Latest updates on cartel activity in Arizona and Mexico as of early February 2026

Latest updates on cartel activity in Arizona and Mexico as of early February 2026, based on recent reports from news sources, government announcements, and investigations.

In Mexico, Mexican drug cartels, particularly the Sinaloa Cartel and Cártel de Jalisco Nueva Generación (CJNG), continue to dominate headlines with ongoing violence, arms acquisitions, and internal conflicts.

• A major investigative report (published around February 7-8, 2026) from the International Consortium of Investigative Journalists (ICIJ), The New York Times, and others highlights how cartels are overpowering Mexican police and civilians using .50-caliber ammunition produced at the U.S. Army's Lake City Army Ammunition Plant in Missouri. This ammo, which can pierce armored vehicles and is designed for military use (including armor-piercing incendiary rounds), has been smuggled across the border and seized in large quantities in U.S. border states. Incidents include attacks on police convoys in 2024 and earlier events like the 2019 Villa Unión massacre. This has escalated concerns about arms trafficking and cartel militarization.

• Cartel violence persists in regions like Sinaloa (due to factional infighting after the arrest of leaders like Ismael "El Mayo" Zambada), Guanajuato, Michoacán, and Chihuahua. Recent examples include:

  • Dismantling of cartel camps in Chihuahua (early February 2026), some involving drugs and shrines.

  • Drone usage by cartels for attacks, surveillance, and dropping explosives (e.g., incidents in Chihuahua injuring officers; also concerns in New Mexico border areas about drones crossing into the U.S. for smuggling guidance or criminal acts).

  • An apparent CJNG explosive attack on rivals in Cotija, Michoacán (circulating online in early February).

• U.S.-Mexico cooperation has intensified under pressure from the Trump administration (which designated several cartels as foreign terrorist organizations). Mexico transferred 37 alleged cartel members to U.S. custody in January 2026 (the third major handover, totaling 92 since early 2025). These include figures from Sinaloa, CJNG, Beltrán-Leyva remnants, Northeast Cartel, and others charged with narcoterrorism, drug trafficking, human smuggling, money laundering, and firearms offenses. Arrests continue, such as a major Sinaloa-linked fentanyl producer in Badiraguato, Sinaloa (January 19, 2026).

• Broader trends include cartels adapting money laundering via cryptocurrency and ongoing internal wars (e.g., Sinaloa factions, CJNG vs. rivals).

In Arizona

Activity in Arizona focuses more on smuggling, trafficking enforcement, and spillover effects rather than widespread open violence on U.S. soil (cartels generally avoid high-profile violence here to protect business operations).

• Cartels like Sinaloa maintain strong influence in drug distribution, with Arizona described as "ground zero" for trafficking by DEA officials. Recent enforcement includes intensified DEA operations against Sinaloa networks, with higher arrests in 2025-2026 compared to prior periods.

• Border incidents include:

  
  

  • A January 2026 traffic stop in southern Arizona rescuing an 8-year-old boy in a suspected cartel-linked human trafficking case.

  
  

  • Occasional shootings or pursuits near the border (e.g., a justified Border Patrol shooting in southern Arizona after a suspect fired at agents).

  
  

  • Ongoing concerns about gun trafficking from Arizona to Mexico (e.g., prior indictments of groups moving hundreds of firearms).

  
  

• Drones and smuggling tactics are raising alarms in neighboring New Mexico (and potentially Arizona), with cartels using them to guide operations or drop packages/explosives.

• No major new outbreaks of cartel-on-cartel or cartel-vs-law-enforcement violence were reported directly in Arizona in the very latest days (early February 2026), but enforcement remains high amid U.S. pressure on cartels.

The situation reflects heightened bilateral efforts to disrupt cartels (transfers, designations as terrorist groups, financial targeting), but challenges persist with advanced weaponry, drones, and adaptation to enforcement. Violence remains concentrated in Mexico, with Arizona primarily seeing smuggling and related enforcement actions.
