Sudan Lost Boys rediscover past in camp records

During the Sudanese civil war, thousands of young boys were displaced or orphaned - earning them the name 'Lost Boys'.

The US government and the UNHCR established a programme in which morethan 3,000 Lost Boys were allowed to resettle in America.

Diing Arok and Malek Deng talk to the BBC's Paul Adams about the recently discovered refugee camp records.

The documents give 13,000 refugees a glimpse into their past and serve as the only official documentation of their struggle.
