A suicide bomber has rammed a car laden with explosives into a gathering of jihadist rebels near the rebel-held northwestern Syrian city of Idlib, killing at least 12 people and injuring many more.
They said the blast on Wednesday ripped through a textile factory where members of Hayat Tahrir al-Sham, an alliance of rebel groups whose backbone is the former al-Qaeda affiliate Nusra Front, had been using as their quarters.
The jihadist alliance has been waging in the past few days a major sweep to round up ultra-hard-line Islamic State sleeper cells in Idlib province.
Idlib province is dominated mainly by Islamist jihadist groups although there are some moderate Western-vetted Free Syrian Army groups.
The province, which borders Turkey, has long witnessed infighting between the main jihadist groups vying for power.
