The United Nations expects to soon distribute the aid brought by a Turkish flotilla trying to run the Gaza blockade and seized by Israel after a bloody confrontation. Robert H. Serry, the United Nations envoy to the Middle East peace negotiations, told the United Nations Security Council on Tuesday that despite such attempts, Gaza received only a fraction of its needs. Three-quarters of the damage caused by the 2009 war— including homes schools and hospitals — has not been repaired or rebuilt, Mr. Serry reported. In roughly the past month, he said, an average of 566 trucks of goods entered Gaza weekly, a 6 percent drop from recent numbers.
