On 16 Feb 15, the Lebanese Armed Forces allegedly arrested the sister of Abu Malek al-Talleh, the Nusra Front’s commander for the Qalamoun region, and her son at a checkpoint at the entrance to Arsal’s outskirts. The two were detained when they were heading toward Arsal’s outskirts at an Army checkpoint in Wadi Hmeid. LAF units across Arsal, and especially by the entrances to the outskirts, were allegedly mobilized in anticipation of a possible revenge attack over the arrest. The military was working on confirming the identity of the detained woman and her son.
