4.5 million Ukrainians without power - Zelenskiy

STORY: Russia's attacks in the past few weeks on Ukrainian energy and water supplies have hit civilians hard as winter approaches, the Kyiv government says.

Temperatures can fall far below freezing in winter, now just weeks away.

Russia invaded Ukraine on February 24. The war now in its ninth month has killed thousands, displaced millions and destroyed towns and cities. Moscow describes its actions as a special military operation.
