Syrian government aircraft dropped barrels packed with explosives on opposition-held areas of the contested northern city of Aleppo on Sunday, leveling buildings, incinerating cars and killing at least 37 people including 16 children, activists said.
Government forces pounded the opposition neighborhoods of Haidariya, Ard al-Hamra, Sukhour, Marjeh and at least two others with barrel bombs dropped from helicopters, Britain-based Syrian Observatory for Human Rights said. Observatory director Rami Abdurrahman said Syrian air force jets were also flying over the same districts.
The government frequently uses barrel bombs, which contain hundreds of pounds of explosives and cause massive damage on impact. The Aleppo Media Center, another activist group, said government aircraft dropped at least 25 barrel bombs on the city Sunday.
Civil defense volunteers told Al Jazeera they had not rested since the morning, as they tried to cope amid the bombardment.
"More than 10 different areas in Aleppo came under heavy bombardment," one member of the team told Al Jazeera. "They were shelled by both explosive barrels and missiles."
