An investigation by Trap Aggressor, Süddeutsche Zeitung, NDR, WDR, and Le Monde revealed that the Russian Promtekh group supplies Western-made CNC machines, critical for the defence sector, through the Turkish company Enutek. The authors discovered that Enutek supplied components worth at least $850,000.

Business & Human Rights Resource Centre invited Enutek to respond, but the company did not.
