UN Warns Yemen on Brink of Large-Scale Conflict as Truce Frays

The United Nations has issued a stark warning that Yemen is at a greater risk of sliding back into large-scale conflict than at any point since 2022. A recent escalation in tit-for-tat strikes between the Iranian-backed Houthi movement and the Saudi-backed internationally recognized government threatens to unravel the truce that has largely held since 2022.

The current cycle of violence began on July 13 with a Saudi-led coalition airstrike on the runway of Sanaa International Airport. The strike prevented the landing of an Iranian flight carrying a high-ranking Houthi delegation. The flight, operated by Mahan Air, was an attempt by the Houthis to challenge the coalition's decade-long control over Yemeni airspace, which requires prior permission for all flights. The rebels had reportedly turned down an offer to travel on a non-Iranian airline.

In response to the airport strike, the Houthis announced a blockade on Saudi shipping in the Red Sea, attacking Saudi vessels and oil facilities inside the kingdom. The group also targeted Abha airport in southwestern Saudi Arabia. The Saudi-led coalition retaliated with strikes on Hodeida and Kamaran island, and has reinforced troops along front lines in preparation for a potential ground offensive.

Anticipating such an offensive, the Houthis have launched dozens of missiles and drones at military camps in central and southern Yemen, killing dozens of troops and civilians. A strike on the port city of Mokha, which remains under government control, killed at least three civilians and caused significant damage to the crucial port.

Yemen's location along the Bab el-Mandeb Strait, a vital chokepoint for roughly 12 percent of global trade, adds a significant economic dimension to the conflict. With the Strait of Hormuz closed due to the U.S.-Israeli war with Iran, Saudi Arabia has become more reliant on Red Sea routes for its oil exports, leaving its economy and the global market vulnerable to disruption. Shipping firms have already reported a decline in tanker traffic through Bab el-Mandeb since the attacks began in July.

The Houthis appear to be leveraging this vulnerability to press for political and economic concessions from Saudi Arabia, including the lifting of the blockade on territories they control. Oman has been engaged in back-channel diplomacy to salvage the 2022 truce but has yet to broker a compromise between the two sides.
