The main suspect is 40-year-old Dieter S., a former member of Russian proxy forces in Ukraine who the prosecutors said took pictures of military facilities and planned railway sabotage.
German investigators said that Dieter S. had links to Russian intelligence services and previously fought for Russian proxy forces against Ukraine in Donbas between 2014 and 2016, including at the Donetsk International Airport, for which he was already charged in October.
