The Lebanese army detained an Islamic State-group leader and 11 other militants in a dawn raid on Friday near the town of Arsal on the Syrian border, security sources said.
Ahmad Yousef Amoun, the Islamic State-group leader, was wounded in a shootout during the raid. The army seized a large quantity of weapons and explosive belts, the sources said.
The town of Arsal was the location of a major attack by jihadists from Islamic State-group and the al Qaeda-linked Nusra Front in 2014.
Islamic State group is still holding nine Lebanese soldiers kidnapped by the group during the attack.
