Tensions involving Iran and regional actors have drawn concern from the United Nations. Initially, UN Secretary-General Antonio Guterres supported Iraq’s position that the state must maintain a monopoly on force following attacks on Saudi Arabia launched from Iraqi territory by Iran-backed militias.

As the situation progressed, the United Nations warned of escalating hostilities between the United States and Iran. Following new US sanctions, Iranian officials warned of harsh responses targeting military and economic interests in West Asia. Iranian leadership indicated that the reopening of the Strait of Hormuz is contingent upon the United States meeting specific conditions. The UN has emphasized that a durable settlement requires dialogue and has noted the mediation efforts of Qatar, Egypt, and Pakistan.
