This is WEEKEND EDITION from NPR News. I'm Susan Stamberg. Secretary of State Hillary Clinton is on a seven-country trip through Africa, talking about strengthening democracies, building economic growth. Yesterday, she dropped in South Sudan - that's the world's newest country - to encourage the infant nation. But she warned of so many challenges ahead. NPR's John Burnett was in South Sudan when the secretary was, and he joins us now on the line from Nairobi. Hi, John.
The teachers' staff-room is a charming thatched building adjacent to the classrooms overlooking the dusty recreation and assembly ground at Good Hope Basic Primary School in Bentiu, the capital of oil-rich Unity State in South Sudan.
Bentiu is near the disputed border with Sudan and within striking distance of Sudanese fighter jets and warplanes.
