Mexico investigates video said to show cartel members fighting in Ukraine

Mexico is investigating a widely shared video in which suspected mercenaries can be heard chanting drug cartel slogans while fighting in the war in Ukraine. The investigation was reported by the international news outlet Al Jazeera on 9 October 2026.

The video has gone viral, meaning it has spread rapidly across social media. The men in it are believed to be mercenaries, people who fight for payment rather than as soldiers of a state's army. According to the headline of the report, the footage is said to show Mexican cartel members fighting on Ukraine's side.

What is known

The source states only that Mexico is looking into the recording and that cartel slogans can be heard in it. It does not say which Mexican agency is leading the inquiry, which cartel the men might belong to, when and where the footage was filmed, or whether its authenticity has been confirmed.

It also does not say whether the men's identities have been established. The wording "suspected mercenaries" and "said to show" indicates that the content of the video has not yet been verified.

Why it matters

The investigation shows that Mexican authorities are paying attention to the possible involvement of Mexican nationals, or people linked to criminal groups, in a foreign armed conflict. More details about the origin of the video and the progress of the inquiry would allow a clearer assessment.
