Ukraine’s President Volodymyr Zelensky said 4.5 million people were without power following Russian attacks on its energy network.
In recent weeks, Russia has carried out large-scale missile and drone attacks on Ukrainian power facilities.
The strikes come as officials say Russian troops are likely to withdraw from the key southern city of Kherson.
After suffering a series of painful defeats on the battlefield, Russia has stepped up attacks in recent weeks on electricity infrastructure in cities away from the front lines.
In just the last month, a third of the country’s power stations have reportedly been destroyed, according to President Zelensky. END.
