The Suqour al-Sahel brigade has joined rebels with the Islamist Front in their war on the Al-Qaeda-linked splinter group, the Islamic State of Iraq and Greater Syria (ISIS), it said in video statement seen by Zaman al-Wasl.
Saeed Tarboush, the leader of the group based on Syria's coast, has addressed ISIS militants in Latakia countryside, urging them to give up fighting or face death.
ISIS controls many areas in Akrad Mountain area and the villages of al-Najjiya, Badama, Salma and Ghassaniye.
Suqour al-Sahel attacked an ISIS barracks on the highway between Aleppo and Latakia.
While ISIS was once welcomed by rebels battling Syrian President Bashar Assad, excessive abuses by the group turned much of the opposition fighters against them. It has alienated many civilians and opposition activists by imposing harsh rulings against dissent in areas it controls, including beheadings.
