Officials in Guatemala say a brawl among inmates at an overcrowded prison killed six people and wounded several others.

Deputy Interior Minister Elmer Sosa says police and soldiers intervened after Sunday's bloodshed and restored order at the prison.

Prison system spokesman Rudy Esquivel says six inmates have been confirmed as dead at the prison, known as Granja de Rehabilitacion Canada. He says the prison was designed to hold 600 inmates but houses 3,092.

The spokesman says the fight apparently erupted between members of the Mara 18 and Mara Salvatrucha gangs and fellow inmates who don't belong to the gangs.
