A video released by AP shows the destruction inside the Zaporizhzhia nuclear power plant, the largest such facility in Europe.

The plant was captured by the Russian military on Friday, according to Ukrainian authorities and later confirmed by Russian Defense Ministry spokesman Igor Konashenkov.

Earlier on Friday, a fire broke out in a training building outside the plant, which the mayor of the nearby town of Energodar claimed was "the result of continuous enemy shelling of buildings and units" at the nuclear power plant.

The Russian Defense Ministry refuted the claim, saying that the fire was the result of a provocation by Kyiv aimed at accusing Russia of creating a hotbed of radioactive contamination.

"As of 7:00 a.m. (local time) on March 5, 2022, the radiation level in the territory of Zaporizhzhia region remains unchanged and does not pose a threat to the life and health of the population," the head of the Zaporizhzhia regional administration, Olexandr Starukh, said Saturday on Facebook.

Russian forces have now seized two Ukrainian nuclear power plants and are advancing toward a third, Ukraine's president told U.S. senators in a call on Saturday.
