Work on the line, which was damaged and disconnected as a result of military activity on January 2, should start "in the coming days", the UN nuclear watchdog said in a statement.

"This temporary ceasefire, the fourth we have negotiated, demonstrates the indispensable role that we continue to play," said IAEA director general Rafael Grossi.

The Vienna-based International Atomic Energy Agency said its team at the site heard "a large number of explosions, including some within the vicinity of the site".

"The team... has reported multiple air raid alarms each day over the past week and were informed that a military flying object had been observed approximately 10 kilometres (six miles) from the site," it added.

Zaporizhzhia is the biggest nuclear power plant in Europe and has been occupied by Russian forces since March 2022.

Situated on the Dnieper river, its six reactors have been shut down since the occupation.

But the site still needs electricity to maintain its cooling and security systems.

Moscow and Kyiv have repeatedly accused the other of risking a nuclear catastrophe by attacking the site.
