Mexican President Claudia Sheinbaum says the warning, based on U.S. intelligence, involves a possible criminal group; officials report no confirmed imminent threat.
CALEXICO —
The U.S. government issued a security alert Monday night for Mexicali, the Baja California state capital just across the border from Calexico in Imperial County, and temporarily suspended consular activities there because of what officials described only as a “potential threat.” The notice did not specify the nature of the threat or identify its intended target.
The alert urged American citizens in the area to avoid government buildings, to seek shelter if an incident occurs, and to remain alert to their surroundings. U.S. officials offered no further public detail on the source or credibility of the threat, leaving residents on both sides of the border with limited information beyond the advisory itself.
Mexican President Claudia Sheinbaum addressed the alert directly during her Tuesday morning press conference, confirming that Mexican authorities had been notified but downplaying the immediacy of any danger. “There was an alert about the possibility of a criminal group,” Sheinbaum said, adding that the report was based on information provided by U.S. intelligence agencies.
Later Tuesday, Sheinbaum’s security cabinet issued a statement saying authorities “have not identified any elements confirming a specific or imminent risk to the population,” though it noted that surveillance and patrols in Mexicali had been increased as a precautionary measure. Mexican and U.S. authorities separately confirmed that Mexican security forces, working from information supplied by the U.S. Drug Enforcement Administration, carried out an operation that seized drugs and weapons from a criminal group known as “Los Rusos” in the hours following the alert.
Mexicali, a city of more than one million residents, sits at the center of one of the busiest transborder regions on the California-Baja California line, tied closely to Calexico through commercial traffic, family ties and daily cross-border commuting. That interdependence meant the alert rippled quickly through Imperial County communities on the U.S. side, even though officials reported no disruption to normal border crossing operations.
The uncertainty surrounding the alert’s specifics has generated anxiety among residents with family on the Mexican side of the border. Border-area residents interviewed by regional outlets described a tense morning trying to reach relatives in Mexicali before confirming they were safe, with one Arizona resident whose father lives in the city calling the guidance “very vague on both sides — from both the Mexican government and the United States government,” noting only that residents had been told to avoid government buildings and unnecessary border crossings.
By Tuesday afternoon, the city of Mexicali remained calm, with no reported incidents tied to the alert. Ports of entry along the Calexico-Mexicali crossing continued normal operations throughout the day, according to local reporting, even as the underlying threat that prompted the advisory remained unexplained to the public.
The episode adds to a string of security-related disruptions along the California-Baja California border this year, and comes amid heightened binational law enforcement cooperation targeting organized crime groups operating in the region. For Imperial County, whose economy depends heavily on cross-border trade and daily commuter traffic through Calexico, the alert is a reminder of how quickly an unexplained security notice from Washington can unsettle a border community that otherwise functions as a single, tightly linked metropolitan area straddling two countries.
The rapid follow-up operation against Los Rusos, carried out with DEA-supplied intelligence within hours of the alert, suggests U.S. and Mexican authorities may have already had the group under active surveillance before Monday night’s advisory went out. That timeline has done little to clarify, for residents on either side of the line, whether the original threat has now been neutralized or whether the seizure addressed only part of a larger concern that prompted the suspension of consular services in the first place.
