A Jordanian security official says a Palestinian gunman who shot himself after wounding six people in Jordan's capital last week has died of his injuries. The official says 19-year-old Thaer al-Weheidi died at a hospital on Tuesday, a day after undergoing surgery to stop a brain hemorrhage caused by the bullet wound. He spoke on condition of anonymity because the investigation into the shooting was continuing. Al-Weheidi shot and wounded six people outside Amman's Roman amphitheater on July 16. He shot himself in the head when police tried to subdue him. He had been in a coma since. Police are investigating whether he had links to extremist groups after initially saying he had none.
