E/CN.4/1995/111 page 8 per day: six as victims of political killings, one in the context of "social cleansing" and three in armed confrontations. Between January 1993 and March 1994, members of the State security forces (50.28 per cent) and paramilitary groups (18.98 per cent) together were imputed to have committed almost 70 per cent of alleged extrajudicial, summary or arbitrary executions. Guerrilla groups (24.79 per cent) and militias (4.57 per cent) 5/ were said to account for the remaining 30 per cent. However, in approximately 77 per cent of all cases, the authorship of violations of the right to life could not be ascertained. For the same period, Justicia y Paz recorded 436 cases of torture 6/. Furthermore, one person is said to disappear every day, leading to a total of 700 cases of disappearances reported by Justicia y Paz for the period between June 1990 and June 1994. In many cases, the victims are reportedly found dead a few days after their disappearance. The Working Group on Enforced or Involuntary Disappearances currently has 717 cases of unresolved disappearances in Colombia on its books. 7/ 21. In its most recent annual report, dated July 1994, the Procuraduría General de la Nación presented an overview of the complaints received during 1993. With respect to violations of the right to life and physical integrity allegedly carried out by security forces, the Procuraduría noted with alarm an increase by 23 per cent and 18 per cent, respectively, compared with complaints received in 1992. Concern is also expressed at a tendency witnessed between 1990 and 1993 whereby torture and homicides constitute an increasingly large proportion of the complaints received: while in 1990 the ratio between abuses considered by the Procuraduría as "violaciones leves", such as arbitrary detention, illegal break-ins, threats, ill-treatment, etc., and torture/homicides was four to one, in 1993 it had become practically equal. In the majority of complaints presented to the Procuraduría, responsibility is attributed to members of the National Police (45 per cent) and of the military forces (30 per cent). 22. Both Special Rapporteurs have, over the past years, received numerous reports and allegations referring to cases of extrajudicial, summary or arbitrary executions and torture, as well as documents containing an analysis of the political, social and economic context in which such violations were taking place in Colombia in virtually absolute impunity. Both Special Rapporteurs have transmitted their concerns to the Government of Colombia in numerous urgent appeals and to the international community in their reports to the Commission on Human Rights. 8/ 23. During the visit of the Special Rapporteurs, all interlocutors stressed the need to take decisive and urgent steps to redress the situation of violence, the gravity of which is illustrated by the above figures. This violence finds its expression in human rights violations, including extrajudicial, summary or arbitrary executions and torture, by security forces and groups cooperating with them, particularly in the context of counter-insurgency activities, but also with a view to protecting particular economic privileges and interests; violent repression of those voicing political dissent and social protest; and elimination of persons regarded as undesirable in Colombian society. Large-scale and grave abuses by armed insurgents and armed groups at the service of drug traffickers or large landowners, as well as the extremely high levels of common criminality, add to the climate prevailing in Colombia. Land conflicts, particularly in areas
