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.

Russia’s military on Tuesday said it would retaliate against Ukraine after Kyiv attacked Russian regions by firing six US-made ATACMS ballistic missiles, six UK-made Storm Shadow cruise missiles and launching one of the biggest drone attacks to date.

The scale of the assault on Wednesday was not immediately clear, but Ukraine’s energy minister called it “massive.”

Russia launched dozens of missiles and drones at the Ukrainian energy sector, Kyiv said Wednesday, ramping up a months-long bombing campaign at a precarious moment of the war for Ukraine.The barrage came just one day after Kyiv said it had carried out its largest aerial attack of the war on Russian army factories and energy hubs hundreds of kilometres from the front line.

The Kremlin accused Ukraine on Monday of conducting "energy terrorism" and posing a danger to Europe's energy security, after an attempted drone attack on part of a major gas pipeline
