Russia has allegedly told workers at the Zaporizhzhia nuclear power plant not to show up to work Friday, Ukrainian military intelligence has exclusively confirmed to NBC News.

This comes amid allegations and speculation from both Russia and Ukraine that an incident is being planned Friday at the plant.

On Thursday, Russia threatened to shut down the plant, warning that there was a risk of a human-made disaster due to alleged continued shelling by Ukraine.

But Ukraine has a completely different story, according to Andriy Yusov, a spokesman for the Ukrainian Defense Ministry’s Main Intelligence Directorate.

“There is new information, it arrived about half an hour ago, that for tomorrow, August 19, there is an order for the majority of the staff not to go to work,” Yusov told NBC News.

“This is what the Russians told their people, primarily the employees of Rosatom,” he said, referring to the Russian nuclear agency.

He said that this might be evidence that Russia is preparing “large-scale provocations” at the power plant Friday.

“We do not rule out the possibility of massive Russian provocations on the territory of the ZNPP tomorrow. This is confirmed by their propaganda, information from our sources, and the behavior of the Russians at the station,” he added, referring to the Zaporizhzhia nuclear power plant.

Russia refused to confirm or deny whether any Rosatom personnel are stationed at Zaporizhzhia.

Earlier Thursday, the Russian Defense Ministry accused Ukraine and what it called its “U.S. handlers” of trying to stage a “minor accident” at the plant in southern Ukraine on Friday in order to blame Russia.

It said the “provocation” was timed to coincide with a visit to Ukraine by United Nations Secretary General Antonio Guterres and that it may involve a radiation leak.
