Municipal Education Secretary Gisela Hermann described a “horror scene” at the facility in Saudades, a city in the state of Santa Catarina. She told Reuters in a telephone interview that a female teacher and a teaching assistant were among the dead.
She added that other children would likely be hospitalized as a result of the attack.
Silvia Fernandes dos Santos, a local school board employee, said the attack happened around 6 p.m. 10 local time. The teenager was taken into police custody after attempting to kill herself, she said.
“He tried to … take his own life, but he could not. So he was sent to the nearest hospital to be transferred. People were very angry and they wanted to do their own justice,”
Police in the town of Chapecó near Saudades said they were investigating the incident but could not provide any information immediately. Santa Catarina’s public safety department did not respond to a request for comment.
