There was a 1999 annual report about death squads in Colombia,[7] but it did not mention any non-Colombian involvement, other than the UN Commission on Human Rights. "Some of these concerns were addressed in a statement by the Chairman of the Commission which expressed concern about the gravity and scale of human rights violations and breaches of international humanitarian law and, inter alia, urged the government to take steps to end impunity and to take effective action to prevent internal displacement. The Commission welcomed the agreement with the Colombian government to extend the mandate of the office of the un High Commissioner for Human Rights in Colombia until April 1999."
