A Saudi airstrike on July 13, 2026, disabled the runway at Yemen’s capital, Sanaa, preventing an Iranian flight carrying a high-ranking Houthi delegation from landing. This direct act of military control over Yemeni airspace immediately triggered a new surge in fighting, threatening to unravel a fragile truce and pull the country deeper into a wider regional confrontation.
The United Nations envoy for Yemen, Hans Grundberg, warned that Yemen now faces a greater risk of renewed large-scale conflict than at any point since the U.N.-brokered truce of April 2022. He stated that the escalation jeopardizes the gains of that truce, now in its fourth year, and risks drawing Yemen into a broader regional confrontation with devastating consequences for its people. Grundberg has held intensive talks with Yemeni parties and regional governments to try and avert further escalation.
Escalating Blockade and Control
The Houthis had attempted to fly the plane without prior permission from the Saudi-led coalition, a requirement in place for a decade due to the ongoing war. The group saw this as a direct challenge to the coalition’s control over Yemeni airspace and a way to establish new facts on the ground. Government and Houthi officials, speaking anonymously, confirmed the Houthis rejected an offer from the Saudi-backed internationally recognized government to arrange the delegation’s travel on a non-Iranian airline. Instead, the group proceeded with the flight operated by the Iranian privately owned, U.S.-sanctioned Mahan Air, which led to the Saudi-led strike that disabled Sanaa airport. A Gulf official, also speaking anonymously, indicated the Saudi-led coalition later allowed the flight to land in the Houthi-controlled city of Hodeida as part of an Omani-led effort to avert further escalation.
Following the Sanaa airport strike, the Houthis launched retaliatory attacks. They struck the Abha airport in southwestern Saudi Arabia and announced a blockade on Saudi shipping in the Red Sea. The group also attacked Saudi vessels and oil facilities inside the kingdom, adding further disruption to the global economy. In response, the Saudi-led coalition conducted strikes on Hodeida and Kamaran, Yemen’s largest island in the Red Sea. Yemeni officials reported that the coalition also reinforced Yemeni troops along the front lines, preparing for a ground offensive on the Houthis. Anticipating this offensive, the rebels launched dozens of missiles and drones at military camps in central and southern Yemen, killing dozens of troops and civilians. They also attacked the Red Sea city of Mokha, severely damaging its crucial port, which remains under the control of the internationally recognized government. On Sunday, Houthi rebels attacked a Red Sea port town controlled by government forces, killing seven people and injuring 30, according to Yemen’s Defense Ministry, which operates under the internationally recognized government. The ministry specified four military personnel and three civilians were killed. The Houthi group reported a 13-year-old child was killed by artillery shelling and another child injured in clashes continuing Monday near the village of Taiz.
Humanitarian Catastrophe Deepens
The war has plunged Yemen into one of the world’s worst humanitarian crises. People living in Houthi-held territories are experiencing the most severe hunger. In recent years, the Houthis have faced growing internal pressure due to deteriorating living conditions in their territories. Salah Ali Salah, a Yemeni researcher, noted that a prolonged situation of “no war, no peace” has raised public expectations for tangible economic and living improvements, creating significant internal pressure on the group. He stated the Houthis have sought to blame Saudi Arabia for its air and naval blockade on their territories. They have framed the escalation as an extension of the ongoing Yemen war, rather than a new front in the Iran war.
This blockade forms a central part of the war effort by the Saudi-led coalition, which entered the conflict in March 2015, now in its eleventh year. The coalition intervened six months after the Houthis descended from their northern stronghold and took control of Sanaa, forcing the government to flee first to the south and then to Saudi Arabia. The conflict eventually deteriorated into a stalemate, leading to the April 2022 truce that ended major fighting across the country and stopped Houthi missile and drone attacks on Saudi Arabia and the United Arab Emirates, which quit the coalition over a year ago.
Assertion of Sovereignty
Ahmed Nagi, a senior Yemen analyst at the International Crisis Group, observed that the escalation reflects a broader shift in Houthi priorities. He explained that the focus moved from trying to extract confidence-building measures, such as payment of salaries to civil servants in Houthi-controlled areas, to clearly casting the conflict as being about Yemen’s sovereignty over its airspace, ports, and territorial waters. Nagi concluded, “By taking direct action to reassert this view, the Houthis have raised the political stakes and made future compromise considerably more difficult.” Yasmeen al-Eryani, an analyst at the Sana’a Center for Strategic Studies, characterized the Mahan Air flight saga as part of Iran’s escalation of the war. She suggested, “By activating the Yemeni front, Tehran reiterates the strategic value of that pressure lever and signals that attacks on Iran can produce costs elsewhere, particularly for Saudi Arabia and the Gulf.”
