Ukraine state energy company Energoatom said the Zaporizhzhia nuclear power complex was shelled on Thursday, putting the blame on Russian forces that seized the area in March.
Energoatom said the plant's area was struck five times, including near the site where radioactive materials are stored, but that nobody was injured and the situation at the plant remained under control.
Earlier in the day, the Russian state-owned news agency TASS said Ukraine shelled the plant for a second time on Thursday, citing the Russian-installed local administration. Reuters could not independently verify the reports of either side.
