Mexico seeks clarity on U.S. role after fatal Chihuahua crash tied to drug-lab raid

Mexican President Claudia Sheinbaum demanded explanations about what U.S. and Mexican officials were doing in Chihuahua after a car crash that killed four people — two Mexican investigators and two U.S. embassy instructors — following a clandestine drug-lab raid. She stressed that there are no land or air joint operations with foreign entities without federal authorization and raised sovereignty concerns as U.S.-Mexico security debates continue. While officials initially offered sparse details and later some backtracking, the incident underscores ongoing questions about the extent of U.S. involvement and collaboration in Mexican security efforts.
