Federal Government Reinforces Security Presence in Sinaloa Amid Ongoing Cartel Violence

Mexico's federal security cabinet committed on May 5, 2026 to maintaining and increasing military deployments across Sinaloa as cartel-related violence continued 20 months into the La Mayiza vs. Chapitos civil war. Al Jazeera and La Jornada reported visible military checkpoints installed across Culiacán and surrounding municipalities. The Sheinbaum administration authorized additional federal police and National Guard rotations to support Sinaloa state authorities. By this point La Mayiza had consolidated approximately 90% of former Chapitos-held territory, though sporadic gun battles continued. The reinforcement came amid broader calls from Sinaloa civil society for a comprehensive security strategy beyond troop presence.
