Austria’s chancellor says his country will toughen its gun laws after a 21-year-old former student killed nine students and a teacher at his school last week in what’s considered the Alpine country’s deadliest post-war attack.

Officials in Austria say a school shooting has left at least 10 people dead in the European nation's second-largest city, Graz. The shooter is also dead.

Residents of Graz gathered for a mass and a candle lit vigil to mourn the 11 victims who were killed after a former pupil opened fire in a school. View on euronews
