Russia has taken control of a nuclear power station in Ukraine after it was hit by shelling.
A fire broke out at the Zaporizhzhia nuclear plant â the largest in Europe â and Ukraine said it was shelled by Russian troops.
Authorities say the facility is now safe and radiation levels are normal.
World leaders have accused Russia of endangering the safety of an entire continent, and Ukraineâs president accused Russia of ânuclear terrorâ.
US President Joe Biden urged Moscow to stop its military activities around the site, while Canadaâs Prime Minister Justin Trudeau said the âhorrific attacksâ from Russia âmust cease immediatelyâ.
UK Prime Minister Boris Johnson said the ârecklessâ attack could âdirectly threaten the safety of all of Europeâ. All three leaders spoke to Ukraineâs President Volodymyr Zelensky by phone.
Mr Zelensky, meanwhile, said Russia wanted a repeat of Chernobyl, the site of the worldâs worst nuclear disaster in 1986.
âIf there is an explosion, it is the end of everything. The end of Europe,â he said.
A video feed from the nuclear plant showed blasts lighting up the night sky and sending up plumes of smoke.
Buildings around one of the plantâs six power units have been damaged without affecting its safety, according to Ukraineâs nuclear inspectorate.
Workers at the plant said the fire â which has since been extinguished â broke out at a training building outside the plantâs perimeter, and that only one of the plantâs six reactors were operational.
One resident who lives nearby said he saw the Russian military attacking the site. âIt is just terrorismâĤ It is worrying not just for our region, but for Ukraine and for the world,â Kirill Dovzhik told the BBC.
The UNâs nuclear watchdog, the International Atomic Energy Agency (IAEA), said the fire had not affected the plantâs âessentialâ equipment and there was no increase in radiation levels.
But the IAEA said it was in âfull 24/7 response modeâ due to the âserious situationâ at the power station.
Ukrainian emergency services said they were initially blocked from getting to the scene of the blaze, prompting President Biden to publicly call on Russia to allow firefighters into the site.
Boris Johnson said he would seek an emergency meeting of the UN Security Council on Friday over the attack.

Experts said attacking a nuclear plant was unprecedented, and the situation was still very dangerous.
Dr Graham Allison, a nuclear security expert at Harvard University, said the âworst caseâ would be if a fire at the plant caused a meltdown and prompted a release of radioactivity that contaminated the surrounding area for years.
But he also said it was more likely Russian forces were trying to âclose down the supply of electricity to the surrounding areaâ, rather than attack the plant.
The plant, located around 550km (342 miles) south-east of the capital Kyiv, generates almost a quarter of all electricity in Ukraine. It lies on the river Dnieper, north-east of the city of Kherson which is said to have been occupied by Russian forces.
The Russian military has also seized control of the Chernobyl nuclear plant, the site of the worst nuclear disaster in history.
News of the latest incident at Zaporizhzhia caused share prices in Asia to fall sharply.

More than one million people have fled Ukraine since the invasion began last week.
Despite punishing international sanctions, Russiaâs President Vladimir Putin said his offensive was going âstrictly according to schedule, according to planâ.
He has put his nuclear forces on high alert because of âaggressive statementsâ by the West.
Western ministers will hold crisis talks in Brussels on Friday as they seek to show their support for Ukraine.
UK Foreign Secretary Liz Truss called it âone of the biggest days of diplomacyâ with allies prepared to âtighten the vice around Putinâs war machineâ by targeting the Russian economy with more sanctions.
