Two teenagers have opened fire at a school in south-eastern Brazil, killing at least five students and one employee, police say.
The shooting happened at about 09:30 local time (12:30 GMT) when the students were in a break at the state school in Suzano, near São Paulo.
Several other people have been wounded. The two gunmen killed themselves after the attack, police say.
While gun crime is common in Brazil, shootings of this nature are not.
The school has primary and secondary students, and the identities of the victims and the alleged attackers have not yet been released.
It is not clear the motive of the shooting, police say.
“I was in the classroom during our break. I thought [the sound] was from bombs. When I realized they were gunshots, I stayed there. I only left when the police arrived,” teacher Sandra Perez told O Estado de S.Paulo newspaper (in Portuguese).
São Paulo state governor João Doria tweeted that the victims had been “cruelly murdered”.
“When I arrived at the school… it was chaotic. Teachers, workers, everybody was running,” Juliano Simões de Santana, who lives near the school, told Folha de S.Paulo newspaper (in Portuguese).
