El Mencho, killed in a military raid, was confirmed by Mexican officials after a security operation in the western state of Jalisco. The Defence Ministry said Nemesio Oseguera, leader of the Jalisco New Generation Cartel (CJNG), died following a shootout and subsequent air transfer to Mexico City.
According to authorities, Oseguera was seriously injured during the confrontation and later succumbed to his wounds. Officials added that U.S. authorities provided “complementary information” related to the operation.
The raid triggered immediate unrest across several Mexican states. Reports indicated torched vehicles and armed individuals blocking highways, particularly in the north and west of the country.
Videos circulating on social media showed cars ablaze, sending thick smoke into the air. Jalisco Governor Pablo Lemus Navarro urged residents to remain indoors until security forces regained control. The U.S. embassy also advised its citizens to shelter in place.

Security experts warned that Oseguera’s death could spark further violence as factions compete for control. Vanda Felbab-Brown, an expert on organised crime, said such high-profile takedowns often lead to instability.
The CJNG has been linked to the trafficking of cocaine and fentanyl into the United States. Mexican authorities view the operation as a major step in their campaign against organised crime.
Air Canada temporarily suspended operations to Puerto Vallarta, Jalisco, amid the unrest. Authorities continue to monitor the security situation as investigations proceed.
While officials hailed the operation as a strategic victory, analysts caution that the aftermath may test Mexico’s security infrastructure in the coming days.
