Exodus Grows as 150,000 People Flee Russia’s Ukraine Invasion. Millions May Follow

More than 150,000 people have fled Ukraine since Russia launched an unprovoked military invasion last week, the United Nations High Commissioner for Refugees said Saturday, an exodus that the U.N. estimates could grow to as many as 5 million. The U.N.’s refugee agency said half of those fleeing had headed to the 300-mile border with Poland, where U.S. forces are helping with preparations for new arrivals, while other displaced civilians left for Hungary, Moldova and Romania.
