This report delves deeper, documenting the cases of 101 individuals who, between March 2013 and March 2017, were held incommunicado, tortured, and sometimes killed by Cameroonian security forces in facilities run by the military and intelligence services. Despite such practices being in violation of both national and international law, the use of torture in Cameroon’s fight against Boko Haram has become widespread and routine, and practiced with impunity. These constitute violations of international human rights law, as well as violations of international humanitarian law that amount to war crimes.
