Banks burn, vehicles ablaze, flights grounded: Why El Mencho killing plunged Mexico into turmoil

Mexico City: Mexico witnessed widespread unrest after security forces killed Nemesio Oseguera Cervantes, known as El Mencho, leader of the Jalisco New Generation Cartel (CJNG), in a military operation in Tapalpa, Jalisco.

Within hours of his death, suspected cartel members launched retaliatory actions across multiple states. Gunmen blocked highways using burning vehicles, torched supermarkets and businesses, and clashed with security forces in what authorities described as coordinated reprisals.

Violence spreads across states

The unrest affected Jalisco, Colima, Michoacan, Nayarit, Guanajuato and Tamaulipas. In some areas, armed men reportedly attacked security installations and set up roadblocks along major transport corridors, including the Mexico-Puebla highway.

In Guadalajara, a host city for the upcoming FIFA World Cup, residents were urged to remain indoors. Public transport was suspended in parts of Jalisco, and schools were cancelled in several municipalities.

Authorities in Guanajuato reported dozens of incidents across multiple towns but later stated the situation had stabilised.

Flights grounded and travel advisories issued

Air travel was disrupted as airlines including Air Canada, United Airlines and Aeromexico cancelled services to Puerto Vallarta and Guadalajara. Tourists in Puerto Vallarta were advised to shelter in place as smoke from burning vehicles was seen rising over parts of the city.

The U.S. Department of State issued travel advisories urging American citizens in affected states to remain in safe locations. Canada also released similar warnings for certain regions.

Government response

Mexican authorities said the operation that killed Oseguera was conducted with intelligence support from US agencies. He was injured during the clash and later died while being transported to Mexico City.

President Claudia Sheinbaum acknowledged the violence but stated that most of the country continued normal activities. Security forces were deployed in affected regions to restore order.

Risk of internal power struggle

Security analysts warn that Oseguera’s death could trigger internal disputes within the CJNG, as there is no clearly established successor. Previous arrests and killings of cartel leaders in Mexico have led to similar waves of retaliation and internal conflict.

The situation presents a significant security challenge, particularly with Mexico preparing to host major international sporting events in the coming months. Authorities are expected to intensify operations to prevent further escalation.

For now, several regions remain under heightened security as officials monitor potential further reprisals linked to the cartel’s leadership vacuum.
