Mexico City A wave of violent clashes erupted across several Mexican states after security forces conducted a major operation against Nemesio Rubén Oseguera Cervantes, widely known as “El Mencho,” the leader of the powerful Jalisco New Generation Cartel (CJNG) and one of Mexico’s most wanted criminals. The confrontation has claimed the lives of at least 25 Mexican National Guard soldiers, officials confirmed.
The deadly violence unfolded following the military raid in the town of Tapalpa, in Jalisco state, where troops engaged cartel gunmen in intense firefights. Oseguera was fatally wounded during the operation and later died while being transported to medical care, according to the Mexican Defense Ministry.
Violence Erupts After Operation
More than 250 roadblocks were reported across at least 20 states as cartel members retaliated, blocking highways with burning vehicles and attacking security forces. Schools, courts and public transit were temporarily shut down in some regions, including in Guadalajara, Jalisco’s capital, where daily life ground to a halt amid growing unrest.
President Claudia Sheinbaum urged citizens to stay calm and avoid confrontation, while authorities worked to restore order and reinforce security deployments in affected areas.
Operation Marks a Significant Moment
Oseguera, aged 59 and one of the most feared leaders in Mexico’s long‑running drug war, had a US$15 million bounty on his head and was a key target for Mexican and international law enforcement agencies for years. His cartel is notorious for drug trafficking, extortion and the use of heavy weaponry including armored vehicles and rockets.
The operation against him involved elite military and intelligence units, and the United States provided intelligence support, reflecting cooperative pressure to curb drug trafficking, especially fentanyl shipments into the U.S.
Heavy Toll on Security Forces and Wider Impact
In stark numbers, authorities reported that 25 National Guard members, a prison guard, a state prosecutor’s agent, and an unidentified woman were killed in multiple violent encounters following El Mencho’s death. Around 30 cartel suspects were also killed in clashes across Jalisco and neighboring Michoacán.
The violence prompted travel advisories from foreign governments and intensified fears among residents and tourists alike, particularly in popular destinations such as Puerto Vallarta and Guadalajara where cities were plunged into disruption.
What Comes Next?
Experts warn that while the death of one leader may be seen as a tactical success, it does not automatically dismantle the cartel’s complex network. Power struggles, splinter groups and further confrontations could follow as rival factions and security forces contest control in the wake of El Mencho’s demise.
For now, Mexico faces a critical period of uncertainty, with authorities racing to prevent further bloodshed and protect communities from escalating cartel violence that has long plagued the nation.
