Ukraine has claimed “explosive devices” have been placed on the roof of the Zaporizhzhia nuclear power station, as Volodymyr Zelenskyy warned of “dangerous provocations” at the facility.
The Ukrainian armed forces quoted “operational data” as saying that the devices had been placed on the roof of the plant’s third and fourth reactors on Tuesday, adding that an attack was possible “in the near future”.
Ukrainian president Mr Zelenskyy said: “Now we have information from our intelligence that the Russian troops have placed objects resembling explosives on the roof of several power units of the Zaporizhzhia nuclear power plant.
“Perhaps to simulate an attack on the plant. Perhaps they have some other scenario.”

Throughout the war, nuclear experts have repeatedly warned of a potential disaster at the Russian-occupied plant in southern Ukraine.
An adviser of Russia’s nuclear power operator Rosenergoatom said Ukraine planned to drop ammunition laced with nuclear waste transported from another of the country’s five nuclear stations on the plant.
Renat Karchaa, an adviser to the head of Rosenergoatom, was quoted by Russian media as saying that Ukraine’s military will try to attack the plant on Wednesday “using long-range precision equipment and kamikaze attack drones”.
Both Mr Karchaa and Ukraine proed no eence for their assertions.
Recent warnings have led to a number of Ukrainians trying to leave the country with queues at the border crossing to Moldova running for two miles.
The Ukrainian government has also issued guidance on what to do in the event of a nuclear emergency.
Moscow and Kyiv have repeatedly accused the other of shelling around the facility, which is Europe’s largest nuclear plant with six reactors.

Mr Zelenskyy said over the weekend that a “serious threat” remains at the plant, with Ukrainian intelligence suggesting Russia was “technically ready” to provoke a localised explosion at the facility.
It also claimed that the number of Russian personnel at the plant is gradually being reduced – Moscow has not commented on the apparent drawdown.
The UN’s nuclear watchdog, the International Atomic Energy Agency (IAEA), has tried to clinch a deal to ensure the plant is demilitarised and reduce risks of any possible accident.
When Russia claims Ukraine is about to do something it often means they are about to do it themselves
It was a nerve-wracking night for Ukrainians and the anxiety goes on.
Having a nuclear power plant in enemy hands has been the cause of deep concern for Ukrainians throughout the war. Never more so than now.
When Russians claim the Ukrainians are about to do something it often means they are about to do it themselves, most recently with the Kakhovka Dam shortly before it’s believed the Russians blew it up.
So claims by Russians that the Ukrainians were about to attack the Zaporizhzhia power plant last night were deeply worrying.
This is what we know about the plant.
Sky sources at the plant say they have noticed a reduction in the number of patrols there and Ukrainian military intelligence says it believes Russians have partially withdrawn from the plant.
That may or may not be a sign they are planning to create an incident there.
The good news is the International Atomic Energy Agency said a few days ago there were no signs of explosives being laid there.
We are in the thick of an information war and the Russians have had no qualms about using their control of the plant to spread fear before.
What worries the Ukrainians most is what Russia did to the Kakhovka dam a month ago and the muted response from the rest of the world.
It created a massive disaster by unleashing the contents of Europe’s second-biggest reservoir, flooding the homes of tens of thousands of people downstream and depriving the same number of water upstream.
Voices in the West condemned the move but a delegation of African leaders came to Ukraine the week after and made little of it, urging both sides to de-escalate instead.
Their determination to find a moral equivalency between invaders and the invaded utterly infuriated the Ukrainians.
If Putin was testing the water for his next act of mass destruction he will hardly have felt deterred, making the Ukrainians’ jitters over Zaporizhzhia all the more understandable.

Last week, it said it had “so far found no visible indications of mines or other explosives currently planted” at the facility, but said it was aware of the reports and needed additional access to carry out further such checks at the site.
The biggest nuclear risk at the plant is from overheating nuclear fuel, which could happen if the power that drives the cooling systems is cut or if there is not enough water to supply the cooling systems.
Shelling has repeatedly cut power lines.
