Shortly after Russia invaded Ukraine in late February, the United Nations refugee agency (UNHCR) predicted that some 4 million people would flee the country throughout the course of the war.
In fact, that's how many Ukrainians left their homeland in just about the first month of the conflict. And that number surpassed 5 million last week.
The UNHCR now projects that some 8.3 million refugees will leave Ukraine, and the agency is calling for more financial support for them and their host countries.
