Mexico wants to know if cartel members are fighting in Ukraine to gain drone knowledge
The Mexican government has launched an investigation into the possible participation of members of Mexican drug cartels in the war in Ukraine. The reason is a video circulating on social media, in which men fighting in the Ukrainian army mention the names of two of the best-known Mexican cartels.
According to President Sheinbaum, her government will "try to find out how Mexicans, in this case persons who may belong to a criminal group, became involved in an armed conflict in Europe." The men could "have been recruited by a private company participating in such conflicts, by an army, or by a government," she says.
Sinaloa and Jalisco cartel
In the video, a group of armed men is seen in a forest. According to the man filming, they are returning from a mission. Another man says that the person filming is part of La Chapiza. That is the faction of the Sinaloa cartel led by the sons of drug lord Joaquín 'El Chapo' Guzmán. He then also chants the name of the Jalisco cartel.
Since the summer of 2025, several investigative platforms have reported that the Mexican intelligence service warned Ukraine that cartel members had signed up for the International Legion of the Ukrainian army. Volunteers from other countries can register there to fight against Russia. But until now, no videos had actually surfaced of cartel members at the Ukrainian front.
Special drones
Cartels would mainly send people to Ukraine to train them in the use of so-called first-person view drones (FPV drones). In this, the drone operator sees live images from the drone's camera, making it seem as if they are flying along themselves.
In Mexico, criminal organizations increasingly use such drones to smuggle drugs or to bombard rival territories with explosives attached to these drones. For example, the Jalisco cartel even has its own unit dedicated to the use of drones, investigative platform InSight Crime reported last year.
Since the war in Ukraine, the number of attacks with explosive drones in Mexico has increased: besides rival groups, government buildings and police patrols have also been targeted.
It is estimated that at least 120 drone attacks were carried out in Mexico last year. Hundreds of people died as a result. In the state of Michoacán, chemicals are even attached to explosives on drones, as local police showed to NOS.
Mexican agents told this last year about the weapons used:
At the border, human smugglers use drones to monitor patrols of the U.S. border guards before groups of migrants are guided through irregular tunnels and other border crossings. Drones are also used there to fly doses of the addictive painkiller fentanyl into the U.S.
Last Friday, the U.S. government announced a total drone ban at the border with Mexico to combat this human and drug smuggling.
Strategy from Ukraine?
Mexican authorities have invested heavily in recent years in technology to bring drones down, for example with jammers. Cartels seem to anticipate this by using drones with fiber optic cables, a strategy that appears to have been copied one-to-one from Ukraine.
Earlier this month, fifteen FPV drones along with fifteen rolls of fiber optic cables were seized in the state of Sinaloa. Drones with fiber optic cables had never been found in Mexico before.
The possible participation of Mexican cartel members is a boon for Russia. The Russian intelligence service SVR claimed yesterday on Telegram that the U.S. is now investigating whether there are links between Ukrainian and Mexican drug cartels. Russia states that at least eighty Mexicans have been identified gaining combat experience with the Ukrainian forces.
Ukraine has not responded to the reports about Mexicans allegedly fighting on the Ukrainian side.
