Mexico says it is probing whether the United States violated Mexican sovereignty during the 2024 capture of drug lord Ismael “El Mayo” Zambada. Mexican officials state the matter is under investigation, amid conflicting public accounts about whether U.S. agencies participated in the operation.

According to reports, the inquiry follows actions by the U.S. Federal Bureau of Investigation (FBI), which has displayed a plane that authorities say was used in the transport of Zambada to the United States. The display is said to contradict an earlier statement attributed to the U.S. Embassy, which indicated that no American agency was involved in the operation.

While the U.S. side has not been described in these reports as acknowledging a violation, the Mexican investigation focuses on whether the circumstances of the 2024 capture and transfer were carried out in a way that infringed Mexico’s authority over its territory. The reports describe the issue as one involving allegations of misinformation and competing claims about the operation’s participants.
