Mexico has said two US embassy officials killed in a car crash in Chihuahua were not authorised to take part in security operations on Mexican soil, intensifying tensions over American involvement in anti-cartel efforts inside the country. President Claudia Sheinbaum said her government had not approved the operation and stressed that any cooperation with foreign personnel must be authorised at the federal level under Mexican law.
The controversy erupted after a vehicle carrying two US officials and two Mexican state investigators plunged into a ravine during an operation targeting clandestine drug laboratories in Chihuahua. All four people were killed. Mexican authorities have since begun reviewing whether the presence of the US personnel violated national security regulations, amid conflicting accounts about whether they directly participated in the raid or arrived afterwards.
The exact role of the US personnel remains unclear. ABC, citing US officials and sources familiar with the matter, reported that the two embassy staffers were working for the CIA on counternarcotics operations, while AP reported that Mexican authorities have requested a formal explanation and noted that joint ground operations by foreign agents are not permitted without federal approval. The US has not publicly clarified their roles or mission.
The uncertainty is significant because security cooperation with Washington is a highly sensitive issue in Mexico. Sheinbaum has repeatedly stated that intelligence sharing is acceptable, but the presence of foreign “boots on the ground” is not, and the incident has revived longstanding concerns over sovereignty.
For now, the focus is less on the crash itself and more on the nature of the operation that led to it. Until both governments provide clearer details, the case is expected to remain a diplomatic flashpoint in the broader debate over US involvement in Mexico’s fight against drug cartels.
