California Governor Jerry Brown signed several gun control bills into law, including one measure that raises the minimum age for buying rifles and shotguns from 18 to 21, Reuters reports.
The new laws come seven months after a gunman opened fire with a semiautomatic assault-style rifle at Marjory Stoneman Douglas High School in Parkland, Florida, killing 14 students and three adults, the second-deadliest mass shooting at a public school in U.S. history.
The rampage, which authorities say was carried out by a former student who was 19, has spurred unprecedented activism by victims and their families to prevent future gun violence and demanding stricter gun control across the United States.
