On February 22 2026 Mexican security forces carried out a large-scale military operation in the state of Jalisco targeting the arrest of El Mencho 59 The operation followed extensive intelligence efforts and was supported by information-sharing and coordination with the United States according to Mexico’s Ministry of Defense. During the operation an armed clash broke out between security forces and cartel members El Mencho was seriously wounded in the exchange of fire He was airlifted to Mexico City for treatment but died from his injuries while being transported. Immediately after his death was announced coordinated and violent unrest erupted across several Mexican states particularly Jalisco Michoacán Guanajuato and Colima. ____ Gunmen linked to the cartel set fire to civilian vehicles and public transportation buses and established flaming barricades along major highways Videos circulating on social media showed thick columns of black smoke rising over multiple cities including Guadalajara. Major roads were shut down due to burning blockades and transportation was disrupted across wide areas. As the security situation deteriorated dozens of flights were canceled to and from several airports including Puerto Vallarta International Airport as a precaution to ensure passenger safety. Thousands of schools were also closed in some affected regions to protect students and staff amid fears that the violence could continue. Mexican President Claudia Sheinbaum called on citizens to remain calm and avoid spreading rumors stressing that the government is working in full coordination between the army and federal and local security forces to restore order. Authorities stated that the operation against El Mencho was part of broader efforts to combat organized crime and weaken the influence of cartels that control large areas of the country. Following the escalation the United States and Canada issued travel advisories for their citizens in Mexico urging them to exercise caution avoid affected areas and remain in safe locations. ____ Security experts warned that the death of a high-profile cartel leader like El Mencho does not necessarily mean an end to violence Instead it could trigger a new phase of internal power struggles within the cartel or clashes with rival criminal organizations.

As authorities attempt to contain the unrest and reestablish control the country remains on edge amid concerns that further escalation could unfold in the coming days.
