Mexico’s most wanted drug lord, Nemesio Rubén Oseguera Cervantes, better known as “El Mencho”, was killed in a military operation that unleashed coordinated violence across several states, paralysed transport networks and prompted security advisories from the United States and Canada. The Mexican army said the 59-year-old leader of the Jalisco New Generation Cartel was wounded during a clash with soldiers in Tapalpa, Jalisco, and died while being flown to Mexico City.
The operation marks one of the most consequential blows to organised crime in Mexico since the arrests of Joaquín Guzmán, known as “El Chapo”, and Ismael Zambada García, co-founders of the Sinaloa cartel. Within hours of the announcement, cartel gunmen set vehicles ablaze, blocked highways and clashed with security forces in what authorities described as retaliatory violence spreading across at least five states.
What happened in Tapalpa
According to Mexico’s Secretariat of National Defence, security forces from multiple federal branches carried out the operation in the town of Tapalpa in western Jalisco. The army said Oseguera was wounded in a firefight and later died during an air transfer to Mexico City.Officials stated that six suspected cartel gunmen were killed during the operation, while three soldiers were wounded and taken to hospital in the capital. Two suspects were arrested. Authorities also seized a cache of weapons, including rocket launchers capable of taking down aircraft and destroying armoured vehicles.An AP report cited a federal official who confirmed that the killing occurred during a military operation in Jalisco. The official spoke on condition of anonymity as they were not authorised to comment publicly.The United States had offered a reward of up to 15 million dollars for information leading to Oseguera’s arrest. In February, the Trump administration designated the cartel as a foreign terrorist organisation.
US and Canada issue travel advisories
Following the unrest, the US State Department urged American citizens in several regions to take shelter. In a statement posted on social media, it said: “Mexico: Due to ongoing security operations and related road blockages and criminal activity, U.S. citizens in the following locations should shelter in place until further notice: Jalisco State (including Puerto Vallarta, Chapala, and Guadalajara), Tamaulipas State (including Reynosa and other municipalities), areas of Michoacan State, Guerrero State, and Nuevo Leon State.”The advisory recommended avoiding areas around law enforcement activity, minimising unnecessary movements, monitoring local media, following instructions from authorities and contacting emergency services by dialling 911 if required.Canada’s Ministry of Foreign Affairs said it was closely monitoring the “serious and rapidly evolving security situation” in Jalisco, particularly in Guadalajara and Puerto Vallarta. Canadian citizens were advised to adhere to shelter-in-place orders in affected areas.
Wave of retaliatory violence
Soon after news of the raid emerged, gunmen blocked more than 20 roads in western Jalisco using burning cars and trucks. The unrest spread beyond Tapalpa to Guadalajara and the tourist hub of Puerto Vallarta, and later to neighbouring states including Michoacan and Guanajuato.In Guanajuato, authorities reported fires at pharmacies and convenience stores. “No injuries have been reported, but there has been property damage,” the state’s Security and Peace Secretariat said, adding that a joint operation involving the army, National Guard and municipal police had been deployed.Residents described scenes of panic. Maria Medina, who works at a gas station that was set on fire, said armed men ordered people to leave. “I thought they were going to kidnap us. I ran to a taco stand to take cover with the people there,” she told AFP.Jalisco Governor Pablo Lemus Navarro urged residents to remain indoors and said public transport services would be suspended “until the situation is under control.” He warned that the violence had spread to at least five states and advised people to avoid travelling on highways.In Guadalajara, streets were largely deserted as shops, pharmacies and petrol stations shut their doors.
Sporting events and public life disrupted
The security situation forced authorities to cancel public events and sporting fixtures. Jalisco, which is scheduled to host four matches of the 2026 World Cup this summer, suspended all large gatherings on Sunday and cancelled in-person classes on Monday.Multiple football matches were also postponed, including fixtures from the Clausura tournament of Mexico’s Liga MX, women’s league games and an international friendly between Mexico and Iceland.Airlines were affected as well. US and Canadian carriers cancelled dozens of flights to Mexico amid concerns over the violence. Air Canada suspended flights to Puerto Vallarta, a popular resort destination on the Pacific coast.
International reaction and political pressure
US Deputy Secretary of State Christopher Landau welcomed the killing and described Oseguera as “one of the bloodiest and most ruthless drug kingpins.”“This is a great development for Mexico, the US, Latin America, and the world,” he added.The raid comes amid renewed pressure from US President Donald Trump on Mexico to curb the flow of drugs, especially fentanyl, into the United States. Trump has repeatedly threatened tariffs on Mexican exports, arguing that Mexico has not done enough to combat trafficking.The US Justice Department charged Oseguera in 2022 with leading efforts to manufacture and distribute fentanyl for importation into the United States. An indictment alleged that his organisation operated in several Mexican states, including Jalisco, Colima and Veracruz, with a broader national presence.
The rise of CJNG
Formed in 2009, the Jalisco New Generation Cartel grew rapidly into one of Mexico’s most violent and powerful criminal organisations. According to US authorities, it was responsible for trafficking cocaine, heroin, methamphetamine and fentanyl into the United States.Oseguera, a former police officer, led the group as it expanded its territorial control and influence, frequently engaging in brazen confrontations with security forces. The US Drug Enforcement Administration described CJNG as among the “most powerful and ruthless criminal organisations” operating in Mexico.Mexican President Claudia Sheinbaum called for calm following Sunday’s events and said the federal government was coordinating with state authorities to restore order.While the killing of El Mencho represents a milestone in Mexico’s fight against organised crime, the swift and violent backlash underlines the enduring capacity of cartels to disrupt public life and challenge the state. Security forces remain deployed across affected regions as authorities attempt to stabilise the situation.
