A 17-year-old gunman dressed in black opened fire at his former high school in southwestern Germany on Wednesday, killing at least 15 people before police shot him to death, state officials said.
Nine students and three teachers were among the dead, State Interior Minister Heribert Rech said.
Baden Wuerttemburg governor Guenther Oettinger said police shot the suspect after he fled the school.
Helicopters searching for him crisscrossed the area, and police warned area residents not to pick anyone up in their cars. It was Germany's worst shooting since another teenage gunman killed 16 people and himself in another high school in 2002.
