25 inmates die as rival factions clash

At least 25 inmates died on Sunday in clashes between two rival factions in a prison in far northern Brazil, the latest episode of violence shaking the country's underfunded and overcrowded prison system.

Seven of the dead were beheaded and six burned to death in fighting at a prison in Boa Vista, the capital of Roraima state, the news site G1 reported, citing local police.

The bloodshed began when inmates of one wing of the Agricola de Monte Cristo prison broke into another wing.
