Security forces killed Ibrahim Abdul-Moti Abu Muaileq, a Palestinian Abdullah Azzam Brigades operative known as Abu Jaafar, in a shootout after he tried to elude arrest at a checkpoint in the Bekaa valley. Muaileq was accused of coordinating with the emir of the Islamic State of Iraq and the Sham on the movement of suicide bombers from Qalamoun in Syria into Lebanon. The arrest is part of an army effort to track down members of the Abdullah Azzam Brigades, which, like ISIS, has conducted suicide attacks in Lebanon in recent months. The World Health Organization predicted that 1.5 million Syrian refugees will enter Lebanon this year; already some 1.3 million have sought refuge in the country.
