A government airstrike has killed tens of people in a town near the central city of Hama, anti-regime activists in Syria said.
The attack came as the main international envoy was beginning talks in Damascus aimed at ending the civil war.
The Britain-based Syrian Observatory for Human Rights said "tens of people" were killed in a strike by a fighter jet on Halfaya Sunday (local time).
An amateur video released online Sunday shows people rushing toward a building an off-camera narrator says is a bakery. The bodies of about a dozen dead or seriously wounded people lie in the street, some of them in puddles of blood.
Rubble and dust cover another pile of bodies along the building's wall. Residents and armed rebels carry the wounded away while others dig through the rubble looking for survivors.
