Ukrainian drones and missiles targeted four Russian military airfields across the country on Sunday, destroying some of its nuclear-capable bomber fleet on the ground.

The governors of the Russian regions of Irkutsk and Murmansk confirmed drone attacks in their respective regions.

Videos shared with ABC News by the SBU showed drones attacking Olenya airbase in Murmansk and Belaya airfield in Irkutsk. Both are home to Russian strategic bomber aircraft, including nuclear-capable bombers.
