The Austrian government has outlined plans to tighten gun laws in response to the deadly school shooting in the country's second-largest city of Graz. Chancellor Christian Stocker said on Wednesday the minimum age for the purchase certain types of firearms will be raised from 21 to 25 years,

Investigators say a former student who killed nine students and a teacher in Austria a week ago and then took his own life had become fascinated with school shootings in recent years.

After a shooter killed 10 people at a school in Graz, Austria's government is tightening rules on gun purchases by raising the minimum age and calling for more psychological screening.
