Armed CJNG Members Storm Guadalajara Airport and Threaten to Force Entry Into Homes and Hotels as Mexico's Jalisco Descends Into Chaos

Sunday started like any other morning at Guadalajara International Airport — until it didn't. Videos that rapidly spread across social media showed workers in high‑visibility vests abandoning their posts and breaking into full sprints. Passengers ducked behind counters. Reports of armed men inside the terminal spread faster than authorities could contain them. Within hours, what was unfolding inside that airport had become the most visible symbol of something far larger — a cartel in open revolt.

The trigger was the death of Nemesio Rubén Oseguera Cervantes. Known to nearly everyone simply as 'El Mencho', the founder and leader of the Jalisco New Generation Cartel (CJNG) was killed earlier that Sunday in a military operation in Tapalpa, Jalisco. The Mexican Ministry of Defence said security forces came under fire and were compelled to defend themselves, with four CJNG operatives also killed in the exchange.

A Cartel's Ultimatum

The retaliation was neither random nor slow. Messages attributed to CJNG began circulating almost immediately, warning residents across Guadalajara and surrounding neighbourhoods to stay inside or face violence. One message, originating from Tesistán in Zapopan and reported by open‑source intelligence accounts on X, went further — threatening to force entry into homes and hotels by 17:00 if demands were not met. Another warning told anyone still on the streets after 14:00 that they would be targeted.

Video footage from Guadalajara International Airport shows employees sprinting for cover as reports spread of armed men inside the terminal, framed by captions describing a 'cartel meltdown' after federal operations targeting the group's leader. In response, the Jalisco state government activated a 'Código Rojo' — a Red Code alert representing the highest security threat level.

Smoke Over Puerto Vallarta

The violence was not confined to Guadalajara. In Puerto Vallarta, a resort city popular with foreign tourists and a long‑time CJNG stronghold, thick black smoke rose above the skyline as cartel members set buses and structures alight. A Costco store was reported fully engulfed in flames. Narco blockades — 'narcobloqueos' — were erected on major roads in Tlajomulco, Tapalpa, Ciudad Guzmán, Autlán, and beyond Jalisco into Uruapan in Michoacán and Reynosa in Tamaulipas.

Airlines temporarily halted flights into Puerto Vallarta, forcing aircraft already en route to divert. Pharmacies, convenience stores, and government buildings across the Guadalajara metropolitan area were also targeted as authorities scrambled to regain control of key routes and protect civilians.

The US Embassy issued a formal security alert instructing US citizens in five states — Jalisco, Tamaulipas, parts of Michoacán, Guerrero, and Nuevo León — to shelter in place until further notice. The alert urged people to avoid law enforcement activity, stay off the streets, and keep family informed of their whereabouts. Schools in Jalisco cancelled in‑person classes for Monday, and mass public events were suspended for the rest of Sunday.

The Man They Killed

El Mencho was not just another cartel boss. The US Drug Enforcement Administration had placed a $15 million (£11.9 million) bounty on his head, one of the largest ever offered for a drug lord. On 20 February 2025, Secretary of State Marco Rubio formally designated CJNG as a Foreign Terrorist Organisation and a Specially Designated Global Terrorist under Executive Order 14157, signed by President Trump on his first day back in office. The move placed CJNG alongside al‑Qaeda and ISIS on the US terrorism list and made it unlawful for anyone under US jurisdiction to knowingly provide material support to the group.

His death hands Mexican President Claudia Sheinbaum a significant political win at a time of sustained pressure from Washington to act decisively against trafficking networks. She has, however, previously questioned the so‑called 'kingpin strategy'—the targeting of top cartel leaders—arguing it has often produced fragmentation and fresh waves of bloodshed rather than lasting peace. Sunday offered an immediate, visceral illustration of that concern.

With El Mencho gone, CJNG faces its first true leadership crisis since its founding. Succession disputes and territorial realignment now look almost inevitable, with rival groups already positioning themselves to exploit the vacuum. The violence of 22 February may not be the peak of this crisis. By many assessments, it could be only the opening act.
