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 will set stricter eligibility rules for possession and purchase of arms, Chancellor Christian Stocker said.

Austria is grappling with a profound loss following a harrowing high school shooting that left eight people dead, seven of whom were students. The assailant also succumbed to a fatal outcome, ending the immediate threat.
