Multiple Ukrainian regions experienced power outages in freezing winter conditions Tuesday after Russia carried out a deadly large-scale attack with drones and missiles, authorities said.

Neighboring Poland scrambled jets to protect its airspace during the strikes, Poland's military said in a post on X.

"Russia once again is attacking our energy infrastructure. As a result, emergency power outages have been introduced in a number of Ukrainian regions," the country's Energy Ministry said on Telegram.

Fires broke out in several regions as a result of the "massive missile and drone attack," Ukraine's power operator Ukrenergo said, as temperatures dipped towards freezing in most of the country.

One person was killed in the western region of Khmelnytsky and another was killed in Kyiv, local authorities said.
