Authorities at a Venezuelan prison have found the bodies of eight inmates killed in what officials say is a conflict between rival gangs fighting for control of their cellblocks.

National Guard Col. Juan Ramon Rivas said Saturday the bodies were discovered in an administrative area of the prison in western Tachira state. Authorities think the dead were moved there after being killed elsewhere in the prison.

The slain men found Friday all had stab wounds and belonged to the same gang.

Violence is common in Venezuela's severely crowded prisons, where inmates can obtain firearms and other weapons with the help of corrupt guards.
