Violence Erupts in Mexico as U.S. Helps in Killing of Cartel Leader
The Trump administration has admitted to a role in the killing of the cartel leader known as “El Mencho.”

Violence broke out in parts of Mexico on Sunday after government security forces killed Nemesio Rubén Oseguera Cervantes, or “El Mencho,” the country’s most wanted drug kingpin—with “intelligence support” from the United States.
El Mencho was killed in a shootout with security forces in Jalisco. As founder of Cartel Nueva Generacion Jalisco, or CJNG, he was most active in fentanyl, methamphetamine, and cocaine trafficking and put out hits on multiple members of government.
“The United States provided intelligence support to the Mexican government in order to assist with an operation in Talpalpa, Jalisco, Mexico, in which Nemesio ‘El Mencho’ Oseguera Cervantes, an infamous drug lord and leader within the Jalisco New Generation Cartel, was eliminated,” White House press secretary Karoline Leavitt wrote on X. “President Trump has been very clear—the United States will ensure narcoterrorists sending deadly drugs to our homeland are forced to face the wrath of justice they have long deserved.”
The violence was immediate and retaliatory, according to Mexican authorities. There were multiple explosions and reports of gunfire, as billows of smoke appeared in at least 13 different states. Armed cartel members blew up gas stations and set up various blockades with burning cars, and the U.S. Embassy in Mexico issued a security alert as many American tourists remain trapped.

“The fear that remains in society is overwhelming,” a Zitacuaro, Michoacan, resident told Al Jazeera. “That’s when you realise the immense power these organisations have, because they can collapse a city in a matter of minutes.… They have co-opted the leaders who manage transport, and at any moment they can block the entrances and exits of a city.… They can completely paralyze a city’s movement.… All basic services are disrupted: going to hospitals, grocery shopping, ordering food. It becomes total chaos.”
President Claudia Sheinbaum urged her citizens to remain calm in the face of these attacks.
“The Secretariat of National Defense reported on the operation carried out this morning by federal forces, which resulted in various blockades and other reactions. There is absolute coordination with the governments of all states; we must remain informed and calm,” she wrote. “The social media accounts of the Security Cabinet provide permanent updates. In the vast majority of the national territory, activities are proceeding with complete normality.”
While Deputy Secretary of State Chris Landau called El Mencho’s death a “great development for Mexico,” others acknowledged the death of El Mencho—the last of an era of Mexican kingpins that included El Chapo and El Mayo—as a major shift in a conflict that is far from over.
