Violence has erupted across the Mexican state of Jalisco after security forces reportedly killed Nemesio “El Mencho” Oseguera Cervantes, the leader of the powerful Jalisco New Generation Cartel (CJNG), triggering widespread unrest in popular tourist areas including Puerto Vallarta and Guadalajara. The federal army’s operation killed the cartel boss on February 22, 2026, and immediately sparked coordinated attacks by cartel members across major cities, with burning vehicles, roadblocks and gunfire reported in several locations.

The death of El Mencho marks a major blow to one of Mexico’s most notorious criminal organizations but has also led to immediate retaliation and instability, disrupting travel and raising safety concerns for residents and international visitors alike. Authorities continue to work to restore order, and travelers are being urged to follow official guidance and avoid non-essential movement in affected areas.
