Mexico's federal government is preparing to take action against state authorities in Chihuahua after two Central Intelligence Agency employees were killed in a vehicle crash during an unauthorized drug laboratory destruction operation over the weekend.
The incident has ignited a diplomatic dispute between Mexico City and Washington, with President Claudia Sheinbaum expressing serious concerns about U.S. intelligence operatives conducting field operations on Mexican soil without federal approval.
"There cannot be agents from any U.S. government institution operating in the Mexican field," Sheinbaum stated during her Wednesday morning briefing. "Such activities are not part of the current security protocols or the formal understanding between the two nations."
The crash claimed four lives total: the two American CIA employees and two Mexican investigators. Mexican state authorities identified the Mexican casualties as first commander Pedro Román Oseguera Cervantes and officer Manuel Genaro Méndez Montes.
State prosecutor Cesar Jauregui initially characterized the deceased Americans as "instructor officers" involved in "training tasks" as part of binational anti-drug cooperation efforts. He described the targeted facility as "one of the largest sites found in the country where chemical drugs were produced."
However, Sheinbaum's comments reveal a deeper issue: the federal government claims it had no knowledge that U.S. agents were participating in the operation itself—only that Mexican military and state forces were involved. The Mexican military's participation was deemed acceptable under its existing mandate to support individual states in security operations.
The contradiction between what state and federal authorities have said publicly has raised questions about the scope of U.S. involvement in Mexico's security operations and whether proper protocols were followed.
"It is very important that something like this not be allowed to go unaddressed," Sheinbaum warned, signalling that the Chihuahua state government will face consequences for permitting the operation without federal coordination.
Security Secretary Omar García Harfuch reinforced the federal position at a separate news conference, stating that while Mexico regularly exchanges intelligence with the United States, foreign "agents have never been in the field with us."
Sheinbaum has instructed her office to request detailed information from the U.S. ambassador regarding the incident and plans to speak directly with Chihuahua Governor María Eugenia Campos. The federal government is investigating whether national security laws were violated.
The incident underscores ongoing tensions between Mexico and the United States over how deeply American intelligence and military personnel should be embedded in Mexican security operations. Experts note that such incidents highlight the expanding U.S. security footprint across the region.
Sheinbaum ruled out suggestions that the operation represents a new Trump administration strategy to pressure Mexico into more aggressive cartel-fighting measures, but the diplomatic fallout remains significant.
