Inside the Georgia city that has become a home away from home for refugees: "The people are very loving"

The plight of the world's refugees has come into special focus following Russia's invasion of Ukraine. The U.N. refugee agency says more than 1 million people have fled to Poland, Hungary, and other nations, and millions more could follow.

In the United States, the most recent influx of refugees came last summer, following the fall of Afghanistan. One place where they have been welcomed is the city of Clarkston, Georgia. 

Over four decades, the city has hosted so many refugees from so many places that it has become known as "the most diverse square mile in America."
