"Ukraine’s security services launched a covert strike on five air bases across Russia. More than 100 attack drones smuggled into Russia in plywood cabins on trucks driven by unsuspecting Russians destroyed bombers sitting on tarmacs as far away as the Belaya air base in Siberia, around 3,000 miles from Kyiv. According to Ukrainian government sources, the strikes took out about one-third of Russia’s long-range bomber force and cost Moscow roughly $7 billion."
