The FSB announced the arrest of "Polish spies" in the Kaliningrad region.
Russian intelligence services claim to have arrested two people who allegedly worked for Polish intelligence. According to the FSB, they gathered information about military facilities, military personnel and the situation in the area.
Seven other Polish citizens and three Russians received warnings. Poles are also banned from entering Russia.
There is no independent confirmation of the allegations. It is possible that the next high-profile "explosion of the spies" will become the reason for the renewal of the exchange fund.
