Switzerland’s ABC of International Humanitarian Law (2009) states:
Enforced disappearances and arbitrary detention
Enforced disappearances violate International humanitarian law and Human rights. No conflict and no national security considerations can justify such disappearances. The Convention for the Protection of All Persons from Enforced Disappearance was adopted in 2006 but has not yet come into force (status 2008). International humanitarian law nonetheless contains provisions on the enforced disappearance of persons following an armed conflict. In particular, their next of kin have the right to know what has happened to them.
