The United Nations Truce Supervision Organization (UNTSO) is an organization founded on 29 May 1948 for peacekeeping in the Middle East. Its primary task was providing the military command structure to the peace keeping forces in the Middle East to enable the peace keepers to observe and maintain the cease-fire, and as may be necessary in assisting the parties to the Armistice Agreements in the supervision of the application and observance of the terms of those Agreements. The command structure of the UNTSO was maintained to cover the later peace keeper organisations of the United Nations Disengagement Observer Force (UNDOF) and the United Nations Interim Force in Lebanon (UNIFIL).
The United Nations Mission for the Referendum in Western Sahara is the United Nations peacekeeping mission in Western Sahara, established in 1991 under United Nations Security Council Resolution 690 as part of the Settlement Plan, which had paved way for a cease-fire in the conflict between Morocco and the Polisario Front over the contested territory of Western Sahara.
The United Nations Observer Mission in Georgia (UNOMIG) was established by United Nations Security Council Resolution 858 in August 1993 to verify compliance with a 27 July 1993 ceasefire agreement between the Republic of Georgia and forces in Abkhazia with special attention given to the situation in the city of Sukhumi, Georgia. It was also to investigate reports of ceasefire violations, attempt to resolve such incidents with the parties involved, and to report to the Secretary-General of the United Nations on the implementation of its mandate. 88 military advisors were authorized to be deployed to the region. It ended on 15 June 2009, when Russia vetoed an extension of the mission. The last observers left the region on 15 July 2009.
Chapter VII of the United Nations Charter sets out the UN Security Council's powers to maintain peace.

The Resolution went on to relieve the Action Mediator in Palestine, as his duties had been fulfilled, and requested the Secretary-General arrange for the continued service of the personnel of the present Truce Supervision Organization as may be required in observing and maintaining the cease-fires and Armistices. The Resolution also requested that the Chief of Staff of the TSO report to the Council on the observance of the cease-fire.

The Council called upon both parties to give effect to any finding by the Commission, repatriating any such Arabs who the Commission believes to be entitled to return.

The Council called upon the parties of persons in the areas concerned to cease fighting and called them to comply with their obligations and commitments to previous resolutions and Agreements.

The Council condemned this attack as a violation of the cease-fire previsions of UNSC Resolution 54 and as inconsistent with the obligations of the parties under the General Armistice Agreement between Egypt and Israel and under the United Nations Charter. The Council again called upon Israel to take all necessary measures to prevent such actions and expressed its conviction that the maintenance of the General Armistice Agreement is threatened by any deliberate violation of it and that no progress towards the return of peace in Palestine can be made until both parties comply strictly with their obligations.
