Ukraine's president Volodymyr Zelensky has accused the Kremlin of resorting to "energy terrorism" as Russian troops make few gains on the battlefield. He said 4.5 million people were without power following Russian attacks on its energy network.

The statement comes as Russia has carried out large-scale missile and drone attacks on Ukrainian power facilities in recent weeks.
