Members of Mexican and Colombian criminal cartels are reportedly enlisting in Ukraine's International Legion (a unit of the Ukrainian armed forces made up of foreign volunteers) and have been filmed fighting there, according to Al Jazeera. The reports say they are seeking hands-on experience with first-person-view (FPV) drones, which cartels increasingly use. The accounts raise concern that criminal networks are using the war in Ukraine as a training ground, though the claims rest on reports and footage that have not been independently verified here.
