The 1989-1997 civil war in Bougainville, Papua New Guinea left as many as 20,000 dead. The fate and whereabouts of many who vanished following the outbreak of violence remain unknown. This causes anguish and uncertainty for families and friends who are often unable to grieve. Under international humanitarian law, families have the right to be informed of the fate of missing relatives. Governments, military authorities and armed groups have an obligation to provide answers.ICRC delegate Brendan St John explains one of the ways ICRC is supporting these families.
