Authorities said the number of dead could rise. Initial reports from the relatively isolated region had put the death toll as high as 26 but officials said later that only 14 bodies had been recovered yesterday
Oscar Alberto Aparicio, the Chihuahua state security commissioner, said security forces came under fire when they arrived at the scene of the clash in Las Varas, a town about 300 kilometers northwest of the state capital.
Soldiers and police "were met with gunfire, but they managed to beat back the attack and only one patrol vehicle was hit by gunfire," Aparicio said.
Felix Gonzalez, a spokesman for Chihuahua state prosecutors, told local media the initial confrontation pitted members the La Linea gang, based in the border city of Ciudad Juarez, against a faction of the Sinaloa cartel.

Another state prosecutors' spokesman, Eduardo Esparza, confirmed 14 bodies had been found, but added that "there could be more." He said all the dead were adult males. Twenty rifles were found at the scene, along with grenades and grenade launchers.
Aparicio said the gangs had apparently killed two state police officers who went up into the area to investigate about 10 days ago.
"These criminals were the ones who killed in a cowardly way two of our agents a week ago," Aparicio said, noting there were about 50 gunmen in one of the gangs.
