13 Dead After Prison Fight in Brazil
At least 30 injured
Thirteen inmates have been killed and at least 30 injured in a fight between rival gangs in a prison in Brazil.
Riot police say they have regained control of Pedrinhas prison in Sao Luis, in the state of Maranhao, and are searching the jail for illegal weapons.
Prison guards said fighting had broken out after they discovered inmates digging an escape tunnel.
Brazilian prisons suffer from extreme overcrowding and riots and gang warfare are not unusual.
