Several particular features of Operation Orión that the Office of the High Commissioner highlighted were the number of civilians killed during searches and arrests; the arbitrary deprivations of liberty and forced disappearances; violations of the right to privacy; and the inviolability of the home.124 For its part, the IACHR issued a press release on October 18, 2002, in which it expressed its concern over news reports that civilians were either killed or injured during Operation Orión.125 The Commission underscored “the obligation of the parties to the conflict to respect the norms of international humanitarian law, in particular the principles that distinguish between combatants and noncombatants, and concerning proportionality in the use of force.”126 It also reminded the State of its obligation to protect the civilian population, and the judicial and police authorities of their duty to investigate, prosecute and punish violations of these norms and principles.127 The IACHR also received information indicating that over 350 people were detained during Operation Orión.128 152. In the aftermath of these military operations, the IACHR received information confirming that paramilitary groups were rapidly making inroads into Comuna 13 and establishing 120 Panorama de Derechos Humanos, Noche y Niebla y Violencia Política en Colombia, Caso Tipo No. 2: Comuna 13, [Human Rights Picture, Night, Fog and Political Violence in Colombia], CINEP & Justicia y Paz, Bogotá, May 2003, p. 14; Audio, IACHR, Thematic Hearing, “Human Rights Situation in the Region of Antioquia and in Comuna 13 of Medellín, Colombia,” th October 16, 2012, 116 period of sessions. 121 United Nations, Report of the United Nations High Commissioner for Human Rights on the human rights situation in Colombia, Annual Report 2002, E/CN.4/2003/13, February 24, 2003, paragraph 28, available at: http://www.unhchr.ch/Huridocda/Huridoca.nsf/0/1304674285b7eb3bc1256cf5003906fb?Opendocument 122 United Nations, Report of the United Nations High Commissioner for Human Rights on the human rights situation in Colombia, Annual Report 2002, E/CN.4/2003/13, February 24, 2003, paragraph 37. 123 United Nations, Report of the United Nations High Commissioner for Human Rights on the human rights situation in Colombia, Annual Report 2002, E/CN.4/2003/13, February 24, 2003, paragraph 37. 124 United Nations, Report of the United Nations High Commissioner for Human Rights on the human rights situation in Colombia, Annual Report 2002, E/CN.4/2003/13, February 24, 2003, paragraph 46. 125 IACHR, Press Release No. 40/02, IACHR Concerned over the Situation of Comuna 13 in the City of Medellín, Colombia, October 18, 2002. 126 IACHR, Press Release, No. 40/02, IACHR Concerned over the Situation of Comuna 13 in the City of Medellín, Colombia, October 18, 2002. 127 IACHR, Press Release, No. 40/02, IACHR Concerned over the Situation of Comuna 13 in the City of Medellín, Colombia, October 18, 2002.. 128 United Nations, Report of the United Nations High Commissioner for Human Rights on the human rights situation in Colombia, Annual Report 2003, E/CN.4/2004/13, February 17, 2004, paragraph 12, available at: http://daccess-ddsny.un.org/doc/UNDOC/GEN/G04/109/93/PDF/G0410993.pdf?OpenElement.
