At least 16 people were killed in a blast at Atmeh village in north western Syria near its border with Turkey on Thursday morning, opposition activists said.
The explosion was caused either by a suicide bomber or a bomb set off using a remote control, Britain-based Syrian Observatory for Human Rights said. It added that the casualties also include rebels and that many people have been wounded, the Associated Press reported.
It added that rebels supported by Turkish groups who have been fighting against the Islamic State group (Isis) since August were also among the dead.
The Local Coordination Committees said that the explosion took place due to an explosives-laden bag that went off on the Syrian side of a border crossing.
