A chief of a hardline jihadist alliance, including the al-Qaeda-linked Fatah al-Sham Front, on Friday baulked at talks aimed at ending Syria's conflict of almost six years and vowed to continue fighting.
"Peace negotiations and conferences will not close the page on the revolution," Hashem al-Sheikh, the head of the recently created militant bloc, the Levant Liberation Body, said in his first video recording.
He vowed to step up attacks against the Syrian government forces and their allies.
"The Body [alliance] seeks to lead the military and political action of the Syrian revolution in order to fulfil its aims of toppling the regime and liberating the Syrian lands."
Al-Sheikh's remarks come as the Syrian opposition meets later Friday in Saudi Arabia to discuss and name a team that will attend peace talks due to be held under the auspices of the United Nations later this month in Geneva.
Al-Sheikh is an ex-commander of Ahrar al-Sham, a conservative Islamist movement that has been locked in fighting against the Fatah al-Sham Front in northern Syria in recent weeks.
Last month, the Fatah al-Sham Front unified ranks with four rebel groups, including the powerful Noureddine al-Zinki movement.
Fatah al-Sham and the Islamic State extremist militia are excluded from an ongoing shaky ceasefire in Syria.
