MEXICO CITY, April 27 (Reuters) - Mexican President Claudia ⁠Sheinbaum ⁠said on Monday that ⁠her government told the United States, in a diplomatic ​note, that the unauthorized presence of U.S. officials at an anti-narcotics operation in ‌the northern state of Chihuahua ‌should not be repeated.

The incident came to light after two U.S. ⁠officials, along ⁠with two Mexican officials, were killed in a car crash ​on April 19 after the operation. Sheinbaum has said the federal government was not aware of the participation of the U.S. officials, who sources told Reuters ​were CIA officers.

"What we told (the U.S.) was that the federal government didn't ⁠know ⁠about the involvement of these ⁠people (in ​the operation) and we hope that it's an exception," Sheinbaum said in her ​daily morning press ⁠conference. Mexico requested that "from now on, as has been done, our constitution and national security law should be followed," Sheinbaum added, saying that the U.S. had indicated its agreement.

On Saturday, Mexico's security cabinet said in a statement ⁠that the U.S. officials lacked formal accreditation to participate in security activities ⁠in Mexico and that one of them had entered the country as a tourist.
