“Last night, a Russian attack drone with a high-explosive warhead struck the shelter protecting the world from radiation at the destroyed 4th power unit of the Chornobyl Nuclear Power Plant,” Ukrainian president Volodymyr Zelenskyy said of the attack.

Ukraine said a Russian drone crashed into the containment structure, starting a fire, but so far radiation levels have stayed constant.

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.
