Russia launched a large-scale missile attack on Wednesday, some slamming into energy facilities that caused power losses in several regions of the country, officials said.

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.

NATO member Poland scrambled fighter jets after overnight Russian missile and drone attacks on Ukraine, Warsaw's military said on Wednesday. Newsweek has reached out to Polish authorities and Russia's Defense Ministry for comment via email.
