The second straight day of shelling near the Zaporizhzhia nuclear power plant in Ukraine has fueled concerns in the international community.

Ukraine's nuclear power company Energoatom says an area near a storage facility for spent nuclear fuel came under attack on Saturday.

It says the shelling wounded one employee and damaged radiation monitors nearby.

The shelling followed a similar attack on the previous day near the plant, which is one of Europe's largest.

Ukraine and Russia blame each other.

Ukrainian President Volodymyr Zelenskyy said in a video posted online on Sunday, "There is no such nation in the world that can feel safe when a terrorist state fires at a nuclear plant."

He said, "if something irreparable happens, no one will stop the wind that will spread the radioactive contamination." He also said a principled response of the international community to Russian attacks on the nuclear power plant is needed right now.

Russia's state-run news agency reported Russia's view that Ukraine carried out the attacks.

European Council President Charles Michel tweeted that he and Zelenskyy discussed the situation. He said the plant's safety is of the highest concern.

On Monday, UN Secretary-General Antonio Guterres told reporters in Japan, "Any attack to the nuclear plant is a suicidal thing." He expressed his hope that those attacks will end, and the International Atomic Energy Agency "will be able to have access to the plant and exercise its mandated competencies."
