U.S. CIA Agent Killed During Mexican Anti-Drug Operation
"Unaware of Agent's Involvement in Advance," Says Mexican Government
State Attorney General Resigns... Tensions Rise Between U.S. and Mexico
There have been reports that tensions are escalating between Mexico and the United States following the death of a U.S. Central Intelligence Agency (CIA) agent in Mexico.
According to Yonhap News on April 28 (local time), citing major international news outlets, Mexican President Claudia Sheinbaum sent a diplomatic letter to the United States demanding measures to prevent a recurrence after a U.S. agent participated in a drug crackdown operation in Chihuahua State without prior authorization.
At a press conference, President Sheinbaum stated, "The federal government was not aware of their involvement in the operation in advance. We hope this remains an exceptional case," and emphasized, "The Mexican Constitution and National Security Law must be strictly observed, and the U.S. side has also agreed to this."
Previously, on April 19 in Chihuahua State, two Americans, believed to be CIA agents, and two Mexican investigative officials died in a car rollover accident. It was found that they had participated in a raid on a drug manufacturing facility without federal government approval. Controversy arose as it was reported that one of the deceased Americans had entered the country as a tourist.
Cesar Jauregui, then Attorney General of Chihuahua State and the official in charge of the case, initially denied the direct involvement of U.S. CIA agents right after the incident. However, he later admitted inconsistencies in his explanation and ultimately resigned. In a statement, he acknowledged omissions and inconsistencies in the initial briefing and said, "I hope my resignation will help restore public trust."
Currently, major Mexican cartels are known not only for distributing South American cocaine, but also for being involved in the production and supply of synthetic drugs such as fentanyl.
The Mexican government has maintained a positive stance on sharing information about drug cartels, but has opposed foreign agents or military personnel directly conducting operations on Mexican soil, citing this as an infringement of sovereignty. On the other hand, U.S. President Donald Trump has insisted that U.S. military power should be expanded to respond to Mexican cartels. According to Yonhap News, the Trump Administration also warned that if Mexico's response was deemed insufficient, the United States could take independent action.
As a result, anti-drug cooperation between the two countries has balanced precariously between information sharing and sovereignty concerns. This issue has also been linked to the Trump Administration's hardline stance toward Mexico. Earlier this year, President Trump mentioned the possibility of ground attacks against cartels, while President Sheinbaum stated, "U.S. military intervention is unacceptable."
