Poland's Internal Security Agency detained a Russian national on 7 August 2026 in Warsaw who was preparing to assassinate a dual US-Ukrainian citizen on orders from Russian intelligence services. This is the first known assassination attempt of a US citizen on Russian orders on NATO territory. Polish Prime Minister Donald Tusk stated the target was considered inconvenient by Putin's regime. The incident is part of Russia's ongoing hybrid warfare against Western European states supporting Ukraine. Polish authorities are increasing preventive measures against future similar threats. The arrest follows the lethal shooting of Russian artist Semyon Skrepetsky in Poland in June 2026, a case linked to Kremlin provocations.
