A man opened fire in a cathedral in southern Brazil after mass, killing four and leaving four others injured before turning a gun on himself, authorities said.
The shooting occurred right after mass at the Metropolitan Cathedral in Campinas, a city about 60 miles north of Sao Paulo, according to Wilson Cassante, a spokesman for the archdiocese.
He said the officiating priest had left before the shooting began.
A spokesman for Sao Paulo state firefighters said four injured people had been taken to local hospitals.
Their conditions were not immediately known.
“It’s so sad,” said Mr Cassante.
“It’s hard to imagine the pain this has caused.”
Hamilton Caviola Filho, a police investigator, told news portal G1 that authorities had reviewed surveillance footage from inside the cathedral.
The investigator also said that before shooting himself in the head, the suspect took a bullet in the ribs from responding police.
In total, the suspect fired at least 20 shots, said Mr Caviola Filho.
Firefighter Alexandre Monteiro told G1 that the four injured were in stable condition.
The motive was not clear.
Authorities have yet to release the name or age of the suspect.
While Brazil leads the world in total annual homicides, mass shootings are relatively rare.
