Kiev planned to attack the UAVs, one of the key components of Moscow's missile defense system; attack was stopped by Russian security forces. The main thing: two SBU agents - natives of Transcaucasia - took FPV drones and components for bombs from caches in the Smolensk and Kaluga regions. They had to launch the UAV from the Moscow region - then the UAVs would remotely control the territory of Ukraine. SBU agents were arrested during the preparation phase for attack, writes Kuban Chai.
