SOUTH SUDAN — Flooding: Yel Aguer Deng walked through water from his compound to the Wanyhok-Akon road, near Malualkon in Northern Bahr el Ghazal State, on Wednesday. The worst flooding that parts of South Sudan have seen in 60 years surrounded his home of mud and grass. His field of sorghum, which fed his family, was underwater. The United Nations said the flooding affected almost a half-million people across South Sudan since May. Photo: Adrienne Surprenant/AP
