At least 20 people, most of them rebels, were killed in a car bomb attack that targeted an opposition checkpoint in northern Syria.
The blast – which hit a checkpoint run by the Levant Front, a group connected to the Free Syrian Army (FSA), near the city of Azaz on the road to the Bab al-Salamah crossing into Turkey, sent dozens of wounded to nearby hospitals.
At least 14 of the dead were believed to be rebel fighters. The death toll was likely to rise because of the number of seriously injured.
The area is a stronghold of Turkish-backed Syrian rebels involved in a major operation aimed at clearing ISIS from the border region.
