The vehicle carrying the officials plunged into a ravine, also killing two Mexican investigators from the state investigation agency.

Sheinbaum stated she was unaware of the collaboration between U.S. agents and local authorities, raising questions about potential violations of national sovereignty.

The incident has fueled speculation about the extent of joint drug-fighting operations in the region.

U.S. Embassy officials are working with Mexican counterparts to determine the exact circumstances of the crash.
