Two years have passed since Russia began a brutal invasion of Ukraine. In a press conference on Sunday, Ukrainian President Volodymyr Zelensky said that 31,000 Ukrainian soldiers and "tens of thousands" of civilians had died in the conflict, so far while many others have been injured. Estimates of Russian casualties vary widely, but US intelligence sources and the United Nations put the number near 100,000.
