The senior leadership of one of the most influential Syrian rebel organisations has been wiped out in a devastating blast that is likely to greatly diminish the group as a fighting force.
The blast killed at least 12 senior leaders of Ahrar al-Sham, including its leader, Hassan Abboud, when it hit a meeting where the group had gathered inSyria's northern Idlib province, near the Turkish border.
The cause of the explosion remained unexplained almost a day later, with some Ahrar al-Sham members insisting a rival group had been responsible, while others claimed an explosion had mistakenly taken place in an adjoining ammunition base.
