BEIRUT (AP) — Activists say a suicide car bombing by an al-Qaida-linked group has killed at least 20 rebels amid clashes in opposition-held areas in Syria.
Rami Abdurrahman of the British-based Syrian Observatory for Human Rights said on Wednesday that the bombing took place the previous day near the northern city of Darkoush.
Abdurrahman says the attack was carried out by the al-Qaida fighters from the Islamic State in Iraq and the Levant, who have been battling rebels from an array of Syrian rebel brigades, once their allies, since Friday.
The Local Coordination Committees also confirmed the bombing.
The rebel-on-rebel clashes across northern Syria are the deadliest infighting since the uprising against Syrian President Bashar Assad began in 2011.
Abdurrahman says at least 300 people have been killed in the infighting.
