Ukraine on Monday said tens of thousands of people have likely been killed in Russia's assault on the southeastern city of Mariupol while the country's rights ombudswoman accused Russian forces in the region of torture and executions.
Reuters has confirmed widespread destruction in Mariupol but could not verify the alleged crimes or the estimate of those killed in the strategic city, which lies between Russian-annexed Crimea and eastern areas of Ukraine held by Russian-backed separatists.
