Ukrainian President Volodymyr Zelenskiy said on Friday that a Russian drone had caused significant damage to the radiation containment shelter at the disused Chornobyl nuclear power plant overnight.

A Russian drone attack has hit the radiation shelter protecting Chernobyl's damaged nuclear reactor, Ukrainian President Volodymyr Zelensky has said. The overnight strike at the nuclear plant, which is the site of the world's worst nuclear accident, caused a fire that has since been extinguished, he added.
