Dozens killed in Syria air strike
Dozens of people have been killed in an air strike on a village held by Islamic State in eastern Syria, activists say.
It was not clear who was behind the attack in Khansaa in Hassakeh province, which left between 30 and 80 dead.
The Local Co-ordination Committees and the Syrian Observatory for Human Rights said Syrian military helicopters had dropped barrel bombs on a market.
But some residents alleged that warplanes from the US-led coalition battling IS had fired missiles.
Syrian government officials have so far not commented on the incident.
