Set up in May 1948, the United Nations Truce Supervision Organization, UNTSO was the first ever peacekeeping operation established by the UN. 

In an interview with UN News, Major General Patrick Gauchat, Head of Mission and Chief of Staff, explained the mission has evolved since it was first established to monitor ceasefires and support peace agreements in the aftermath of world war. 

Working closely with UN forces in Lebanon and the Golan, UNTSO complements their security, medical, and engineering operations. And with the mandate extension in Lebanon ending in December 2026, the truce supervision mission could take on a bigger role along ceasefire lines.

Mr. Gauchat told UN News’s Khaled Mohamed the longest-running mission’s presence gives reassurance to civilians living in conflict areas.
