Austria has expelled three employees of the Russian embassy in Vienna over allegations of espionage involving surveillance equipment installed on Russian diplomatic properties, marking another escalation in tensions between Moscow and European governments.
The Austrian Foreign Ministry confirmed reports that authorities suspected the three diplomats of using antenna systems mounted on rooftops of the Russian Embassy and another diplomatic compound in Vienna’s Donaustadt district to conduct intelligence-gathering operations. According to reports aired by Austrian broadcaster ORF, the equipment was allegedly capable of intercepting satellite-based communications and data transmissions linked to international organisations operating in the Austrian capital.
Vienna hosts several major international institutions, including the International Atomic Energy Agency, Organization of the Petroleum Exporting Countries, and the Organization for Security and Cooperation in Europe, making the city a highly sensitive location for diplomatic and intelligence activity.
Austrian Foreign Minister Beate Meinl-Reisinger said espionage represented a serious national security concern and stressed that diplomatic immunity could not be used as cover for intelligence operations. She stated that the government had adopted a tougher approach toward foreign spying activities and had made Austria’s position “unequivocally clear” to the Russian side.
According to reports, Austrian authorities summoned the Russian ambassador in April and requested that Moscow waive diplomatic immunity for the three individuals so prosecutors could pursue a formal investigation. Russia reportedly refused, leading Austria to expel the diplomats instead. The individuals have already left the country.
The case reflects a broader deterioration in relations between Russia and European states since the start of the Ukraine war in 2022. Since then, multiple European governments and Russia have engaged in reciprocal expulsions of diplomats accused of espionage or covert operations. Austria, despite maintaining a long-standing policy of military neutrality, had initially been more cautious than some Western countries in taking such measures but has gradually hardened its stance.
Austria is also moving to strengthen its espionage laws. Current legislation primarily criminalises foreign spying when Austrian national interests are directly targeted. Proposed legal changes would expand protections to cover international organisations and institutions operating within Austria as well.
The Russian Embassy in Vienna later criticised Austria’s decision as “outrageous” and warned of consequences for bilateral relations. In a statement posted on Telegram, Moscow said Austria would bear responsibility for further damaging ties, which it described as already at a historic low.
The expulsions underline growing concerns across Europe about intelligence operations carried out under diplomatic cover, especially in cities hosting critical international agencies and strategic global institutions.
