A Syrian government air strike on a heavily contested neighbourhood in the northern city of Aleppo has killed at least 15 people, including nine children, activists said.
The Britain-based Syrian Observatory for Human Rights said the air raid hit Aleppo's Sheikh Maqsoud neighbourhood, which rebels seized parts of last weekend after days of heavy fighting with regime troops.
That gain had been the latest opposition advance in an urban war zone that expanded last summer, when rebel fighters took control of several neighbourhoods. Aleppo is Syria's largest city and a key front in the civil war raging between president Bashar Assad and those trying to overthrow his regime.
The Observatory said the death toll from the air raid, near a checkpoint of anti-government Kurdish militiamen known as the Popular Committees, is expected to rise as many others were seriously wounded.
An amateur video of the raid showed people loading the bodies of three bloodied children and two men in the back of a pick-up truck as women screamed and explosions went off in the distance. Another boy was seeing lying dead in the street near a burning truck.
The video appeared genuine and corresponded to other reports.
