Mexico is grappling with widespread violence following the death of its most-wanted drug lord, Nemesio "El Mencho" Oseguera, leader of the notorious Jalisco New Generation Cartel (CJNG). Oseguera, 59, was fatally wounded during a shootout with soldiers in Tapalpa, Jalisco state, on Sunday, and subsequently died while being airlifted to Mexico City, as confirmed by the army.

News of Oseguera's demise triggered immediate and severe retaliation from cartel members across Mexico. In an unprecedented display of force, cartel operatives blocked roads in 20 states, set fire to numerous vehicles, and torched businesses. The ensuing clashes resulted in heavy casualties among Mexican security forces; Security Secretary Omar Garcia Harfuch reported that 25 National Guard members, a prison guard, and a member of the state prosecutor's office were killed. Additionally, 30 suspected members of Oseguera's criminal organization died in the violence. The special forces operation to capture Oseguera also led to the deaths of eight suspected cartel gunmen and injuries to three soldiers, according to Defense Secretary Ricardo Trevilla.

The impact of the violence was deeply felt by the civilian population. Fearful residents in affected areas went into hiding, while tourists sought refuge in their hotels and resorts. In Jalisco's state capital, Guadalajara, streets were deserted on Monday, with schools, stores, pharmacies, and gas stations remaining shut. Public transportation was suspended, and all large crowd events were canceled. Maria Medina, a gas station worker whose workplace was torched, recounted being told to evacuate by gunmen, fearing abduction. The unrest extended to the resort city of Puerto Vallarta and spread to neighboring Michoacan state, where the CJNG has been engaged in fierce battles with rival criminal groups.

Oseguera, who had a $15 million US bounty on his head, was considered one of the last drug lords operating in the brutal style of figures like Joaquin "El Chapo" Guzman and Ismael "El Mayo" Zambada. With his son, Ruben "El Menchito" Oseguera Gonzalez, already convicted in the US, experts like David Mora of the Crisis Group have warned that Oseguera's death could create a dangerous power vacuum, potentially leading to violent realignments within the CJNG.

The international community quickly reacted to the escalating crisis. Britain, Canada, and the United States issued travel warnings, with Washington urging its citizens in Mexico to "shelter in place." Australia advised its citizens to "exercise a degree of caution." Dozens of US and Canadian flights to Mexico were canceled amidst the unrest. White House Press Secretary Karoline Leavitt confirmed that Washington provided "intelligence support" for the operation, though Mexican President Claudia Sheinbaum adamantly stated that no US forces participated directly in the capture raid.

Mexico's government responded by dispatching 2,500 troops to Jalisco, a state preparing to host four World Cup soccer games later this summer. The army reported that two suspected cartel members were arrested during the operation, and a cache of weapons, including rocket launchers capable of Downing airplanes and destroying armored vehicles, was seized.

The CJNG, founded in 2009 by Oseguera, has evolved into one of Mexico's most violent and powerful drug cartels, surpassing even the Sinaloa cartel in its ruthlessness. The US has classified CJNG as a terrorist organization, accusing it of extensive trafficking of cocaine, heroin, methamphetamine, and fentanyl into the United States. US Deputy Secretary of State Christopher Landau welcomed the operation, calling Oseguera "one of the bloodiest and most ruthless drug kingpins." The raid coincided with ongoing pressure from US President Donald Trump on Mexico to intensify its efforts against drug trafficking, with Trump having previously threatened tariffs on Mexican exports for insufficient action.
