Russian forces attacking Zaporizhzhia nuclear power plant in Ukraine: Report.

Russian forces are battling for control of Ukraine’s largest nuclear power plant, according to the Associated Press and Reuters.

In a video posted on Telegram, Andriy Tuz, a spokesperson for the Zaporizhzhia Nuclear Power Plant, accused Russia of shelling the facility, which provides a quarter of Ukraine’s electricity.

“We demand that they stop the heavy weapons fire,” Tuz said, the Associated Press reported. “There is a real threat of nuclear danger in the biggest atomic energy station in Europe.”

The mayor of nearby Energodar, some 420 miles southeast of Kyiv, said the plant itself was on fire, Reuters reported.

A video live stream from the plant, which is the largest in Europe, showed at least one building in flames, as well as intermittent explosions — setting off car alarms in the parking lot — tracer rounds, and a column of armored vehicles outside.

In a statement earlier on Thursday, the head of the International Atomic Energy Agency, Rafael Mariano Grossi, had urged combatants to refrain from fighting near Ukraine’s largest power plant after receiving a letter from local authorities warning that Russian infantry was approaching.
