UNTSO

Our Mission

For 75 years, UNTSO has symbolized the legitimacy and commitment of the United Nations to the pursuit of comprehensive peace in the Middle East. It continues to do so, and its value remains essential.

Its mandate, though seemingly simple, allows the Mission to be flexible, effective, and relevant in a complex region. The value of UNTSO’s expert military observers in support of UNIFIL and UNDOF mandate implementation is undisputed. UNTSO’s regional liaison mandate allows the Mission to analyze and assess multifaceted political and security issues, and its regional footprint complements other UN missions in the region, adding strategic-level value to the over-arching goals of the United Nations.

UNTSO remains first in peace, until a lasting peace.
