Ukrainian President Volodymyr Zelenskyy has denounced Russia as Ukraine commemorated its victory over Nazism in World War Two.
Zelenskyy released a video message online on Wednesday.
Last year, Ukraine designated May 8 as the Day of Remembrance and Victory over Nazism. Nazi Germany surrendered on that day in 1945. Ukraine's move was apparently made to differentiate itself from Russia, which marks Victory Day on May 9.
In the message, Zelenskyy said: "Eighty years ago, millions of Ukrainians fought to defeat Nazism forever. But today, Ukrainians are once again standing up to evil, which reemerged, returned and wants to destroy us again." He went onto say, "This evil is called Russian fascism."
Zelenskyy said the video was shot in the basement of a school in the northern region of Chernihiv, where some 350 residents, including children, were held at the early stage of the Russian invasion. He said everyone can understand what Putin's Russia is by imagining what it would be like to be kept in the basement without light, food, water and other necessities.
The president called on countries to unite under an "anti-Putin coalition." He said the world can stop "Moscow Nazis" through actions, not words, and prevent the "new evil" from spreading to the whole of Europe and the entire world.
