United Nations Truce Supervision Organization
（重定向自UNTSO）
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).
