CIUDAD JUAREZ - Seventeen people have been killed in a prison gunfight in Ciudad Juarez, Mexico's most violent city, authorities said on Tuesday.
A spokesman for the mayor's office said an unspecified number of inmates entered two pavilions containing 13 other prisoners late on Monday, and a fight began. Sixteen men and one woman were killed in the ensuing violence.
The city on the border with Texas has been racked by a brutal turf war between the local Juarez cartel, and the powerful Sinaloa cartel, headed by Mexico's most wanted drug boss, Joaquin "Shorty" Guzman.
More than 40,000 people have died in drug-related killing since Mexican President Felipe Calderon sent in the army to crush the cartels shortly after taking office in late 2006. Roughly a quarter of the deaths have been in Ciudad Juarez.
