The leader and top commanders of Syrian Islamist insurgents Ahrar al-Sham have been killed in a suicide attack Tuesday. The BBC reports:

Hassan Abboud, the leader of the Syrian Islamist insurgents Ahrar al-Sham has been killed with other top commanders in a bomb blast at a meeting.

Activists say a suicide bomber detonated a vest in the attack in the north-western town of Ram Hamdan.

Ahrar al-Sham is part of the Islamic Front, a coalition of seven Islamist rebel groups.

In February, Ahrar al-Sham blamed the rival Islamic State group for an attack which killed several of its members.

Ahrar al-Sham is one of the biggest rebel groups fighting the government of President Bashar al-Assad.

Although the group is hard-line Islamist in orientation, it has opposed and clashed with the ultra-radical Islamic State (IS) group, which is the most likely quarter to be blamed for the attack, reports the BBC’s Jim Muir.
