United Nations Security Council resolution 675, adopted unanimously on 5 November 1990, after recalling resolutions 637 (1989) and 644 (1989), the Council endorsed a report by the Secretary-General and decided to extend the mandate of the United Nations Observer Group in Central America for a further six months until 7 May 1991.
The resolution noted the need to remain vigilant of the financial costs of the Observer Group, given the increased demand on United Nations peacekeeping forces. It also requested the Secretary-General to report back before the end of the current mandate on all aspects of the Observer Group.
