Children in Sudanese refugee camps

Theresa is one of many children living in an IDP (Internally Displaced Persons) camp near Khartoum. These camps are home to 2.2 million people, the largest concentration of displaced people in the world who have been forced from their homes because of the decades of conflict between north and south Sudan. 57% are under 20 years old Photograph: Felicia Webb/Save The Children
