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.

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

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.

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.

President Volodymyr Zelensky of Ukraine said air defenses had shot down at least 30 missiles from a “massive” barrage that had targeted gas and energy facilities.

The Ukrainian Air Force and monitoring agencies are reporting a "massive missile attack" on Ukraine. Missiles, including Kalibr, Kh-22, and Kh-101, were launched from 7 Tu-22M3 bombers, 6 Tu-95MS bombers,

Moscow said on Tuesday that Ukraine had fired six U.S.-made ATACMS ballistic missiles, six UK-made Storm Shadow cruise missiles and at least 146 drones into Russia in an attack that it said would not go unanswered.

Initial social media posts from local authorities and numerous eyewitnesses indicate that western Ukraine was the primary target of the attack, with missiles seen flying over central and southern regions of the country and the Carpathian Mountains toward Khmelnytskyi,
