Rescuers searched Saturday for people believed to be trapped in a partially collapsed hospital after a powerful tornado ripped through a community in the U.S. state of Kansas. At least one person was reported killed and dozens were injured. The tornado struck Greensburg on Friday night, leaving a broad swath of destruction in the Kiowa County town about 110 miles (175 kilometers) west of Wichita. The storm front spawned tornadoes along a path stretching northeast from Greensburg through central Kansas. Phone service to the town of about 1,600 residents was knocked out, and the state's department of transportation was trying to restore emergency service, the Associated Press reported.
