The recent killing of Nemesio Rubén Oseguera Cervantes, known as 'El Mencho', the leader of the Jalisco New Generation Cartel (CJNG), by the Mexican army has triggered a significant surge in violence throughout Mexico. Schools have been closed in various states, and both local and international authorities advised their citizens to remain indoors as cartels responded aggressively, blocking roads and incendiary attacks on vehicles. This illustrates the volatile situation that arises from targeting high-profile drug leaders, as it can instigate violent backlash from their organizations.

El Mencho was notorious for overseeing a vast criminal empire involved in the trafficking of fentanyl, methamphetamine, and cocaine, primarily directed towards the US market. His death occurred during a military raid in Jalisco, the very state he controlled, highlighting the challenges the Mexican government faces in bringing violent leaders to justice without inciting further chaos. The CJNG, known for its brutal tactics, immediately responded with coordinated assaults across at least 20 Mexican states, leading to widespread fear and disruption.

President Claudia Sheinbaum has appealed for calm as authorities work to dismantle the numerous roadblocks created by cartel members, with reports indicating that over 250 were established in a short period. The US government has also played a role, providing intelligence support for the military operation that led to El Mencho's demise. This situation emphasizes the ongoing struggle in Mexico against organized crime and the implications for public safety and governance in the face of such retaliatory violence.
