US-led coalition air strikes hit a bakery in the city of Tabqa in Raqqa province on Wednesday, killing at least 40 people including its owner, workers, and people queuing for bread, according to local sources and a war monitoring group.
Another air strike targeted a school housing displaced people late on Monday in the west of Raqqa, killing at least 33 people, the Syrian Observatory for Human Rights said.
Although the school is located in a Daesh-held area, local sources said there were no militants in the area at the time of the attack.
Anti-Daesh coalition spokesman US Army Colonel Joe Scrocca said he was unable to confirm the strike on the school was a coalition action, but confirmed the coalition had carried out strikes in the area.
"We have not been able to look at all the evidence to determine whether that was one of our strikes or not," he said.

The attack comes a week after another US air strike reportedly hit a mosque in the rebel-held village of Al Jina in Syria's northwestern Aleppo province.
At least 42 people were killed and dozens injured in the mosque attack.
