Officials say a school bus carrying a driver and 45 students from a North Carolina middle school has overturned, injuring 15 of the children. Gaston County Schools spokesman Todd Hagans said the N.C. Highway Patrol determined that a compartment door above the driver fell open, creating a distraction before the accident Wednesday afternoon. Hagans says 11 students were taken to a Gastonia hospital and four more to a hospital in nearby Kings Mountain. None of the injuries appeared to be serious. He says the driver wasn’t hurt.
