A teenager armed with a handgun and shotgun killed a fellow student and wounded five other people at a high school in the midwestern US state of Iowa on Thursday, authorities said. The shooting at around 7:30 am triggered a major police response as emergency vehicles and armed units rushed to Perry High School, where classes had not yet started for the day. The victim who died was in sixth grade, meaning aged 11 or 12, and was likely in the high school for a breakfast program, said Mitch Mortvedt, assistant director of the Iowa Division of Criminal Investigation.
