Russia launched an intense missile and drone barrage at the Ukrainian capital Kyiv in the early hours of Friday, killing four people, Ukrainian President Volodymyr Zelenskiy said, as powerful explosions reverberated across the country.

Russia launched a massive drone and missile barrage across Ukraine in a major retaliatory strike, days after Kyiv damaged key Russian bombers.

Neither Russia nor Ukraine has a clear path to victory. The Ukrainian drone attack last week and the Russian air raids on Friday don't change that.
