BEIRUT - Al-Qaida-linked militants have executed the commander of a rival rebel faction and six of his men, an amateur video of the public execution showed, part of their campaign to marginalize other groups.
The Islamic State in Iraq and the Levant, or ISIL, fighting to overthrow President Bashar Assad, have taken advantage of a power vacuum in rebel-held areas to assert its authority over more moderate elements of the armed opposition.
The video, posted online by the anti-Assad Syrian Observatory for Human Rights monitoring group on Wednesday, shows armed men in black standing below an ISIL banner.
The Observatory said the video was taken in the northern Syrian town of Atarib in Idlib province. Its authenticity could not be independently confirmed.
