A group of heavily-armed men — riding on a motorcycle and in three cars — went on a shooting rampage at a bar in Brazil, killing at least 11 people on Sunday, according to officials.

The “massacre” unfolded in the country’s northern Pará state in the city of Belem, the public safety department said. Authorities did not release a motive.

Seven men were said to have carried out the 4 p.m. attack, according to Brazilian news outlet G1, which cited Pará officials. Six women and five men were killed. Officials said almost all of them were shot in the head.

Police managed to wound one of the alleged gunmen and took him into custody, but the others reportedly got away. The bar that they targeted is in a high crime area, which had to get police reinforcements earlier this year, according to G1.

Cops were still investigating the shooting on Sunday night.
