Today is the International Day of the Disappeared. This Awareness Day was created to draw attention to the fate of individuals imprisoned at places and under poor conditions unknown to their relatives and/or legal representatives.
Back in December 2010, the UN General Assembly expressed its deep concern about the increase in enforced or involuntary disappearances in various regions of the world, including arrest, detention and abduction, when these are part of or amount to enforced disappearances, and by the growing number of reports concerning harassment, ill-treatment and intimidation of witnesses of disappearances or relatives of persons who have disappeared.
The Assembly quickly welcomed the adoption of the International Convention for the Protection of All Persons from Enforced Disappearance, and decided to declare 30 August the International Day of the Victims of Enforced Disappearances, to be observed beginning in 2011.
Last year, the UN chief called for action to end enforced disappearances. You can read about this here or yo can visit the UN's Website for more information about this Awareness Day.
