United Nations Security Council Resolution 458, adopted on 14 December 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 31 May 1980 to follow the implementation of the resolution.
