Investigators have found the black box of the passenger jet crashed into the Margalla Hills surrounding Islamabad Wednesday, killing all 152 people on board. Initial Interior Ministry reports that five people survived the Airblue crash were wrong, said Imtiaz Elahi, chairman of the Capital Development Authority, which deals with emergencies and reports to the ministry. "The situation at the site of the crash is heartbreaking," Elahi said. "It is a great tragedy, and I confirm it with pain that there are no survivors." The dead included two U.S. citizens, said the U.S. Embassy in Islamabad without providing further details.
