The United States government issued a security alert for Mexicali on Tuesday, August 25, prompting the suspension of U.S. government activities in the city and official travel by American personnel to the Baja California capital.

The U.S. Consulate General in Tijuana advised American citizens in Mexicali to avoid government buildings, remain aware of their surroundings and seek shelter if an incident occurs. The alert did not publicly identify the specific nature of the threat or the facilities that could potentially be targeted.

Reportedly linked to “Los Rusos”.

Journalist Luis Chaparro reported that sources allegedly linked to the U.S. Drug Enforcement Administration (DEA) in San Diego said the alert may be connected to an intercepted phone call involving suspected members of the criminal group known as “Los Rusos.”

According to the report, the individuals allegedly discussed possible attacks against Municipal Police facilities and installations belonging to Mexico’s Attorney General’s Office (FGR) in Mexicali.

However, the DEA has not publicly confirmed the existence of the intercepted call or that it was the specific reason behind the U.S. security alert. The information should therefore be considered an unconfirmed report attributed to intelligence sources rather than an officially established fact.

Mexican authorities say there is no confirmed imminent threat.

President Claudia Sheinbaum said Tuesday that the U.S. warning could be related to the possible presence or activity of a criminal group in Mexicali. She added, however, that the Mexican government does not have information confirming a specific threat to the population.

Mexico’s federal Security Cabinet also said that, so far, authorities have not identified evidence confirming an imminent threat to residents.

Despite that assessment, authorities in Baja California increased preventive operations, patrols and surveillance throughout Mexicali, with participation from state, federal and municipal agencies.

Recent fentanyl seizure raises additional context.

The security alert comes shortly after a major anti-drug operation in Mexicali.
On August 20, Mexican authorities seized approximately 120 kilograms of fentanyl pills, equivalent to an estimated four million doses, at a property that federal authorities linked to “Los Rusos.”

The operation was carried out using information provided by the DEA and involved several Mexican law enforcement agencies.

Although both incidents involve the same criminal organization and there is a recent history of cooperation between Mexican and U.S. authorities, there is currently no official confirmation that the fentanyl seizure is directly connected to Tuesday’s security alert.

Security measures remain in place. As the U.S. warning remains in effect, Mexican authorities continue to maintain a heightened security presence across Mexicali.


The U.S. advisory is primarily directed at American citizens and government personnel, while Mexican authorities have emphasized that there is currently no confirmed information indicating an imminent threat to the general population.
