This paper will discuss the advisory services and technical assistance programme in the field of human rights available in the United Nations Centre for Human Rights/Office of the High Commissioner for Human Rights (OHCHR).[1] It will also discuss in detail the major components of the programme of advisory services and technical assistance in the field of human rights. It will examine in brief the situation of human rights in Nigeria from 1995 to 1998, at the peak of the regime of General Sani Abacha, the Head of State and Commander-In-Chief of the Armed Forces of Nigeria (November 1993 – June 1998), from the perspective of the UN alone. The sudden death of General Abacha in June 1998 brought to power another military ruler, General Abdulsalami Abubakar, who eventually handed over power on 29 May 1999 to an elected President, Gen. Olusegun Obasanjo (rtd), thereby ending a 15-year continuous rule of Nigeria by the military.
