At least 82 civilians, including children, were killed on Sunday in Syrian army airstrikes on a busy market in a rebel-held town near Damascus, a monitoring group reported.
The Syrian Observatory for Human Rights said that the strikes on the town of Douma on the eastern outskirts of the capital also wounded 250, dozens of them seriously.
Activists posted footage online showing what they said was the devastated market and buildings and mangled cars, with the area shrouded in plumes of dust.
The Syrian government has so far given no comment.
Syrian President Bashar al-Assad’s troops have stepped up air raids on Douma and other rebel-held areas near Damascus in recent months in retaliation for rockets fired by the insurgents on the capital.
