It took five hours of queuing at a community kitchen in Gaza's Nuseirat district for displaced grandmother Um Mohammad Al-Talalqa to get one meal to feed her hungry children and grandchildren. But finding food may be about to get even tougher: Gaza's community kitchens -- lifelines for hundreds of thousands of Palestinians after 18 months of war -- may soon have no more meals to provide. Multiple aid groups told Reuters that dozens of local community kitchens risk closing down, potentially within days, unless aid is allowed into Gaza, removing the last consistent source of meals for most of the 2.3 million population.
