Activists in Syria say a government jet has dropped a cluster bomb on a playground, leaving 10 children dead.
Video posted on the internet showed children's bodies on the ground with their mothers grieving over them.
The children were killed when a MiG fighter bombed a playground in the village of Deir al-Asafir, east of Damascus, opposition activists said.
Intensive fighting has continued around the capital. Rebel fighters captured at least part of an airbase on Sunday.
