An air strike in Syria's Hama province on Sunday has killed dozens of people queueing for bread from a bakery, reports Reuters.
If the initial death toll of 90 is confirmed, the attack would be one of the deadliest air strikes in the Syrian civil war.
Activists uploaded videos showing dozens of blood-stained bodies among piles of rubble and shrapnel.
Rami Abdelrahman, of the Syrian Observatory for Human Rights, said:
"It is still very unclear what the casualties are ... From looking at the videos I expect the death toll to be around or above 50, and not higher than 100. But for now I am keeping my estimate at dozens killed until we have more information."
The attacked town of Hafalya was seized by rebels last week in ongoing clashes between the Bashar al-Assad's military forces and opposition groups.
