Germany expels Russian military attaché following espionage investigation in Berlin
On 22 January 2026, it emerged that Germany had expelled the deputy Russian military attaché in Berlin on espionage grounds. The decision followed an investigation that identified activities incompatible with diplomatic status. The move was taken amid heightened sensitivity over security issues connected to defence and arms production. German authorities treated the case as part of a broader counter-intelligence response. The expulsion was confirmed after judicial steps were initiated domestically.
Arrest of German citizen linked to Russian military intelligence triggers diplomatic response
The expulsion was prompted by the arrest of a German citizen of Ukrainian origin, Ilona Wiener, who is suspected of acting as an agent for Russia’s military intelligence. According to investigators, she maintained contact with the expelled attaché. She is alleged to have collected information on the locations of German arms manufacturers, drone testing activities and planned deliveries of unmanned systems to Ukraine. The case details were outlined in the report on Germany’s expulsion of a Russian military attaché over espionage allegations embedded within coverage of the investigation. Authorities also established that the suspect held a Russian passport in addition to German citizenship.
Intelligence gathering extended to political events and covert networking activities
Investigators further allege that the suspect gathered information on participants in various political events across Germany. She is accused of assisting her Russian handler in establishing covert contacts using assumed identities. These activities suggest an effort to map networks beyond the defence sector. The information is considered relevant to influence operations as well as intelligence collection. Additional details circulated via a message outlining the investigation and related arrests during the same period.
Case highlights intensified counter-intelligence focus amid Ukraine-related security concerns
German prosecutors have indicated that the investigation centres on the protection of sensitive military information linked to support for Ukraine and the domestic defence industry. Germany’s role as a major supplier of military assistance places it under sustained intelligence interest. The case forms part of a wider pattern of scrutiny directed at suspected foreign intelligence activity within the country. Authorities continue to assess potential security implications while pursuing the judicial process.
