In response, the UN set up a refugee camp complex at Dadaab, in a remote part of Eastern Kenya. It became the largest refugee camp in the world. At its height Dadaab was home to 500,000 refugees, most of them Somalis. But the Kenyan government has now announced that it will close down the camp and return the refugees to Somalia.

We hear the story of Zamzam Abdi Gelle, a young woman who arrived in Dadaab 25 years ago, after her family was attacked in war torn Somalia.
