Nine students were killed — six girls and three boys aged between 14 and 17, one with Polish citizenship — as well as a teacher, police said. Another 11 people were wounded.

A 21-year-old former student, named Arthur A. by the local media, shot and killed 10 people at a high school in Graz, Austria, before taking his own life. It is one of the deadliest school shooting in the country’s history.
