Britons in Mexico are advised to stay indoors and avoid non-essential travel due to a surge in violence following the reported death of cartel leader Nemesio Ruben Oseguera Cervantes, also known as ‘El Mencho’. The unrest, which included widespread roadblocks and vehicles set ablaze, has affected tourist areas such as Guadalajara and Puerto Vallarta in Jalisco state, potentially disrupting routes to airports.

Violence Erupts After Key Cartel Leader's Death
The Mexican army announced on Sunday, February 22, that it had killed ‘El Mencho’, a high-profile drug cartel leader and a U.S. Most Wanted fugitive, during a military operation in Tapalpa, Jalisco. The operation reportedly resulted in the deaths of several cartel members and injuries to some army personnel. This action has been framed by Mexican officials as a significant victory against organized crime.

Security Concerns and Travel Disruptions
Following the announcement of ‘El Mencho’s’ death, a wave of violence and unrest was reported across Mexico. Key disruptions included:

Roadblocks: Over 250 blockades were set up in at least 20 Mexican states, with the majority concentrated in Jalisco. While many have since been cleared, some remained active.
Disrupted Travel: Routes to airports were reported as potentially blocked, and several airlines, including U.S. carriers, suspended flights to tourist destinations like Puerto Vallarta, stranding some American tourists.
School Closures: Schools were cancelled in several affected states on Monday.
Official Warnings: The UK’s Foreign Office issued updated travel advice on Monday, February 24, urging British nationals to remain indoors and avoid unnecessary travel. The U.S. embassy in Mexico also advised its citizens to shelter in place across several states.
Conflicting Accounts and Unclear Long-Term Impact
While the Mexican government has presented the operation as a success, the full ramifications for the country’s security landscape remain unclear.

The Military Operation
Official Narrative: The Mexican army reported killing ‘El Mencho’ in Tapalpa, Jalisco, during an operation aimed at his capture. Four cartel members were killed and three injured during this specific operation, with three army personnel also sustaining injuries. The U.S. reportedly provided intelligence that aided the operation.
Circumstances of Death: Reports indicate ‘El Mencho’ was wounded in an operation on Sunday and died while being transported to Mexico City.
The Cartel's Response
Widespread Unrest: The death triggered hours of unrest, including vehicles being set on fire and numerous roadblocks erected across Jalisco and other states.
Disruptive Tactics: The violence appears largely aimed at causing disruption, impacting transportation and daily life.
Expert Analysis and International Pressure
The killing of ‘El Mencho’ occurs within a context of ongoing pressure from the United States for Mexico to more aggressively pursue drug cartels. The U.S. had previously designated his cartel and others as foreign terrorist organizations. This success could be used by the Mexican government to demonstrate results to the U.S., particularly concerning its drug trafficking issues. However, the long-term effect on Mexico’s security landscape is yet to be determined.
Conclusion and Next Steps
The reported death of ‘El Mencho’ has demonstrably led to a significant increase in organized crime-related violence and disruptions across Mexico, prompting international travel advisories. While the immediate operation resulted in the neutralization of a key cartel leader, the subsequent unrest highlights the continued challenges to security.
