A Russian drone attack caused significant damage to the radiation shelter of the Chernobyl nuclear power plant overnight, Ukrainian President Volodymyr Zelenskyy said on Friday.
Chernobyl was the site of the world's worst civil nuclear catastrophe when one of its four reactors exploded in 1986. That reactor is now enveloped by a protective shelter, known as a sarcophagus, to contain the lingering radiation.
The Russian drone struck the shelter of the destroyed power unit at the plant, causing a fire that has since been extinguished, he said.
"As of now, radiation levels have not increased and are being constantly monitored," Zelenskyy said, adding that an initial assessment had found significant damage.
"The only country in the world that attacks such sites, occupies nuclear power plants, and wages war without any regard for the consequences is today’s Russia," he said.
The Pentagon said on Wednesday that US strikes 10 days ago had degraded Iran's nuclear programme by up to two years, suggesting the US military operation likely achieved its goals despite a far more cautious initial assessment that leaked to the public.
Five people were injured, including a seven-year-old boy and a nine-year-old girl, in a Russian attack on the southern Ukraine port of Odesa overnight, Ukrainian authorities said on Thursday.
Four people died, 38 were missing and 23 survived after a ferry carrying 65 people sank near the Indonesian island of Bali, the country's Search and Rescue agency said on Thursday.
