YIDA REFUGEE CAMP, SOUTH SUDAN - JULY 1: Sudanese refugees listen to a sermon as they pray in a makeshift church at the Yida refugee camp, close to the border with North Sudan, on July 01, 2012 in Yida, South Sudan. The Yida refugee camp has swollen to nearly 60,000, as refugees flee from South Kordofan in North Sudan, with new arrivals at 300-600 a day. The rainy season has increased the numbers of sick children suffering from diarrhea and severe malnutrition, as the international aid community struggles to provide basic assistance to the growing population. Most have arrived with only the clothes they are wearing. Many new arrivals have walked from between 5 days and 2 weeks or more to reach the camp. (Photo by Paula Bronstein/Getty Images)
