MEXICO CITY -- A violent clash between rival prison gangs has left at least 14 inmates dead at a penitentiary in the Mexican border city of Matamoros, across the border from Brownsville, Texas.
A spokesman for police in the Gulf coast state of Tamaulipas says there is no information yet on the number of injured in the fight.
The clash began early Friday morning. The spokesman said it involved inmates charged with or serving sentences for federal crimes, which in Mexico include everything from drug trafficking to weapons possession.
The spokesman said that the inmates used knives, clubs and other weapons that may have been made from scrap materials inside the prison.
