This photo taken on June 15, 2012, at the Jamam refugee camp, shows mothers queueing at a Medecin Sans Frontiere (MSF) field hospital in South Sudan's Upper Nile state, where over 100,000 refugees have fled conflict in Sudan's Blue Nile state since September. MSF says malnutrition in refugee camps is way above emergency levels and especially amongst under five year-olds, that suffer dehydration and diarrhoea from a lack of clean water.
