An airstrike on a market in the northern Syrian province of Aleppo is reported to have killed more than people.
The Syrian Observatory for Human Rights in London said the market in the town of Atareb was hit early on Thursday morning, when it was busy. It said the death toll was 27.
Video images showed bodies lying on mounds of grey rubble.
Government forces have made gains recently, but rebels still control large territories. The war is now in its fourth year.
