In Brazil, two gunmen went on a shooting rampage Wednesday at a high school on the outskirts of São Paulo, killing eight people before turning their guns on themselves. At least 17 others were injured by gunfire during the assault, which saw panicked students climbing over the school’s walls and screaming to neighbors for help.

Unidentified student: “They just came out shooting, shooting. They didn’t look at anyone; they just started shooting at anyone who was close by.”

A police investigator said the two attackers—aged 17 and 25—were former students of the high school who were inspired by the 1999 Columbine massacre in Littleton, Colorado. In January, Brazil’s newly inaugurated far-right President Jair Bolsonaro signed a decree making it easier for people to keep guns at home.
