United Nations Security Council resolution 680, adopted 14 December 1990, noted a report of the Secretary-General that, due to the existing circumstances, the presence of the United Nations Peacekeeping Force in Cyprus (UNFICYP) would continue to be essential for a peaceful settlement. The Council asked the Secretary-General to report back again before 31 May 1991, to follow the implementation of the resolution.
The Council reaffirmed its previous resolutions, including Resolution 365 (1974), expressed its concern over the situation, urged the involved parties to work together toward peace and once more extended the stationing of the Force in Cyprus, established in Resolution 186 (1964), until 15 June 1991.
The resolution was adopted by 14 votes to none, with Canada abstaining from the vote.
