In May 2005, Jane Best, president of Refugees International Japan, visited a refugee camp in Tanzania and met people who had fled conflicts in neighboring countries such as Rwanda, Ethiopia and the Democratic Republic of Congo.
A staff member at the camp pointed out one boy who was not interacting with the other children and kept clinging to adults. The boy, Best learned, had witnessed his parents being buried alive.
"He was obviously suffering from the scars from his parents' murder and the mental problems that went with that," Best said. "I suppose he was only about 10 or 12 — how can you witness that?"
