Ukraine's largest energy provider, DTEK, said hundreds of Russian drones and missiles targeted the electricity network Saturday, damaging two thermal power plants and key high-voltage substations.

Damage to those substations forced operators to reduce output at nuclear power plants, leading to a significant loss of available electricity in Ukraine.

Ukraine gets about 70 percent of its electricity from nuclear power.

In his nightly address Saturday, President Volodymyr Zelenskyy

said Russia continues to attack in massive strikes that are contrary to ongoing diplomatic work to end the war.

This is a level of attack that no terrorist in the world has ever allowed itself, said Zelensky.

Russia, he said, must feel the response of the entire world.
