MEXICO CITY (NPA): The United States Mission in Mexico issued a security alert on February 22, 2026, advising U.S. citizens to shelter in place due to ongoing security operations, road blockages, and related criminal activity. The mission stated: “U.S. citizens in the affected locations should shelter in place until further notice.”
The alert directed all U.S. government staff at Consulate General Tijuana, as well as personnel in Guerrero, Michoacán, and Quintana Roo, to remain sheltered. Staff at Consulate General Monterrey were instructed to stay within the Monterrey metropolitan area. While airports remain open, roadblocks have disrupted airline operations, leading to cancellations of domestic and international flights in Guadalajara and Puerto Vallarta. Taxi and rideshare services in Puerto Vallarta have been suspended, and several businesses have temporarily closed.
The mission urged U.S. nationals in Mexico to minimize movement, remain in residences or hotels, avoid areas of law enforcement activity, stay vigilant, monitor local media, and call 911 in case of emergencies.
The alert follows the killing of Nemesio Rubén Oseguera Cervantes, known as El Mencho, leader of the Jalisco New Generation Cartel (CJNG), during a military operation in Jalisco state. His death has triggered violent reprisals, including vehicle burnings, highway blockages, and unrest in Guadalajara and Puerto Vallarta. Authorities warn that further escalations are likely as Mexico confronts the power vacuum left by one of its most notorious cartel leaders.
