Nemesio Oseguera, the leader of one of Mexico's most prominent drug cartels, the Jalisco New Generation Cartel, was killed on the 22nd during a military operation by Mexican authorities in western Jalisco state. This operation was reportedly conducted with intelligence assistance from the U.S. government and resulted in Oseguera's injuries leading to his death during transfer to Mexico City. The operation also saw armed clashes between authorities and cartel members, resulting in at least seven fatalities and the confiscation of military-grade weaponry.

In response to Oseguera's death, violent acts attributed to the cartel have erupted across Mexico, including vehicle arsons and road blockades, particularly in the state capital Guadalajara, a city that had been designated as a host for this summer's FIFA World Cup. Videos circulating on social media depict burned vehicles creating dangerous road conditions, shattering storefront windows, and exacerbating urban chaos in an already tense environment following the news of the cartel leader's demise.

The situation has prompted safety warnings from the US Embassy in Mexico, advising American citizens in Jalisco to find secure locations, and similar alerts were issued by the Canadian government concerning potential gunfire and explosions. The implications of Oseguera’s death extend beyond immediate violence as it raises questions about the stability of the Jalisco cartel and the broader impact on regional security and drug trafficking operations.
