Israel temporarily opened a border crossing with Gaza today to allow a limited supply of humanitarian aid to reach the territory. Thirty trucks, including eleven from the United Nations, were allowed to travel into Gaza. On Friday, the United Nations Relief and Works Agency announced it had run out of food and was unable to replenish storage facilities because of the Israeli blockade. The UN provides food aid to 750,000 Palestinians. Israel says the blockade is needed because Palestinian militants continue to fire rockets at nearby Israeli towns.
