"At least 85 people were killed, including 65 civilians, 10 of whom were children," when government helicopters dropped barrel bombs on rebel-held areas of Aleppo, the Syrian Observatory for Human Rights said Sunday.
Attacks using the controversial weapon targeted several areas of the city, once Syria's economic capital, with 34 of the dead in the Tareq al-Bab area alone.
The Observatory said 10 of those killed in Saturday's raids were jihadists from the Syrian al-Qaeda affiliate, Al-Nusra Front, who were in their headquarters when it was hit. Another 10 bodies could not be identified. (AFP)
