Prison fight in northern Mexico kills 31 inmates

RIO BRAVO, Mexico,  (Reuters) – A fight between rival gangs inside a prison in  northern Mexico left 31 inmates dead in the latest violence to  erupt inside the country’s overcrowded jails, local officials  said yesterday.

Clashes between prisoners wielding knives and homemade  weapons started around mid-day and were controlled several hours  later in Altamira, Tamaulipas, on Mexico’s Gulf coast, said  state government spokesman Guillermo Martinez.

Thirteen other inmates were wounded, the state government  said.

Powerful drug cartels are fighting for control of smuggling  routes along the U.S.-Mexico border and rivalries often spread  into the prison system, where prisoners held on federal drug  charges are mixed with common criminals.

Last October, twenty died in a prison fight at another jail  in Tamaulipas and in July, 17 inmates were killed in Ciudad  Juarez, Mexico’s most violent city, across from El Paso, Texas.

More than 46,000 people have died in Mexico in the past five  years since President Felipe Calderon launched a frontal attack  on drug gangs. Packed and inefficient prisons often suffer from  corruption and mass escapes.

Violence exploded in Tamaulipas state after the Zetas gang  broke away from the Gulf cartel and began battling their former  employers for turf.
