Two members of security staff were injured when the projectile hit overnight after the Ukrainian authorities reported a battle with Russian troops near Europe's biggest power plant, which is operating at just a small fraction of its capacity with one of its six units still running.

The Ukrainian nuclear regulator said that the fire had been extinguished and no radiation leak had been detected, with site staff still able to work at the Zaporizhzhia site.

"No country other than Russia has ever fired on nuclear power units," he said in a video message released by his office. "This is the first time in our history. In the history of mankind. The terrorist state now resorted to nuclear terror."

"If it blows up, it will be 10 times larger than Chornobyl!" the minister said, referring to one of the world's worst nuclear disasters that occurred in 1986 at the Chernobyl plant in Ukraine, then part of the Soviet Union.

"IAEA Director General @RafaelMGrossi speaks with #Ukraine PM Denys Shmygal and with Ukrainian nuclear regulator and operator about serious situation at #Zaporizhzhia Nuclear Power Plant, appeals for halt of use of force and warns of severe danger if reactors hit," the International Atomic Energy Agency tweeted.

Indonesia's envoy to the United Nations said that the international community must go beyond condemnation and start “restoring trust and confidence”, as analysts predict the potential effects of the Ukraine crisis.

But the failures of the first days, including vastly underestimating the Ukrainians' willingness to fight back, could lead to a frustrated Moscow deciding to unleash all its power and indiscriminately destroying large swathes of Ukraine, they said.

Moscow's offensive marks a turning point for the whole world.

The shelling of Kharkiv has destroyed a school and, according to its mayor, killed at least 11 civilians. 

The troops will train in long-distance movements of military units, among other tasks, the district command said.

Rafael Grossi, director general of the International Atomic Energy Agency, said he had received reports that the soldiers were close to the Zaporizhzhia station in eastern Ukraine.

Ukraine has said its goal for the talks is an immediate ceasefire and the withdrawal of Russian forces from Ukraine. Russia has been cagier, with the Kremlin declining to comment on Moscow's aim in negotiations.

In October 1962, at the heart of the Cold War, a 13-day showdown between Soviet leader Nikita Khrushchev and US president John F. Kennedy leads to fears of nuclear war.

The conflict has already killed dozens of civilians, forced hundreds of thousands to flee and turned Moscow into a global pariah.

"This is terror. They are going to bomb our Ukrainian cities even more, they are going to kill our children even more subtly. This is the evil that has come to our land and must be destroyed," Zelenskiy said on a short video message.

"We call on all relevant parties to exercise maximum restraint and make utmost efforts to pursue dialogues through all channels, including diplomatic means to contain the situation," the ministers said in a statement dated Saturday.

The measures, which will include restrictions on the Russian central bank's international reserves, will be implemented in the coming days, the nations said in a joint statement that also vowed further action to come.

"I can tell you one thing this morning it is that this war will last," Macron's told France's annual agriculture fair.

"We're all here. Our military is here. Citizens in society are here. We're all here defending our independence, our country, and it will stay this way," Zelensky said, standing outside the presidency building.
