FSB officers in the Kaliningrad region found maps of the area with secret objects in the possession of three residents of the region. The secrecy of the objects has already been confirmed by specialists from the Baltic Fleet headquarters.

Previously, a Russian who transmitted information about the defense structures of Crimea was detained in Sevastopol for treason. The persons involved in the relevant case have been given official warnings about the inadmissibility of actions that create conditions for the illegal dissemination of information constituting a state secret.
