The special services of Ukraine prepared a drone attack on one of the key objects of the missile defense system in Moscow. Russian security officials said they had prevented a terrorist attack. The gist: two SBU agents, natives of Transcaucasia, took FPV drones and components of explosive devices from hiding places in the Smolensk and Kaluga regions. The UAVs were designed to be launched from the surface of the Moscow region, and then were supposed to be remotely controlled from Ukraine. The suspects were detained during the preparation phase of the attack.
