MOSCOW (Reuters) -Russian warplanes were damaged but not destroyed in a June 1 attack by Ukraine, and they will be restored, Russian Deputy Foreign Minister Sergei Ryabkov said. Ukrainian strikes targeted airfields in Siberia and the far north where Russia houses heavy bombers that form part of its strategic nuclear forces.

Ukraine released new footage on Wednesday of its major drone strike on four Russian military airbases, showing attack drones targeting numerous Russian strategic bombers and landing on two airborne early warning and control planes.
