The Lebanese Army has arrested an ISIS commander in the northeastern village of Labweh, the state-run National News Agency said Saturday. The report said the detainee was heading from the town of Arsal, adjacent to Labweh, to north Lebanon when he was arrested at an Army checkpoint. LBCI and other Lebanese media later identified the man as Abdel-Rahman al-Bezerbashi, 21, an ISIS member who goes by the nickname "Baghdadi's grandson." They said Bezerbashi had participated in attacks on the Army in both Tripoli and Arsal. A security source told The Daily Star that he could not confirm the affiliation or rank of the detainee, but said he was "suspected of having links to Syrian rebel groups." He added that the man was not carrying any identity card at the time of the arrest. ISIS has been present outside Arsal for more than one year. In August 2014, militants from ISIS and the Nusra Front briefly overran Arsal, sparking a 5-day battle with the Lebanese Army that left dozens dead. The groups abducted more than 30 Lebanese troops and policemen during the battle and transported them to the town's outskirts where around 25 are still being held hostage. Four of the original hostages have since been killed - two by ISIS and two by Nusra - and eight released.
