“Any attack on a nuclear plant is something suicidal,” Mr Guterres said in Japan, where he attended the Hiroshima Peace Memorial Ceremony to mark the 77th anniversary of the world’s first atomic bomb. Ukraine said fresh Russian shelling on Saturday damaged three radiation sensors and injured a worker at the Zaporizhia power plant, the second strike in consecutive days at the site. Ukrainian President Volodymyr Zelensky has accused Russia of practicing “nuclear terrorism” that warrants more international sanctions, this time on Moscow’s nuclear sector. “There is no such nation in the world that could feel safe when a terrorist state shoots up a nuclear plant,” Mr Zelensky said on Sunday. Russian forces seized the factory in southeastern Ukraine in early March, but it is still operated by Ukrainian technicians. Russian authorities in the region said Ukrainian forces hit the site with multiple rocket launchers, destroying administrative buildings and an area near a storage facility. The Russian embassy in Washington also issued a statement reporting the damage. “Ukrainian nationalists launched an artillery strike on the territory of this object on August 5. Two high-voltage power lines and a water pipeline were damaged as a result of the shelling. Only thanks to the effective and timely actions of the Russian military in covering the nuclear facility, its critical infrastructure was not affected,” the embassy said.
