A large Russian drone-and-missile attack has targeted Ukraine’s eastern city of Kharkiv, killing at least three people and injuring 21.

The Ukrainian operation was “grounds for a nuclear attack,” declared Vladmir Solovyov, a firebrand host on Russian state TV, calling for strikes on the Ukrainian presidential office in Kyiv, and beyond.

Trump told German Chancellor Friedrich Merz that Russia and Ukraine were fighting like children in a park and might not want to be pulled apart yet.

Former Rep. Chris Stewart, a former fighter pilot, says the U.S. isn’t prepared for this change in modern warfare.

Ukraine’s security service released footage Wednesday of its attack on Russian war planes at multiple airbases across the country. In the span of a few hours on Sunday, nearly a third of Moscow’s strategic bomber fleet was destroyed or damaged with cheaply made drones sneaked into Russian territory, according to Ukrainian officials.

Russia asked the U.N. nuclear watchdog on Friday to mediate between Moscow and Washington to resolve the question of what to do with U.S. nuclear fuel stored at a Ukrainian power plant controlled by Russian forces.

Russia's military released the statement after Ukrainian officials said Russia had launched an intense missile and drone barrage at Kyiv, the Ukrainian capital, in the early hours of Friday and that three people had been killed.
