Dozens of prisoners have been killed in a prison riot in northern Brazil, according to the Associated Press.
At least 52 prisoners were killed in the riots, which broke out on Monday.
The riots were between organized crime groups, and 16 of the victims were decapitated.
As the riots broke out, “inmates… set fires that prevented authorities from entering part of the facility for about five hours.”
Authorities say the death toll could rise as they continue to search the prison.
