Ukrainian President Volodymyr Zelensky claimed on Tuesday night that Russian troops have placed possible explosives on the roof of several power units of the Zaporizhzhia nuclear power plant.

"It is the responsibility of everyone in the world to stop it, no one can stand aside, as radiation affects everyone," Zelensky said in a late-night address.

Russian troops have occupied Europe's largest nuclear facility since March 2022. Since then, both sides have regularly accused each other of risking a major nuclear disaster.

Now, both Russia and Ukraine are accusing each other of plotting an attack at the nuclear power plant.
