At least 19 people have been killed in an air strike in a village in Syria’s rebel stronghold of Idlib overnight, a rescue service there and the Syrian Observatory for Human Rights said on Wednesday.

The strikes pounded Maar Shureen in the northwestern Idlib province and injured 25 other people, the Britain-based Observatory said. The dead included seven children, it said.

The war monitoring group added that Syrian government or Russian aircraft had struck the village. There was no immediate comment from the Syrian military or Moscow, which have both repeatedly said they only target militants.
