An attack in the western Mexican municipality of Concordia left four men dead and two others badly wounded, sources in the Sinaloa state Attorney General’s Office told Efe.
Three men were declared dead at the scene and the fourth died later at a hospital in the resort city of Mazatlan.
Two other men present at the time of the assault were abducted.
Emerging from the surrounding mountains in several vehicles, the attackers, armed with assault rifles, opened fire on six men who were standing outside a home, police said.
An SUV sitting outside the residence had multiple bullet holes.
Authorities from Sinaloa and neighboring Durango state established a security perimeter around the crime scene and launched an investigation.
Both the victims and the attackers were apparently hired guns for rival criminal organizations, according to media accounts that cited unnamed military sources.
The Sinaloa cartel dominates drug trafficking in its home state and is Mexico’s largest and wealthiest criminal outfit.
Led by most-wanted fugitive Joaquin “El Chapo” Guzman, the cartel is a transnational business empire that operates in the United States, Europe, the Americas and Asia.
