The killing of drug cartel leader Nemesio Oseguera Cervantes, known as 'El Mencho', has sparked widespread violence in Mexico, leading to the postponement of several football matches and heightening concerns over security for the 2026 FIFA World Cup. Guadalajara, scheduled to host four group-stage games, has seen roadblocks, burning vehicles, and a red alert declaration. Experts warn of potential instability, though some note cartels' economic interests in a peaceful tournament.
On Sunday, Mexican military forces killed Nemesio Oseguera Cervantes, alias 'El Mencho', the leader of the Jalisco New Generation Cartel (CJNG), in an operation in Tapalpa, Jalisco state. The cartel, estimated to have tens of thousands of members and operations in 21 of Mexico's 32 states, responded with gun shootouts, roadblocks, and arson attacks across at least a dozen regions, including Guadalajara. Videos showed gunmen patrolling streets and smoke over cities, with at least 25 National Guard officers killed within 24 hours.
The violence prompted a code red security situation in Jalisco, where public transportation was suspended, in-person classes halted, and mass events banned on Sunday and Monday. Guadalajara, home to over a million people and set to host four World Cup matches at Estadio Akron—including South Korea against a playoff winner on June 11, Mexico versus South Korea on June 18, and Uruguay against Spain on June 26—activated a red alert protocol, closing bars and restaurants.
Football was directly affected: the women's Clásico Nacional between Chivas de Guadalajara and Club América was postponed, as was the men's Liga MX match between Querétaro and Juárez, plus two second-division games. The Mexican Football Federation cancelled a friendly between Mexico and Iceland scheduled for Wednesday at Corregidora Stadium in Querétaro.
Experts offered mixed views. Javier Eskauriatza, assistant professor of criminal law at the University of Nottingham, noted, "When you push down on the cartels you do get pushback - the danger is that it can be very difficult to manage a security situation that spirals out of control." He added that cartels have an economic stake in the World Cup, owning businesses that benefit from tourism. However, Monica Serrano Carreto, professor at El Colegio de México, warned of a "risk that this leads to a new period of instability," citing the cartel's access to advanced weapons.
The US government advised citizens in Jalisco to shelter indoors, while Canada cancelled flights to Puerto Vallarta airport. The UK urged extreme caution. FIFA has not commented, but its Mexico executive director, Jurgen Mainka, stated in November 2025 that security protocols with the government ensure safety for fans, teams, and officials. Mexican President Claudia Sheinbaum emphasized coordinated security efforts with host cities.
Despite the unrest, the Mexican Open tennis tournament in Acapulco proceeds as normal. The violence underscores long-standing concerns, recalling incidents like the 2011 gun battle outside Santos Laguna's stadium and the 2019 Culiacanazo.
