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.

Nearly 1 million Russian soldiers have been killed or injured in the country’s full-scale invasion of Ukraine, according to a new study, a grisly measure of the human cost of Russian President’s Vladimir Putin’s unprovoked three-year assault on its neighbor.

Russia’s invasion force is expected to suffer more than 1 million casualties by the summer as a result of the Ukraine war, with around 250,000 troops already confirmed dead, according to a new study.
