Summary: Nearly 10 percent of Ukraine's population has been displaced in almost three weeks of war. While almost 2 million people have moved within the country's borders, over 2 million more have fled. The majority of those Ukrainians are escaping the war to the west by crossing into Poland. Special correspondent Malcolm Brabant reports on the exodus from the Polish capital of Warsaw. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders
