At least 14 people have died in a shootout between police and rival drug gangs in Mexico.
The shootout took place near Las Varas which is infamous for being Mexico's drug trafficking region.
Investigators believe the groups involved in the shootout were "La Linea" -- the armed wing of the Juarez cartel -- and hitmen from the powerful Sinaloa cartel, Esparza told AFP.
Both groups opened fire on officers when they arrived on the scene, state police chief Oscar Aparicio told AFP
"We can't rule out that there are more people dead. It was a very intense confrontation. There were more than 60 (gunmen)," he told Mexican radio network Formula.
Last Friday, 17 gunmen were killed in a shootout with police on a highway in Sinaloa.
Mexico has seen a series of shootouts after Joaquín Archivaldo Guzmán, a drug lord who headed the Sinaloa Cartel, was extradited to the United States in January, since then rival drug gangs and inter-gang rivalry within the Sinaloa cartel has led to several deaths and police shootouts.
