The President of Mexico, Claudia Sheinbaum, informed that her government sent a diplomatic note to the US to demand answers for the participation of US agents in an anti-drug operation in the state of Chihuahua, where two US officials and two Mexicans were killed, in a case that could imply a violation of national sovereignty.
“This has to be clarified. Foreign Affairs made a letter to the U.S. ambassador so that he could provide all the information,” Sheinbaum said at a press conference, noting that a message has been sent to the U.S. ambassador, Ronald Johnson, to explain what happened.

The controversy erupted after the U.S. Embassy confirmed the death of two U.S. officials and two Chihuahua investigators in a road accident in the sierra.
After actions against clandestine laboratories in this northern Mexican state on the U.S. border.
Sheinbaum detailed that the letter points out that this fact “is not part of the security protocol we have agreed (with the U.S.) and the understanding we have with them”.
“It is a matter of national security and sovereignty, that is why what happened is not minor,” he insisted.
The president insisted that federal authorities were unaware of the participation of two foreign agents in field work.
This may be a violation of national security.
“There was no knowledge of it.”
“We have reviewed whether Foreign Affairs or National Defense or the Ministry of Security were informed, and there was no report of the participation of these people,” he said.

In addition, he stressed that no state government can establish security collaboration with foreign authorities outside federal channels.
He warned that the actions of agents from other countries in national territory are regulated by the Constitution and the National Security Law.
“It has to be clear to both the U.S. and state governments that collaboration must occur within the framework of understanding and the law,” he said.
Initially, the Chihuahua state prosecutor stated that the agents were returning from the operation.
But he later clarified that the Americans were not directly involved in the seizure of the laboratory used by drug traffickers and that they were conducting training.
Controversy grew when The Washington Post reported that the two Americans allegedly belonged to the CIA.
And they had intelligently supported an operation against drug trafficking, in a context of increased security pressure from Washington on Mexico and political sensitivity to national sovereignty.
