Accusations fly between Ukraine and Russia over Europe's largest nuclear power plant. And the world frets.

Kyiv and Moscow continued to accuse each other of shelling Europe's largest nuclear power plant, stoking international fears of a catastrophe on the continent.

On Friday, Nikolai Patrushev, the secretary of Russia's Security Council, accused the United States of encouraging Ukrainian attacks on the Zaporizhzhia nuclear power plant in southern Ukraine. The facility has been controlled by Russian forces since shortly after the invasion began on Feb. 24.

"In case of a technological disaster, its consequences will be felt in every corner of the world," Patrushev said. "Washington, London and their accomplices will bear full responsibility for that."
