Houthi forces capture Yemeni port city of Mocha and advance toward Bab al-Mandab strait

Fall of the Red Sea port

Houthi forces captured the port city of Mocha on Yemen's western coast following sustained artillery and rocket bombardment, culminating on Wednesday evening, 9 September 2026, at approximately 20:00 local time. Defensive lines disintegrated as elite government units and Saudi military advisers withdrew from the city, followed by regular Yemeni army personnel. Eyewitnesses reported that Houthi fighters entered Mocha chanting slogans, established checkpoints at major road intersections, and closed transit corridors connecting the coast to the interior. Local commercial shops shuttered across the city as armed patrols deployed across public squares. Mocha had served as the final Red Sea port under the control of the internationally recognized government since the outbreak of the wider conflict in 2015, when the Houthis seized the capital Sanaa.

Farea al-Muslimi, a research fellow and Yemen expert at Chatham House, evaluated the development:

The fall of Mocha is therefore a geopolitical earthquake.

Retreat to Dhubab and island operations

Following their withdrawal from Mocha, Yemeni government forces and allied units retreated south along the coastline toward Dhubab to regroup. Dhubab is situated directly opposite Perim Island, placing it in a position to command access to the Bab al-Mandab strait, located between 70 and 80 kilometers south of Mocha. The loss of the port followed Houthi advances into the Al-Shaqira district, an operation that severed vital supply routes linking the coastal front with the provincial capital of Taiz. In conjunction with their coastal ground offensive, Houthi fighters seized Zuqar Island in the southern Red Sea and launched assaults against the nearby Hanish Islands.

Chokepoint pressure on the Bab al-Mandab

The territorial shift gives Houthi forces direct geographic proximity to the Bab al-Mandab strait, the maritime corridor linking the Red Sea to the Gulf of Aden and the Indian Ocean. At its narrowest point, the strait spans approximately 20 kilometers, compared to roughly 50 kilometers for the Strait of Hormuz. Defense analyst Wolfgang Pusztai told Al Jazeera that controlling this coastline enables the Houthis to target commercial vessels with land-based artillery, reducing their reliance on anti-ship missiles and unmanned aerial drones. Umer Karim, a Gulf defense specialist at the University of Birmingham, told the Wall Street Journal that the capture represents a severe setback for the National Resistance forces and the Saudi-led coalition, expanding Houthi leverage over oil and cargo transit between Europe and Asia.

Regional fallout and coalition fragmentation

The capture of Mocha threatens vital entry points for humanitarian aid into Yemen, where more than 40 million residents face food insecurity following years of conflict that caused roughly 150,000 deaths. The battle follows the breakdown of a ceasefire established in 2022. The anti-Houthi coalition, which includes National Resistance forces led by Tareq Saleh, has suffered from internal divisions among tribal groups, Islamists, and southern separatists. Yemen analyst Nadwa Dausari noted that Iran utilizes its alliance with the Houthis as bargaining leverage in the broader regional war. Tensions mounted after the Houthis declared a naval blockade against Saudi Arabia in late July 2026, attacking commercial oil tankers. In response to strikes targeting US installations in Kuwait, Jordan, and Bahrain, US Defense Secretary Pete Hegseth ordered extensions for American troop deployments across the region.
