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.

Ukraine fired six US-made ATACMS ballistic missiles, six British Storm Shadow cruise missiles and at least 146 drones into Russia in a mass attack, says Moscow. It threatened retaliation against the air strikes.

Russia launched scores of missiles and drones at Ukraine on Wednesday, targeting gas infrastructure and other energy facilities in western regions in a new barrage against the struggling power system in the depths of winter.

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

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

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.

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.
