Following violent unrest sparked by the reported killing of Nemesio Oseguera Cervantes, also known as El Mencho, the United States issued a fresh advisory urging its citizens to shelter in place. Authorities said domestic and international flights were canceled in Guadalajara and Puerto Vallarta, while taxis and ride-share services were suspended in Puerto Vallarta. Several businesses also shut down operations.

The advisory applies to Americans in Jalisco, including Puerto Vallarta, Chapala, and Guadalajara, as well as in Tamaulipas, parts of Michoacán, Guerrero, and Nuevo León. U.S. government personnel at the Consulate General in Tijuana and staff in Guerrero, Michoacán, and Quintana Roo were also instructed to remain indoors.

Citizens were advised to avoid areas with heavy law enforcement activity, stay alert, limit unnecessary movement, monitor local media, follow official instructions, avoid crowds, and contact emergency services by dialing 911 if needed. They were also encouraged to keep family and friends informed of their safety.

Mexican authorities confirmed that El Mencho, head of the Jalisco New Generation Cartel, died after a military-led operation in Tapalpa, Jalisco. During the operation, cartel members exchanged gunfire with security forces, leaving four suspected gang members dead at the scene. Oseguera and two others were critically injured and later died while being transported to Mexico City. Three Mexican military personnel were also wounded. The operation led to widespread violence across Jalisco, with suspected criminal groups burning buses, blocking roads, and clashing with authorities, according to Governor Pablo Lemus Navarro. The unrest later spread to other states, including Michoacán and Guanajuato.

Oseguera, a former police officer, had led the cartel’s expansion into one of Mexico’s most powerful criminal organizations. He was wanted by U.S. authorities, who had offered a reward of up to 15 million dollars for information leading to his capture. In 2022, the U.S. Justice Department charged him with overseeing fentanyl production and trafficking into the United States.
