KASSAB, Sudan — On Saturday morning at Kassab camp, outside Kutum town in northern Darfur, more than 50 patients awaited treatment at a GOAL clinic. The facility is one of two provided by the Irish NGO to service a camp where 18,000 IDPs have been resident, most for at least two years, some for three. Seven boys aged between 12 and 15 sat waiting for treatment for conditions varying from football injuries to stomach pains and fever symptoms. Mohammed, 15, thought he just had a cold. While waiting to see the doctor he said that he does not always have enough food and feels weaker than he did when he was living in his village. It is 32 degrees celsius, sat beneath a tree in the yard, shaded from the sub-Saharan sun. “Sometimes people come here at night, sometimes they steal things, sometimes they kill people. Just two weeks ago, a shooting took place near my shelter. Janjaweed came into the camp and did it,” he said.
