Large areas of Ukraine are suffering blackouts after Russian missiles targeted energy infrastructure.
There is no electricity in the second-largest city of Kharkiv.
Fifteen blasts were reported in Kharkiv, while more than 53,000 households in Odesa were without power.
Ukraine’s energy minister, German Galushchenko, accused Russia of trying to provoke “a large-scale failure of the country’s energy system”.
A power line feeding the Zaporizhzhia nuclear plant had been cut, he added.
Regional head Ivan Fedorov said the power station was “on the verge of a blackout”, adding that seven buildings in the region had been destroyed and 35 others damaged.
President Volodymyr Zelensky said Russia had launched more than 60 Shahed drones and about 90 missiles into Ukraine during the wave of overnight attacks.
At least two people have been reported killed and 14 wounded.
