"For the past five years, all entrances to Nahr al-Bared have remained encircled by the Lebanese army. It has remained that way since the military's 2007 campaign - ostensibly against Fatah al-Islam members - devastated the camp, turning it into a closed military zone. In addition to the checkpoints, walls and barbed wire, the army commandeered all the homes surrounding the periphery of the camp, in addition to those homes straddling the border between the old and new sections of the camp. Those wishing to visit friends in the camp must first obtain permission from the army (and those who are US citizens must wait for the army to clear visits with the US embassy). Palestinians from other camps, including those who lived in Nahr al-Bared prior to the army's bombardment, are also prevented from visiting the camp. Thus, people in other camps cannot visit their relatives in Nahr al-Bared without prior permission from the military."
