 people died.
The aerial attack comes a day after the Nusra Front, al Qaida's Syrian affiliate, and other radical Islamic factions launched an assault on a government intelligence building in Aleppo, blowing up part of it before trying to storm the facility.
