Swedish authorities are investigating the Russian Orthodox Church located in Västerås, Sweden, over suspicions of espionage activities. The Church of the Holy Mother of God of Kazan, affiliated with the Moscow Patriarchate, is situated approximately 300 meters from a strategically important military airport linked to NATO. Journalistic investigations, including reports by France 24, suggest that the church may be used as a platform for spying on behalf of Russia. The location's proximity to the airport and the church's architectural features have raised concerns among Swedish intelligence services. This case is part of a broader pattern where Russian Orthodox churches in Europe are suspected of serving dual roles as religious institutions and intelligence hubs. The investigation also reflects growing apprehension in Sweden about hybrid warfare tactics potentially employed by Russia. Discussions have emerged about the possibility of closing the Russian Orthodox Church in Sweden due to national security threats.
