UNITED NATIONS OBSERVER GROUP IN CENTRAL AMERICA
ONUCA (November 1989 -- January 1992)

ONUCA was established in November 1989 to verify compliance by the Central American Governments with their undertakings to cease aid to irregular forces and insurrectionist movements in the region and not to allow their territory to be used for attacks on other States. In addition, ONUCA played a part in the voluntary demobilization of the Nicaraguan Resistance and monitored a ceasefire and the separation of forces agreed by the Nicaraguan parties as part of the demobilization process
