(@seunonoticias/X)Mexican President Claudia Sheinbaum said Wednesday that reports claiming the CIA was involved in a recent targeted assassination outside Mexico City were "fictions the size of the universe." CNN and the New York Times reported Tuesday that the CIA was involved in the targeted car bombing of a mid-level Sinaloa cartel member on March 28. Video captured by the rear dash camera of a vehicle driving on a highway outside of Mexico City showed another vehicle exploding before it crossed a median into oncoming traffic and crashed to a stop. CBC News verified that the video posted to social media by Mexican news outlet SéUno Noticias was authentic and not manipulated by AI, but has not been able to determine who originally recorded it.The explosion left suspected Sinaloa cartel member Francisco "El Playin" Beltran and his driver dead. "Only imagine that there are agents of the CIA operating on our national territory to kill or eliminate someone. Imagine the size of the construction of such a lie in a report of this size," said Sheinbaum, during her regular weekday morning media conference. Mexican President Claudia Sheinbaum said Wednesday that reports claiming the CIA was involved in a recent targeted assassination outside Mexico City were 'fictions the size of the universe.' (Paola Chiomante/Reuters)Mexico's Secretary of Security and Citizen Protection Omar Harfuch immediately denied the reports Tuesday evening in a post on social media platform X. CIA spokesperson Liz Lyons followed Harfuch's post with her own carrying the agency's official denial. "This is false and salacious reporting that serves as nothing more than a [public relations] campaign for the cartels and puts American lives at risk," Lyons wrote.

The federal Attorney General's Office is currently investigating the case. Chihuahua's Governor Maria Eugenia Campos Galván has denied she knew of the U.S. officials involvement in the operation. Reports plausible, security analyst saysDavid Saucedo, a Mexico City security analyst, said the reports of the CIA involvement in a targeted assassination on Mexican soil are plausible given the history of the agency in Latin America.Saucedo said the CIA used the same tactics battling guerilla groups in Colombia during the 1990s. "And to me, it appears to be normal for the Mexican and U.S. authorities to deny this."Una presunta granada detonó dentro de un auto en movimiento en Tecámac y dejó dos muertos.<br>Indagan si el artefacto fue activado tras recoger a “El Payín” en el AIFA. <br><br>Conoce más👇<a href="https://t.co/TRZmVhZnNc">https://t.co/TRZmVhZnNc</a> <a href="https://t.co/2qrHnzBLVV">pic.twitter.com/2qrHnzBLVV</a>—seunonoticiasSaucedo said Beltran, the alleged target in the bombing, was a key figure in the logistics operations of the Sinaloa cartel's drug smuggling operations. He said Beltran was also at one point in charge of regional operations for the criminal organization and was believed to be aligned with the faction loyal to Ismael "El Mayo" Zambada, a one-time leader of the Sinaloa cartel. Probe alleging 'El Chapo' sons fed victims to tigers led to case against top Mexican politician: court docsMexico moved extradition goalposts after U.S. indicted top politician over cartel ties: experts"His assassination signified a major loss for the cartel's operations," said Saucedo. "Surely by now they have already begun to quickly identify the figures who can take over his functions." It's impossible to know why Beltran was targeted in the car bombing without seeing the other pieces of the puzzle in this alleged CIA operation, he said. Questions remain in kidnapping: SheinbaumThe Sinaloa cartel has been fractured by a civil war that has roiled the state of Sinaloa for nearly 20 months. According to Saucedo, it's unclear which side Beltran was on at the time of his death.The conflict exploded after one of the sons of Joaquín "El Chapo" Guzmán Loera, Joaquín Guzmán López, lured Zambada to a meeting in July 2024, kidnapped him and put him on a plane that flew to New Mexico. Guzmán López surrendered to U.S. authorities and handed over Zambada and they both remain in custody. Sheinbaum said during Wednesday's news conference that many questions remain around U.S. law enforcement's role in the kidnapping of Zambada that "unleashed" violence across Sinaloa."For those dedicated to investigating these themes, it would be interesting to review how this situation unfolded," said Sheinbaum, Wednesday.
