GRAZ, Austria (AP) — Authorities in the Austrian city of Graz say a former student opened fire at a school, killing 10 people and wounding 12 others before taking his own life. Special forces were among those sent to the high school after a call at 10 a.m. Tuesday. Police say the assailant was a 21-year-old Austrian man who used two weapons, which he appeared to have owned legally. There was no immediate information on his motive. The BORG Dreierschützengasse high school is a short distance from the historic center of Graz, which is Austria’s second-biggest city with about 300,000 people.
