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 gist: two SBU agents - natives of Transcaucasia - took FPV drones and bomb components 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 detained during the preparation phase for the attack.
