El Mencho, Leader of CJNG, Killed in Mexico Military Operation – Escalating Violence Follows

Mexico is facing a national security crisis following the death of Nemesio Oseguera Cervantes, known as “El Mencho,” the leader of the powerful Jalisco Modern Generation Cartel (CJNG). El Mencho was killed during a military operation in Tapalpa, Jalisco, on February 22, 2026, triggering a wave of violence across multiple states.

Operation and Confirmation of Death

The Mexican Secretariat of National Defense (Sedena) confirmed that El Mencho died during a confrontation between military personnel and CJNG members. Infobae reports that the operation involved intelligence work, collaboration with the National Intelligence Center, and the Public Ministry of the Federation (FEMDO). Forces utilized various aircraft from the Air Force and the Immediate Reaction Special Force of the National Guard.

During the operation, four CJNG members were killed at the scene, and three others died en route to a Mexico City hospital due to the severity of their injuries. El Mencho was among those who succumbed to his injuries during transport. Authorities have initiated forensic activities to confirm his identity. Two additional cartel members were arrested, and a significant cache of weaponry, including rocket launchers capable of downing aircraft and destroying armored vehicles, was seized.

Cartel Response: Widespread Violence and Disruption

In response to the operation, the CJNG has launched a campaign of violence, including shootouts, vehicle fires, and road blockades in several regions. The Associated Press reports that Guadalajara International Airport experienced disruptions as cartel members blocked access and opened fire near the terminals. Burned buses were used as barricades on major highways leading into the city.

States of Jalisco, Colima, and Michoacán are experiencing widespread paralysis, with schools and businesses closed. Blockades have extended to Sinaloa (Mazatlán), Puebla, Tamaulipas, Veracruz, Aguascalientes, and Guerrero. Reports indicate attacks on a National Guard base in San Juan de los Lagos and attempted escapes from the Ixtapa prison in Puerto Vallarta. Arson attacks have targeted shops, gas stations, and branches of the state bank Banco del Bienestar.

A no-fly zone has been established within 10 nautical miles of Tapalpa, Jalisco, in connection with the military operation. One UH-60 Black Hawk helicopter sustained damage from gunfire and was forced to return to base.

International Implications

The United States has increased surveillance along its border, anticipating a potential surge in violence or attempts by high-ranking cartel members to flee into the U.S. The U.S. Had previously offered a $15 million reward for information leading to El Mencho’s capture.
