Ukraine said Russia's assault on the eastern part of the country is continuing, with 38 towns hit in the Luhansk and Donetsk areas on Monday, damaging civilian infrastructure.
Ukraine remains at the top of the agenda at the World Economic Forum in Davos. Ukrainian President Volodymyr Zelenskyy addressed leaders of the business and political world at the summit via video link on Monday.
He said the world is at a "turning point" and must decide whether it would allow Russia's "brute force" to win. Russian politicians, business leaders and academics are absent from the event this year.
Meanwhile, a Russian soldier was sentenced to life in prison on Monday in the conflict's first war crimes trial. As the war drags on, the United Nations said that more than 6.5 million Ukrainians have become refugees.
