International Atomic Energy Agency experts at Ukraine’s Zaporizhzhia nuclear power station have in recent days and weeks inspected parts of the facility without observing any visible indications of mines or explosives, the agency’s director-general Rafael Grossi said.

Grossi said IAEA experts’ inspections included some sections of the perimeter of the large cooling pond and regular walkdowns across the site.

Grossi’s comments on Wednesday (5 July) followed renewed warnings by Ukrainian president Volodymyr Zelenskiy that Russia may be planning to “simulate an attack” on the Zaporizhzhia station, claiming that Russian troops have placed “objects resembling explosives” on the roofs of buildings at the site.

Citing Ukrainian intelligence, Zelenskiy said the objects had been positioned on the roof of several power units of the power plant that is currently held by Russia.
