BEIRUT: At least 29 Syrian rebels were killed in a blast at a border crossing with Turkey on Thursday, the Syrian Observatory for Human Rights said.
The Britain-based monitoring group said it was unclear what caused the explosion at the Atme crossing between Turkey and the northern Syrian province of Idlib, adding that around 20 people had also been wounded.
The Islamic State jihadist group, which has been fighting the rebels and their Turkish allies, said a “soldier of the caliphate” detonated a car bomb as the rebel fighters were crossing into Syria, US-based monitor SITE Intelligence Group reported.
The IS statement said several commanders of the Islamist Ahrar al-Sham rebel group were among the dead.
Turkey’s state-run Anatolia news agency said the deadly blast took place during a “change of guard” among Syrian rebels in the area.
Rebel fighters have been targeted at the crossing before. IS claimed responsibility for a mid-August suicide attack there that killed at least 32.
