Repairs have been completed on a key power line and other energy infrastructure vital for nuclear safety at the Russia-controlled Zaporizhzhya nuclear power station in Ukraine, as part of efforts to strengthen its access to the electricity grid and help reduce the risk of a nuclear accident during the military conflict, International Atomic Energy Agency (IAEA) director-general Rafael Grossi said.

The technically complex repairs, preceded by extensive de-mining, were carried out on the frontline under the protection of a localised ceasefire mediated by the IAEA.

Agency teams monitored the work in challenging conditions, including nearby drone activity and the sound of military activity in the area.
