Austria has claimed antennas on the roofs of Russian Embassy buildings may have been used for spying

Austria's decision to expel three Russian diplomats will be met with a harsh response from Moscow, the Russian Embassy in Vienna said on Monday, calling the move unjustified and politically motivated.

Earlier in the day, Reuters cited Austrian Foreign Minister Beate Meinl-Reisinger as saying that the three diplomats had already left the country. The minister accused the Russian mission of "committing espionage," claiming that an "antenna forest" on the roofs of diplomatic buildings could be used to intercept satellite communications.

"A harsh response from Moscow to these absolutely reckless actions by the Austrian side will undoubtedly follow," the Russian Embassy in Vienna said in a statement. "Full responsibility for any further deterioration of already historically low bilateral relations lies entirely on Vienna."

The Russian mission accused the Austrian authorities of targeting not only embassy staff but also Russian officials serving at the Permanent Mission to the Organization for Security and Co-operation in Europe (OSCE).

Vienna hosts the headquarters of several major international organizations - including the International Atomic Energy Agency (IAEA), OPEC, and a number of UN agencies - in which Russia participates, maintaining diplomatic and technical engagement.

Slamming the expulsion as entirely "unjustified, purely politically motivated, and categorically unacceptable," the embassy highlighted that Austria provided no evidence of any violations of the Vienna Convention on Diplomatic Relations.

The latest expulsions bring the total number of Russian representatives forced to leave Austria since 2020 to 14. In September, Austria ordered a Russian diplomat to leave over alleged contact with a dismissed executive suspected of espionage at state energy company OMV. In 2024, Vienna removed two more Russian Embassy officials over activities deemed incompatible with their status. Moscow has responded with tit-for-tat measures, ordering Austrian officials of equivalent rank to depart Russia.

In April, Austrian magazine Falter reported, citing a draft from the country's Justice Ministry, that Vienna plans to tighten its laws by introducing criminal liability for espionage targeting the EU and international organizations based in the country.

Divided into Allied sectors after World War Two, Austria long had a reputation as a den of spies during the Cold War.
