A deadly school shooting in Graz has pushed Austria’s gun laws— and its quiet gun culture — into the national spotlight.

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.

Authorities in Austria are investigating a school shooting by a 21-year-old gunman that left 10 dead, before the perpetrator took his own life in Graz. The nation observed a minute's silence as details of the tragedy emerged,

The Graz school shooter legally obtained two weapons despite being rejected for military service due to mental health concerns, Austrian authorities revealed.

"I think the first thing is shock, to be honest. I think you can't react the other way. I think everyone in the school is in complete shock," said 24-year-old student Helene Parr, who knows people at the BORG Dreierschützengasse school, where the mass shooting took place.

As Austria observed three days national mourning, investigators said they found a non-functional pipe bomb and a farewell letter at the shooter's house.

Mayor of Graz says presumed gunman among the dead as local media report 28 people are being treated for injuries.
