US Intelligence Helped Mexico Take Down ‘El Mencho’ – Violence Erupts Across 11 States

Mexico is grappling with widespread violence following the death of Nemesio Oseguera Cervantes, known as “El Mencho,” the leader of the Jalisco New Generation Cartel (CJNG). The operation that resulted in his death on Sunday, February 22, 2026, was significantly aided by intelligence gathered by a U.S. Military-led task force, according to officials.

A U.S. Defense official confirmed to Reuters that the Joint Interagency Task Force–Counter Cartel, established in January, played a crucial role in mapping the networks of cartel members on both sides of the U.S.-Mexico border. While the official, speaking anonymously, did not detail the specific information provided, they emphasized that the raid itself was a Mexican military operation. The U.S. Government, however, compiled a detailed package of intelligence regarding “El Mencho” and delivered it to Mexican authorities for execution by their armed forces.

This intelligence included information gathered from U.S. Security forces and intelligence services. Officials stated that Oseguera Cervantes was a top, if not the top, priority target for the United States in Mexico. The Mexican Secretariat of National Defence acknowledged receiving “complementary information” from U.S. Authorities but did not elaborate on the details.

Sheinbaum Calls for “Calm” Amid Disturbances

Mexican President Claudia Sheinbaum responded to the escalating violence with a call for calm, stating that most of the country was experiencing a normal day despite the unrest triggered by El Mencho’s death. “The Secretariat of National Defence reported the operation carried out this morning by federal forces, which led to various blockades and other reactions,” she wrote on X. “There is absolute coordination with governments of all states. we must remain informed and calm.”

Sheinbaum added that her Security Cabinet is providing ongoing updates on the situation through social media, assuring the public that “in most of the national territory, activities are developing with complete normality.” She also expressed her “recognition” to the Secretariat of National Defence, the Army, the National Guard, and the Armed Forces for their role in the operation that eliminated the CJNG leader and six other cartel members.

The Violence Following “El Mencho’s” Death

The operation that killed “El Mencho” sparked a wave of violence that spread across at least 11 Mexican states, including roadblocks, vehicle fires, attacks on businesses, and clashes with security forces. These actions were reportedly carried out by cells linked to the cartel.

In Jalisco, the epicenter of the crisis, authorities reported the arrest of 25 individuals as of 4:00 PM local time, with 11 detained for alleged involvement in violent acts and others for suspected looting. At least 21 roadblocks were reported across various highways in the region. Businesses closed preventatively, and classes were suspended for Monday in all public and private educational institutions at all levels.
