More than a quarter of aid sent to Gaza is being looted by mobs or stolen by gangs, UN officials have said. Gang violence has spiralled out of control, crippling supply lines on which most of Gaza's 2.1 million civilians rely for survival. Aid agencies are unable to resolve the problem of lawlessness in Gaza by themselves. In October, £7.5million worth of food and other goods - nearly a quarter of all the humanitarian aid sent to Gaza that month - was lost because of attacks and looting. Relief operations are hobbled by a disagreement between Israel and much of the international community over who is responsible for feeding civilians in Gaza and maintaining order in the tiny territory.
