The peacekeeping operations in the Middle East ( the United Nations Interim Force in Lebanon ( UNIFIL ) , the United Nations Iraq-Kuwait Observation Mission ( UNIKOM ) , and the United Nations Disengagement Observer Force ( UNDOF ) ) continued their excellent work . After lengthy discussions on the question of Western Sahara , the Council was able to adopt resolution 1429 ( 2002 ) , by which it extended the mandate of the United Nations Mission for the Referendum in Western Sahara ( MINURSO ) until 31 January 2003 .
