After a peace deal two years ago to end south Sudan's two-decade war, its once isolated capital, Juba, is now teeming with people returning home and United Nations peacekeepers.

The number of children living on Juba's streets is growing, many abandoned or separated from parents during the war. Some boys and girls are now turning to prostitution.

Some UN personnel are at the centre of child sex abuse allegations. This Juba street child holds up money she says she made the night before by sleeping with a peacekeeper.

There is little awareness of HIV/Aids in south Sudan, or of how it is transmitted. Here an HIV patient lies in the infectious disease unit of Juba Teaching Hospital.

This woman is recovering from a violent attack. For women and children there is no recourse for abuse, either sexual or physical, and many cases go unreported.

Another mother holds the hand of her newborn baby, who she says was fathered by a UN peacekeeper. She believes he has now gone back to his home in Bangladesh.
