Armed gunmen ambushed a police convoy in Sinaloa, west Mexico, killing 12 police and one bystander.
According to reports, the police convoy was traveling on Friday from the city of Los Mochis when they were ambushed at a fake checkpoint set up near the town of Guasave. Two other agents had been wounded earlier that day in an attack in Los Mochis.
Bystander Alvaro Gallardo, a civilian employed at a nearby tortilla stall, was killed in the crossfire.
The agents were returning from escorting State Security Secretary Francisco Cordova Celaya. The secretary was unharmed, however, having returned to the city of Culiacan earlier that day via helicopter.
The governor of Sinaloa said that the killings were carried out because organized crime had found "no echo of complicity" among the state's security agencies.
