The United Nations Human Rights Council has approved a new international treaty to ban states from abducting individuals and hiding them in secret prisons or killing them. The treaty — which still has to be approved by the UN General Assembly — would require nations to keep registers of detainees and tell their families the truth about their disappearance. The United States is not expected to ratify the pact, the International Convention for the Protection of All Persons from Enforced Disappearance.
