Ukraine president Volodymyr Zelenskyy has warned that Europe is 'one step away' from a complete disaster.
It came as power was cut to the two remaining working reactors at the Zaporizhzhia nuclear station - which is currently the site of one of the major battles after Russia's illegal invasion of their neighbour.
Ukraine's state nuclear company Energoatom believe that fires in nearby ash pits at a coal power station close to the complex had caused the disconnection from the reactors from the power grid.
