(FILES) Soviet television showed, on April 30, 1986, this picture of the Chernobyl plant on which a half-destroyed building could be seen, but commentary said there had been "no destruction, nor gigentic fires nor thousands of casualties". Ukraine will on April 30, 2026 mark the 40th anniversary of the Chernobyl accident, the worst civilian nuclear disaster in history. The risks of new radioactive releases still remain today, as the site is threatened by Russian strikes after it invaded the neighbour four years ago. (Photo by AFP via Getty Images)
