KYIV, Ukraine (AP) -- Russian forces shelled a city close to Europe's biggest nuclear power plant Thursday, reinforcing the U.N. nuclear chief's fears that the situation around the facility is "grave and dangerous."

Dnipropetrovsk's regional governor says Russia fired 60 rockets at Nikopol, across the Dnieper River from the Zaporizhzhia nuclear plant.

Russian troops seized the plant early in the war.

Some 50 residential buildings were damaged in the city.

Rafael Grossi, head of the International Atomic Energy Agency, said earlier this week that the situation is becoming more perilous at the Zaporizhzhia plant.

Ukrainian authorities say shelling of a town in the eastern Donetsk region left at least eight people dead. And the mayor of the separatist-held city of Donetsk says six were killed there.
