At least six suspected criminals were killed and one other was wounded in a shootout in the western Mexican state of Jalisco, officials said.

The Jalisco Attorney General's Office and state police said the clash occurred Friday afternoon on the Guadalajara-Tequila highway, where an armed commando attacked a group of men riding in several vehicles.

After the shootout involving automatic rifles and grenades, the aggressors fled in the direction of the neighboring state of Nayarit.

Several vehicles, including a motorcycle and a charred van with three bodies inside, were found at the scene.

Authorities said they suspect the shootout pitted organized crime gangs because a grenade launcher and several rifles and handguns were found inside the vehicles. EFE
