Russia says Polish spy network dismantled in Kaliningrad

Russia’s Federal Security Service announced on Thursday that it had uncovered and dismantled a Polish intelligence spy network operating in the Kaliningrad region. The group was reportedly gathering information on Russian military personnel, defense ministry facilities, as well as the region’s social, economic, and migration policies.

According to Russia’s Sputnik news agency, the security service said its operation led to the arrest of two agents linked to Poland’s military intelligence and internal security agency. The pair allegedly collected and transmitted information to Polish authorities.

The Federal Security Service confirmed that criminal cases have been opened against the detainees under Article 276 of the Russian Criminal Code, which pertains to espionage. A court has ordered them to be held in pre-trial detention.

According to Russian Sputnik, the agency issued official warnings to seven Polish citizens and three Russians who had been in contact with Polish intelligence, cautioning them not to engage in acts that may constitute preparation for high treason, secret cooperation with a foreign state, or espionage.

As part of its security measures, the service announced the cancellation of Russian visas for 14 Polish nationals in 2026 and barred six others from entering the country. A long-term entry ban has also been imposed on the Polish citizens involved.
