Syrian rebels fighting the Islamic State of Iraq and Greater Syria (ISIS) in the north of the country on Wednesday killed a jihadist leader in the town of Saraqeb, activists said.

Abul Baraa, a Belgian jihadist of Arab origin, last week warned Syrian rebels to halt an anti-ISIS offensive they launched early January or face suicide attacks against their positions.

Since his January 6 warning, Islamist and moderate rebel positions have been hit by jihadists' suicide attacks -- mostly car bombs -- in Aleppo, Idlib and Raqqa provinces, which have killed dozens of opposition fighters.

Earlier that day, rebels fighting the jihadists withdrew from the province.
