United Nations Security Council Resolution 451, adopted on 15 June 1979, 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 expressed its concerns regarding actions which could heighten tensions, and asked the Secretary-General to report back again before 30 November 1979 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 December 1979.
The resolution was adopted by 14 votes to none; China did not participate in the voting.
