The head of the United Nations’ nuclear watchdog expressed growing anxiety about the safety of the Zaporizhzhia Nuclear Power Plant, after the governor of the Russia-occupied area ordered the evacuation of a town where most plant staff live amid ongoing attacks in the area.

The plant is near the front lines of fighting, and Ukrainian authorities on Sunday said that a 72-year-old woman was killed and three others were wounded when Russian forces fired more than 30 shells at Nikopol, a Ukrainian-held town neighboring the plant.
