Almost the entire population of Gaza risks 'sliding into hunger hell' unless fuel deliveries are allowed to resume and there is a rapid increase in food supplies, an official from the UN's World Food Program warned on Thursday. The UN said 2.2 million Palestinians in the territory now need food aid to survive. Palestinians in the Gaza Strip are growing increasingly desperate in their attempts to obtain bread and other essential food supplies, and cases of dehydration and malnutrition are rapidly increasing 'by the day.' Aid trucks are 'trickling into Gaza,' but it is proving difficult to get the small amounts of food and water that cross the border to those in need because roads have been damaged by the war and fuel is in very short supply as a result of the Israeli blockade.
