Forty-two people have been killed and many more injured in an air attack on a mosque in a rebel-held village in northern Syria, the Syrian Observatory for Human Rights says.
The raid is said to have taken place near Atareb town, in Aleppo province.
The UK-based observatory, which relays information from sources on the ground in Syria, said the mosque was packed with worshippers for evening prayers.
The group said most of those killed were civilians.
