Mexican President Claudia Sheinbaum demanded an explanation from the United States following a car crash that killed two CIA agents and two Mexican officials during an anti-drug operation in Chihuahua. According to multiple reports, Sheinbaum sent a diplomatic note to the U.S. Embassy requesting information about unauthorized participation of U.S. agents in field operations on Mexican territory.

During her morning press conference, Sheinbaum stated that Mexico's Foreign Relations Ministry sent a letter to U.S. Ambassador Ronald Johnson seeking clarification about the incident. The actions were not part of the agreed security protocol or current bilateral understanding between the two countries, raising concerns related to national sovereignty. She emphasized that Mexico does not accept field participation by any foreign agents in operations and has made this clear to the United States government.

The controversy emerged after a vehicle accident involving U.S. CIA officials and local investigators during an operation targeting clandestine drug laboratories. The president clarified that while Mexico's Defense Ministry participated in the anti-drug operation, it was not informed about the involvement of U.S. agents, describing this as a violation of Mexico's National Security Law.

According to sources familiar with the operation, four CIA agents were involved in the raid, raising questions about the scope of the agency’s activity in Mexico. The agents were dressed in Chihuahua State Investigative Agency uniforms to blend in with Mexican officials. A CIA spokesperson said the agency could not comment.

Conflicting accounts from Mexican and U.S. officials have compounded confusion over who was involved in the anti-drug operation. Chihuahua Attorney General César Jáuregui described the U.S. personnel as part of routine cooperation with local authorities, stating they were carrying out training duties. However, Sheinbaum insisted that any joint collaborations between the local government and the U.S. without federal permission would be a violation of Mexican law.

The incident has reignited debates over the extent of U.S. involvement in Mexican security operations, with President Donald Trump increasing pressure on Mexico to crack down on trafficking groups. Sheinbaum has drawn a firm line against any unilateral U.S. activity inside Mexico, emphasizing that cooperation is limited to intelligence-sharing within a clearly defined framework.

Sheinbaum also mentioned considering possible sanctions against the government of Chihuahua for allowing CIA agents to participate in the operation without federal approval. She acknowledged that while the Mexican army participated in the operation as part of its mandate, it was unaware of the U.S. agents' presence. Security Secretary Omar García Harfuch reiterated that foreign agents have never been in the field with Mexican forces.

Following an investigation ordered by President Claudia Sheinbaum, Mexico's security ministry said that 'neither had formal accreditation to participate in operational activities,' and that federal authorities had not been informed of their presence. The incident comes amid at-times fraught relations between Mexico and the U.S. on a number of issues including counter-narcotics.

Sheinbaum has come under intensifying pressure from U.S. President Donald Trump to crack down on drug trafficking, but has repeatedly declined offers of U.S.-led counter-narcotics operations in the country. She has been adamant that foreign officials can only operate on Mexican soil if given prior clearance by the federal government, and has insisted the Central American nation's sovereignty should not be breached.

Mexico's security ministry said on Saturday that immigration records showed one of the agents had entered the country as a 'visitor,' while the other had travelled on a diplomatic passport. The crash occurred on April 19 when a convoy returning from an operation targeting suspected methamphetamine labs in a remote, mountainous area veered off the road and plunged into a ravine.

In her daily morning press conference, Sheinbaum stated that Mexico requested 'from now on, as has been done, our constitution and national security law should be followed,' adding that the U.S. had indicated its agreement. This statement underscores the sensitivity of U.S.-Mexico relations regarding security cooperation.
