Violence Erupts Across Mexico After Army Kills Notorious Drug Cartel Leader

By: Sunday Ameh

Widespread violence has broken out across Mexico following the killing of notorious drug cartel leader Nemesio Oseguera Cervantes, popularly known as “El Mencho,” during a military operation.

Oseguera, the head of the powerful Jalisco New Generation Cartel (CJNG), was killed on Sunday after Mexican troops engaged cartel members in a shoot-out in the western state of Jalisco, authorities said.

The 59-year-old, regarded as one of the country’s most-wanted drug traffickers, was accused of overseeing large-scale trafficking of fentanyl, methamphetamine and cocaine into the United States, as well as orchestrating violent attacks against government officials.

According to reports, four cartel members were killed at the scene, while three others — including Oseguera — died while being transported to Mexico City for medical treatment.

The operation reportedly received intelligence support from the United States government, which had previously announced a $15 million reward for information leading to the cartel leader’s capture.

Following news of his death, violence erupted across several Mexican states as suspected cartel members blocked highways, set vehicles ablaze and clashed with security forces.

Videos circulating on social media showed fires and heavy smoke across Puerto Vallarta, a major tourist destination on Mexico’s Pacific coast. Local media also reported intense fighting in Tapalpa, a mountainous area within the Sierra Madre region.

The unrest forced airlines to cancel multiple flights, while panic spread at airports in Guadalajara — one of the host cities for the 2026 FIFA World Cup — as passengers rushed for safety amid fears of retaliatory attacks.
Separate footage showed armed men setting fire to vehicles and a petrol station in parts of the city.

Authorities cancelled school activities in several affected states, and both local and foreign governments advised residents to remain indoors as security operations continued.

Mexico’s president, Claudia Sheinbaum, urged citizens to remain calm, stating that normal activities were continuing in most parts of the country despite the unrest.

Security agencies remain on high alert amid concerns of further reprisals from cartel loyalists following the death of the influential crime boss.
