UN aid workers are turning away thousands of Gaza residents meant to pick up food from UN distribution centers because the international organization has run out of supplies. Some 20,000 people were meant to pick up rice, flour, sugar and oil on Saturday from a UN agency that distributes aid in Gaza. In all, some 750,000 Gazans are elible for food aid. But the UN said it does not have enough food to distribute because of the closure of Gaza by Israel. Israel has kept its border crossings closed for the past 11 days because Palestinian terrorists are firing rockets from Gaza at nearby communities. Gaza's power plant has also shut down because it has run out of industrial fuel.
