Daesh and Jabhat Fatah al-Sham militants engaged in fierce clashes Tuesday along the northeastern Lebanese border with Syria, Hezbollah-run media reported.
The War Media Center said on its Twitter account that the clashes in the Al-Dib and Al-Khayl valleys in the northern part of Arsal's outskirts left militants dead and wounded, adding that Jabhat Fatah al-Sham managed to take over two ISIS positions.
Jabhat Fatah al-Sham was formerly known as the Nusra Front, which was affiliated to Al-Qaeda.
The two extremist groups often clash in the rugged border region, usually over land disputes.
While Jabhat Fatah al-Sham has a strong presence around Arsal, Daesh has foothold on the outskirts of the nearby town of Ras Baalbek.
The militants are targeted by the Lebanese Army and Hezbollah on a nearly daily basis to keep them at bay.
