A U.N. official says 47 Palestinians were wounded, mostly by gunfire, when crowd overran Gaza aid hub. Ajith Sunghay, head of the U.N. Human Rights Office for the Palestinian territories, said it appeared that Israeli army fire had caused most of the injuries. On Tuesday, crowds of Palestinians overwhelmed a new aid distribution hub set up by an Israeli and U.S.-backed foundation. The crowd broke through fences and an Associated Press journalist heard Israeli tank and gun fire, and saw a military helicopter firing flares. The distribution hub outside Gaza’s southernmost city of Rafah was opened the day before by the Gaza Humanitarian Foundation, which has been slated by Israel to take over aid operations.
