A court in Estonia has convicted a former military member and his father of espionage for Russia.

Ex-defense force member Deniss Metsavas, 38, and his father Pyotr Volin, 65, were suspected of treason and placed in custody by a court in Tallinn in September. Metsavas was suspected of passing state secrets and classified information to Russia’s military GRU intelligence agency for over 10 years.
