By early 1995, the Kibeho IDP camp was the largest in Rwanda, sprawling for 9 square kilometers and containing between 80,000 and 100,000 people. UNAMIR presence at the camp was maintained by a Zambian infantry company, with medical services provided by Médecins Sans Frontières (MSF). The RPA maintained a tight cordon around the camp. Refugees wishing to leave the camp to return home had to pass through a checkpoint, where genocide survivors would point out individuals who had taken part in the 1994 killings.
