Ukrainian engineers have made further progress in repairing vital power infrastructure in the vicinity of the Zaporizhzhya nuclear power plant, the International Atomic Energy Agency said it was informed Tuesday.
The engineers are providing the plant with renewed access to a third back-up power line. This means all three back-up power lines to the power plant have been restored, according to the IAEA.
But, IAEA Director General Rafael Mariano still warned that safety at the plant remains precarious as it is under the control of Russian forces, but operated by a Ukrainian staff.
While there has been no shelling at or near Zaporizhzhya in recent days, it was still occurring in the wider area, Mariano said.
Zaporizhzhya's four main external power lines are all down and it is not currently providing electricity to households, factories and others.
