A gunman attacked a school in Graz, Austria, killing 10 people, including students. The 21-year-old attacker legally owned the weapons used, raising concerns about Austria's gun laws. Graz Mayor Elke Kahr is advocating for stricter regulations, citing that gun licenses are issued too quickly. Austria has approximately 1.5 million registered weapons, with a notable increase in recent years. The country’s gun laws are considered more liberal compared to other European nations. The attack has prompted national mourning and condemnation from Austrian authorities.
