Mexican President Claudia Sheinbaum has ordered an investigation into the role played by two US officials in a counter-narcotics operation in the northern state of Chihuahua. The two died alongside two Mexican officials when their car crashed while returning from an operation to destroy illegal drug labs, as confirmed by Chihuahua officials.

Sheinbaum expressed that neither she nor senior members of the federal security team had been informed about any joint US-Mexican operations. The Mexican leader insists that foreign officials can only operate on Mexican soil with federal clearance, asserting that Mexico's sovereignty must be respected.

Amid pressure from US President Donald Trump to enhance efforts against drug trafficking, Sheinbaum stated that while intelligence-sharing occurs, there cannot be joint operations without prior approval. She emphasized the necessity for understanding the circumstances surrounding the incident to evaluate possible legal implications further.

On Sunday morning, it was reported that the vehicle carrying the US nationals and members of the Chihuahua State Investigation Agency skidded off the road and fell into a ravine, resulting in an explosion. According to US Ambassador Ronald Johnson, the deceased were identified as 'US embassy personnel'. Additionally, Chihuahua State Attorney-General César Jáuregui elaborated that they were engaged in training activities related to the agency’s general exchanges with US authorities.

With both US and Mexican officials now investigating, key questions regarding the legality and conduct of such operations remain critical to the discussions moving forward.}
