RIO DE JANEIRO - A gunman fatally shot 12 people at a Rio de Janeiro school before killing himself, police said Thursday.
The incident apparently was unrelated to the city’s gang violence.
“A former student entered the school with a weapon. It is not known why he fired,”. He said at least 20 people were wounded in the attack.
Police exchanged gunfire with the assailant, who was carrying two guns and a suicide note, before he killed himself, another police official told local media.
