Mexican authorities have deployed thousands of additional troops across the country after a surge of violence followed the death of cartel leader Nemesio Oseguera Cervantes, widely known as “El Mencho.”
Security officials said the unrest spread to at least 20 states after the head of the Jalisco New Generation Cartel (CJNG) died Sunday while in military custody. According to Defence Secretary Ricardo Trevilla, at least 2,500 extra soldiers were rushed to western Mexico, with reports indicating overall deployments may have exceeded 10,000 personnel nationwide.
Authorities said Oseguera Cervantes was captured by Mexican special forces in Jalisco state after intelligence led troops to a meeting with a romantic partner. He was seriously wounded during a firefight between his security team and commandos and later died while being transported to Mexico City.
In the aftermath, cartel members launched coordinated attacks in multiple regions, burning vehicles, scattering road spikes and targeting businesses. Security Secretary Omar García Harfuch reported that at least 25 National Guard members have died in the violence, along with a prison guard, a prosecutor’s office employee and dozens of suspected cartel operatives.
President Claudia Sheinbaum praised the military operation and sought to reassure the public, stating that authorities are working in close coordination to restore stability. Officials say major road blockades have largely been cleared, though damage to banks and local businesses has been reported.
Security analysts note that the aggressive response underscores the CJNG’s operational reach and the risks that often follow the removal of high-profile cartel leaders. The coming weeks, experts say, will test whether federal forces can prevent further retaliatory violence and maintain control in affected regions.
