Russia Detains Polish Agents in Kaliningrad Espionage Case

The Federal Security Service of Russia announced Wednesday that it identified and localized a Polish intelligence agent network operating in the Kaliningrad Region. The agency reported that the network collected data on Russian military personnel, military facilities, and regional policies regarding migration, economics, and society.

Russian authorities detained two agents linked to the military intelligence service of the Ministry of National Defense of Poland and the Internal Security Agency of Poland. Espionage cases have been opened against both individuals. As part of the operation, the security service issued warnings against treason and espionage to three Russian citizens and seven Polish citizens.

The agency further stated that 14 Polish citizens had their Russian visas canceled in 2026, while six others were barred from entering the country due to alleged complicity with Polish special services.
