Estonian authorities uncovered a pro-Kremlin effort in 2022 to form a parallel self-defense unit with Russian GRU support, leading to treason charges and demands for heavy prison sentences.
In a significant hybrid warfare incident in Estonia, investigative authorities revealed that in 2022 pro-Kremlin figures Aivo Peterson and Dmitry Rootsi, supported by the Koos movement, attempted to form a parallel civil defense unit that could take over military functions in a crisis. Prosecutors presented evidence showing Peterson and Rootsi coordinated with the Russian GRU military intelligence for guidance and assistance, aiming to undermine Estonia’s exclusive state defense prerogative. Despite public claims framing the initiative as humanitarian, the prosecution views it as an insidious attempt to create an alternative armed force loyal to Russia. Court proceedings began in November 2023, with final hearings scheduled for June 2025. Estonian prosecutors seek 17 years for Peterson and 13 years for Rootsi on treason charges. This case underscores persistent Russian efforts to destabilize Estonia through political subversion and espionage, coinciding with Estonia’s broader military strengthening near its Russian border.
Confidence: High
The article explicitly details pro-Kremlin actors working with Russian GRU intelligence to form a parallel paramilitary structure in Estonia, constituting hostile Russian hybrid warfare activity, with no mention of defensive measures by Estonia in this context.
