At least six children and two teachers have been killed after two gunmen stormed a school in Brazil.

Authorities said the hooded attackers opened fire at the Raul Brasil public grade school in Suzano on the eastern outskirts of Sao Paulo before killing themselves.

Sao Paulo governor Joao Doria said the pair were believed to be between 20 and 25 years old.

Marcelo Salles, commander of police forces in Sao Paulo state, described it as an "unspeakably brutal crime".

He said the gunmen were armed with at least one pistol, homemade bombs and a crossbow.


They are not believed to be former students.

A further 17 people, mostly children, were shot and injured - with several of those in a serious condition.

Rosni Marcelo Grotliwed, a student at the school, said: "We were at recess and eating like normal and we heard three pops, then we tried to run to jump over the walls."

She said that she saw many dead bodies when she ran to the principal's office.

"My friend was stabbed in the shoulder and my other friend was shot," she said. "I escaped with one friend and went home and then came back to look for another friend."
