The Russian missiles sought out targets from the Lviv region in western Ukraine near Poland to Kharkiv in northeast Ukraine bordering Russia. The state energy company Ukrenergo reported emergency power outages in six regions. It often shuts down production during attacks as a precaution.

Ukrainian officials say Russia has launched a major ballistic and cruise missile attack on regions across Ukraine.

Russia launched a new barrage of missiles and drones at Ukraine on Wednesday, targeting gas infrastructure and other energy facilities in western regions in the latest strike on the country's hobbled power system as it approaches mid-winter.

Ukrainian President Volodymyr Zelenskyy warned allies that the defense of his nation is a litmus test for broader Western resolve.

The barrage appeared to be one of the largest recent assaults in Ukraine’s campaign to damage Russia’s war machine on its home territory.

Ukrainian forces used missiles and drones on Tuesday to target sensitive military and energy sites across Russia.

Ukraine struck Russian regions with a major drone and missile attack overnight, damaging at least two factories and forcing schools to close in a major southern Russian city, according to Russian officials and media.
