Russia carried out a large-scale missile and drone attack targeting Ukraine’s energy infrastructure across five regions, Ukrainian President Volodymyr Zelensky announced on Tuesday. He said the assault, which occurred on Monday, was the largest of its kind against Ukraine’s power system in nearly four years of war. According to Zelensky, Russia fired more than 70 ballistic and cruise missiles and deployed 450 drones to overwhelm Ukraine’s air defenses. The Ukrainian Air Force reported intercepting only 38 missiles, meaning many struck their intended targets.

The attacks caused significant damage to power plants and infrastructure in Kyiv and other areas. Private energy company DTEK described the assault as the most powerful strike of the year. The offensive came as temperatures dropped to minus 20 degrees Celsius, worsening civilian hardship. Zelensky accused Russia of choosing terror over diplomacy and urged allies to apply maximum pressure on Moscow.

The scale of the strikes and the severe winter conditions suggest prolonged disruptions to Ukraine’s energy supply and increased humanitarian strain.
