Austria reels from ‘national tragedy’ after gunman kills nine at former school

Worst mass shooting in country's recent history leaves 10 dead, including 21-year-old man who police say shot himself after killing nine others

Austria will hold three days of national mourning after a 21-year-old man shot dead eight pupils and an adult at his old high school and injured a dozen more before turning his weapon on himself.

Visibly moved at a media conference, the chancellor, Christian Stocker, announced a minute's silence for 10am on Wednesday to start the period of mourning for the victims of Austria's deadliest postwar mass shooting.
