 A troubled effort to get much-needed humanitarian aid into Gaza by boat appears to be ending. Several U.S. officials speaking on condition of anonymity say the pier built by the American military will be reinstalled today, but after several days, the plan is to remove it permanently. Sources say the goal is to clear whatever aid has piled up in Cyprus and on a floating dock offshore and get it onto the beach. The project has been hampered by heavy seas and security threats.
