Ukraine’s nuclear ghosts have been stirred up again after a drone armed with a warhead hit the protective outer shell of the plant at Chernobyl, the site of the world’s worst nuclear accident. The strike on Friday did not breach the plant’s inner containment shell and radiation levels did not increase.

A Russian drone struck the former nuclear power plant at Chernobyl in an attack overnight into Friday, Ukrainian President Volodymyr Zelensky has said.

A Russian drone attack badly damaged the confinement structure around the disused Chornobyl nuclear power plant intended to prevent the release of nuclear substances, a senior nuclear industry official said on Friday.
