Russian drone hits Chernobyl nuclear plant । Watch #ukrainewar #russia #chernobyl Ukrainian President Volodymyr Zelensky said a Russian drone strike had hit the radiation shelter protecting Chernobyl's damaged nuclear reactor. He also said the overnight attack on the nuclear power plant, site of the world's worst nuclear accident, caused a fire that has since been extinguished. As of Friday morning, radioactivity levels inside and outside Chernobyl remained normal and stable, according to the United Nations Atomic Energy Organization (IAEA). Russia has denied any claims of an attack on Chernobyl, saying its military does not attack Ukraine's nuclear infrastructure and that "any claims that it did so do not correspond to reality". The International Atomic Energy Agency (IAEA), which monitors nuclear safety around the world, said firefighters and vehicles responded within minutes of the explosion overnight.The agency also said no casualties were reported. The agency remains on "high alert" following the incident, with its director general Rafael Mariano Grossi saying there is "no room for complacency". In 1986, a catastrophic explosion at Chernobyl sent a plume of radioactive material into the air, creating a public health emergency across Europe.
