6 police officers shot dead amid cartel turf war in northern Mexico: "Cowardly attack"

Gunmen on Wednesday killed six police officers in a northern Mexican state where rival cartels are fighting over drug trafficking routes, authorities said. Five of the officers were shot dead while training at a sports center in Calera de Victor Rosales, the Zacatecas state government said.

Two more law enforcement officials were shot after arriving at the scene soon afterward, one of whom died, according to a statement.

Zacatecas Governor David Monreal condemned what he called a "cowardly attack" and offered his condolences to the family, friends and colleagues of the victims.
