Ukrainian forces have wiped out dozens of Russian military aircraft, including nuclear bombers, in a massive drone attack on President Vladimir Putin’s air bases deep inside the country, Kyiv sources are claiming. The mission carried out by Ukraine’s Security Service (SBU) using first-person-view (FPV) drones hit 41 Russian heavy bombers at four separate airfields thousands of miles from Ukraine, a security source told the Kyiv Independent on Sunday.
