At least 74 people have died in Mexico following a major security operation that killed cartel leader Nemesio Oseguera Cervantes, widely known as “El Mencho.” The violence included the deaths of 25 National Guard officers and triggered widespread unrest across multiple states.
Mexican authorities said the situation was brought under control by Monday, though the clashes have raised fresh concerns about security ahead of the 2026 FIFA World Cup, which Mexico will co-host.
Operation in Jalisco Turns Deadly
Government forces attempted to arrest Oseguera in the western state of Jalisco on Sunday. According to officials, the cartel leader was injured during the operation and later died while being transported to Mexico City.
His death sparked immediate retaliation from suspected members of the Jalisco New Generation Cartel (CJNG).
Security Minister Omar García Harfuch confirmed that at least 74 people were killed in the clashes, including 25 National Guard personnel.
Cartel Retaliation Across Multiple States
Following the news of Oseguera’s death, cartel members reportedly set fire to vehicles, blocked highways, and launched attacks on banks, petrol stations, and shops in several regions.
The coordinated violence caused temporary chaos and road closures before federal forces restored order.
President Claudia Sheinbaum said Monday that calm had returned.
“Mexico is calm,” Sheinbaum said, adding that roadblocks were cleared and daily activities had resumed.
US Intelligence Support
The White House confirmed that the United States provided intelligence support for the operation. Press Secretary Karoline Leavitt described Oseguera as a top target for both governments due to his alleged role in fentanyl trafficking into the US.
However, President Sheinbaum emphasized that only Mexican forces carried out the on-the-ground operation.
World Cup Security Concerns
The violence has renewed scrutiny over Mexico’s readiness as a co-host of the 2026 FIFA World Cup. A total of 13 matches are scheduled to be played in Mexico City, Guadalajara, and Monterrey, with the remainder in the United States and Canada.
Authorities have not indicated any changes to tournament preparations.
