MOSCOW, Nov 11 (Reuters) - Russia's Federal Security Service (FSB) said on Wednesday it has arrested two people described as agents of the Polish secret services for gathering information on military facilities in Russia's western Kaliningrad region, Interfax reported.
Interfax also cited the FSB as saying it warned seven Polish citizens and three Russian nationals due to what it said were their contacts with the Polish security services.
The Kaliningrad region is a Russian exclave on the Baltic Sea that borders Poland and Lithuania. It has occasionally been a flashpoint between Russia and the European Union and NATO.
