Russian troops have seized Ukraine's largest nuclear power plant in Ukraine, which burned down during the rally that night. Russia's defence ministry has accused Ukrainian divers of the attack and called it a terrifying provocation.
Here are the 10 latest developments of Russia's invasion of Ukraine:
1. "The territory of the Zaporozhye nuclear power plant is occupied by the armed forces of the Russian Federation," the Ukrainian Nuclear Inspectorate told AFP. The statement said the plant's employees continued to operate the reactor and power source in accordance with current safety regulations.
2. The Zaporozhye power plant burned down because it was attacked by Russian troops. Although the fire was later extinguished, the incident raised fears that radiation could escape from the damaged headquarters.
3. US Secretary of Energy Jennifer Granholm said the reactors at the Zaporozhye nuclear power plant were station "are protected by robust containment structures and reactors are being safely shut down". Ms Granholm said on Twitter that she had recently spoken to the Minister of Energy of Ukraine about the state of the power plant. "We have seen no elevated radiation readings near the facility," Ms Granholm said.
4. Ukrainian President Volodymyr Zelensky accused Moscow of trying to "reverse" the Chernobyl nuclear disaster and said he had spoken to international leaders, including US President Joe Biden, about the Zaporozhye nuclear crisis.
5. Pictures of the site's live broadcast previously showed explosions that illuminate the night sky and emit clouds of smoke, and the International Atomic Energy Agency immediately urged them to stop fighting there. "No country other than Russia has ever fired on nuclear power units," Mr Zelensky said in a video message.
6. "This is the first time in our history. In the history of mankind. The terrorist state now resorted to nuclear terror. If there is an explosion, it is the end of everything. The end of Europe. This is the evacuation of Europe. Only immediate European action can stop Russian troops” said Zelensky, calling for international help.
7. On Friday after the attack on the nuclear power plant, the British Prime Minister Boris Johnson accused Russian President Vladimir Putin of endangering the whole of Europe. "The Prime Minister said the reckless actions of President Putin could now directly threaten the safety of all of Europe,” he said in a statement on Downing Street.
8. The station in Zaporozhye, an industrial city in south-eastern Ukraine, supplies an estimated 40 percent of the country's nuclear energy and, according to Zelenský, contains six of Ukraine's 15 reactors.
9. Ukraine's nuclear facilities became a major point of interest after the Russian army invaded the country last week and began bombing cities with grenades and rockets.
10. A nuclear power plant disaster in Ukraine's Chernobyl in April 1986 was one of the worst disasters in the history of nuclear power generation. Mistakes by engineers and compounded by other factors led to an uncontrolled chain reaction that resulted in several massive explosions in Chernobyl in 1986.
