Ukrainian officials have denied Russian claims its forces have captured Zaporizhzhia nuclear power station - the largest in Europe.
Energoatom, Ukraine's state-run nuclear company, told the Interfax news agency that such claims by Moscow are "an absolute lie, a fake".
Earlier on Monday Russia said its troops had seized the plant and operations were continuing as normal.
Maj Gen Igor Konashenkov of the Russian defence ministry said in a statement: "Russian servicemen are fully guarding and controlling the area around the Zaporizhzhia nuclear power plant."
He added: "Personnel continue to work on maintenance of facilities and control of the radioactive situation in the normal mode. The radioactive background is normal."
