An attack on a nuclear facility could cause an irreparable catastrophe. It would be an outrageous act against humanity and civilized society that could never be forgiven.
In Russia's continued invasion of Ukraine, a fire broke out at the Zaporizhzhia nuclear power plant in the southeast. The blaze was successfully extinguished and no changes in radiation levels have been recorded at this time, but the nuclear plant was reportedly seized by Russian forces.
Up to this point, there has never been a case of an operating nuclear power plant coming under military attack. The Geneva Conventions, aimed at lessening damage from armed conflict, prohibits the targeting of nuclear power plants. The Russian forces' military action that brought about this situation is a violation of international law.
