Dadaab

Picture a city of about 300,000 people - something the size of Tampa, Fla. or Riverside, Calif.

Now picture all of those people in this city being told it’s being closed down and they have to move.

That’s what the Kenyan government in East Africa is trying to do with the 340,000 people who live in Dadaab, the world’s largest refugee camp. Built 24 years ago by the U.N. to house people fleeing Somalia's civil war, many of the people living there today have never set foot in Somalia and don't want to go back.
