US Suspends Consular Operations in Mexicali After DEA Raid on Cartel Cell Triggers Security Threat

The United States government issued a security alert for the Mexican border city of Mexicali and temporarily suspended consular operations Monday night following a DEA-backed raid on a violent cartel faction, prompting concerns about potential retaliatory attacks.

The notice warned Americans planning to visit the capital of Baja California state, located across the border from Calexico, California, to avoid government buildings and seek shelter in the event of an incident. The US government did not specify the nature of the threat but urged citizens to remain aware of their surroundings.

Mexican President Claudia Sheinbaum confirmed Tuesday that the alert stemmed from information about "the possibility of a criminal group" provided by US agencies. Her security cabinet later said authorities had stepped up surveillance and patrols in Mexicali as a preventative measure, though they had "not identified any elements confirming a specific or imminent risk to the population."

DEA Operation Targets Major Cartel Faction

Mexican and US authorities revealed that Mexican security forces, working with intelligence from the Drug Enforcement Administration, carried out an operation to seize drugs and weapons from Los Rusos, a criminal cell affiliated with the Sinaloa Cartel. The group operates primarily in Mexicali's drug trafficking corridor, distributing fentanyl, methamphetamine, cocaine and heroin from Mexico to the United States.

US Northern Command stated that Mexican authorities worked to "identify, disrupt, and dismantle cartel operations posing a threat to the United States along the U.S.-Mexico border." The operation follows a seizure of 120 kilograms of fentanyl pills on August 20, and media reports citing security sources indicate that radio intercepts revealed Los Rusos members were planning reprisals against police and ministerial agents.

The criminal organization is led by Juan José Ponce Félix, alias "El Ruso," for whom the US Department of State is offering a reward of up to $5 million for information leading to his capture or conviction. According to reports by the Los Angeles Press, the cell has been linked to at least 412 homicides over the past two years as Ponce Félix expands territorial control across the northern Mexicali Valley and northwestern Sonora.

Strategic Border Crossing Under Heightened Security

The security concerns in Mexicali carry significant implications given the city's strategic importance. The Calexico East and Calexico West ports of entry jointly record a historical annual average of approximately 30 million border crossings, including 5.1 million pedestrians, 24.7 million trips in personal vehicles, and approximately 640,000 trucks. Mexicali, with more than 1 million residents, is one of the most populous cities along the Mexican border with close commercial and social ties to its American neighbor.

Baja California Governor Marina del Pilar Ávila said around midnight that Mexican authorities remained active and security operations would be reinforced throughout the state capital. The city remained calm throughout Tuesday.

Part of Broader Security Campaign

The Mexicali operation represents the latest action in an intensifying campaign against organized crime in the region. According to local media reports, Mexican authorities have conducted at least 10 state and federal operations against the Sinaloa Cartel's criminal structure in Mexicali since December 2025.

The crackdown reflects the security approach of President Sheinbaum, who took office on October 1, 2024, and appointed Omar García Harfuch, her former Mexico City security chief, as Secretary of Security and Citizen Protection. During Sheinbaum's tenure as mayor of Mexico City from 2018 to 2023, she and García Harfuch reduced homicides in the capital by half through civilian policing, bolstering investigative capacity, and sharing intelligence with US law enforcement agencies.

The Sheinbaum administration launched Operation Swarm in November 2024, a federal crackdown targeting the crime-politics nexus at the municipal level, which has resulted in approximately 60 arrests across six states, including mayors and security directors.

This is not the first time in 2026 that heightened security operations have prompted US alerts in the region. In February, the US issued widespread security alerts across multiple Mexican states, including Baja California, requiring US citizens to shelter in place and suspending normal consular operations due to major security operations.
