Ukraine's Sabotage Network in Russia Equipped with Drones: CNN

US officials believe Ukraine is behind a network of anti-Putin rebels in Russia, arming them with drones for a series of attacks, including the drone explosion over the Kremlin in May. Ukraine has not claimed any connection to such groups, but is reaping the military benefits. The attacks have been claimed by anti-Putin Russian dissident group the Liberty of Russia Legion, which opposes the invasion of Ukraine. It is unclear who is controlling these groups, but US officials believe Ukraine's military intelligence is involved.
