Ukrenergo, Ukraine's state-run energy operator, has said Thursday’s Russian missile strikes resulted in “substantial damage” to the power grid.
“The recovery of the power grid becomes harder, and lasts longer, after every Russian attack,” the company said in a statement posted to Facebook.
It noted that Ukraine had now suffered 13 missile attacks and 15 drone attacks on its energy facilities.
Some background: Russia launched 70 missiles at Ukraine on Thursday, 47 of which were intercepted, the Ukrainian Armed Forces said in its daily operational update on Facebook.
Moscow's forces also carried out 44 airstrikes, including 18 using Iranian-made Shahed-136 drones. All self-detonating drones were shot down, the Ukrainian Armed Forces said.
Earlier, Ukrainian Prime Minister Denys Shmyhal said the main targets were energy facilities.
