International Support and Verification Commission
The International Support and Verification Commission (Comisión Internacional de Apoyo y Verificación, CIAV) was created as a joint approach to repatriating the Contras by the secretaries-general of the United Nations and the Organization of American States on August 25, 1989 in support of the Esquipulas II Peace Plan. Its mandate was to assist in the voluntary demobilization, repatriation or resettlement of the Nicaraguan Resistance (the Contras) in Nicaragua and third countries as well as assistance in the voluntary demobilization of all persons involved in armed actions in all countries of the region.
