United Nations Observer Group in El Salvador

ONUSAL was established on 20 May 1991 by Security Council resolution 693 (1991). It mandate was to verify the implementation of all agreements between the Government of El Salvador and the Frente Farabundo Martí para la Liberación Nacional aimed at ending a decade-long civil war. The agreements involved a ceasefire and related measures, reform and reduction of the armed forces, creation of a new police force, reform of the judicial and electoral systems, human rights, land tenure and other economic and social issues. After the armed conflict had been formally brought to an end in December 1992, ONUSAL verified elections which were carried out successfully in March and April 1994.
