**Deck**: Iran‑backed Houthi forces have seized the Yemeni port of Mokha and a swath of territory along the Red Sea, pushing Saudi‑backed units south and edging closer to the Bab al‑Mandab Strait. The gains threaten to turn one of the world’s key shipping lanes into an active front line again, with container crews, regional governments and energy markets all exposed.

Control of Yemen’s western coast is shifting fast, and with it, the risk calculus for one of the world’s narrowest maritime chokepoints.

Iran‑backed Houthi forces have captured the strategic port city of Mokha on Yemen’s Red Sea coast and are pressing south after Saudi‑aligned units withdrew, according to Yemeni officials and regional media on 10 September. Houthi‑affiliated outlets also say their fighters have taken Khukha from the north and Jabal al‑Nar from the east and are moving toward Yakhtil. A fighter linked to the group has filmed himself on the Mokha shoreline, claiming the city is now under Houthi control. These battlefield assertions align with a broader description from Yemeni sources that the Houthis have seized roughly 2,600 square kilometers in a rapid offensive launched on 4 September.

Mokha matters because of where it sits: less than 50 miles north of the Bab al‑Mandab Strait, the narrow passage that connects the Red Sea to the Gulf of Aden and on to the Indian Ocean. Modern global trade treats Bab al‑Mandab as a hinge. A significant share of Europe–Asia container traffic, fuel shipments and humanitarian supplies to the Horn of Africa passes through these waters. When a heavily armed faction tightens its grip on nearby shoreline and artillery‑range approaches, shipping firms, insurers and naval planners have to assume that routes, premiums and escort requirements may change.

On the ground, the offensive is reshaping the front lines that had been relatively static. A detailed field account says Ansarallah, the political‑military movement often called the Houthis, has pushed hard in Taiz and southern Hudayda governorates since 4 September, aiming to eliminate the internationally recognized government’s coastal salient and squeeze supply routes into the city of Taiz. South of Hudayda, the group is reported to have captured Khukha and advanced into Yakhtil from the north, while taking Jabal al‑Nar from the east. In Taiz’s Jabal Habashy district, Houthi units have taken multiple villages and heights and cut the Al‑Kadha–Al Makshah highway up to the outskirts of the Al‑Turbah–Taiz road, a vital artery for the city.

For civilians in these districts, the changes are not abstract. Front lines moving through Jabal Habashy, Mawza’a and around key crossroads such as Al‑Waziyah mean new checkpoints, disrupted food and fuel deliveries, and the risk that neighborhoods suddenly sit between rival artillery positions. Yemeni government forces, including units affiliated with the Presidential Leadership Council (PLC) and the Saudi‑backed Yemeni National Army (YNA), are reported to be retreating from some positions under pressure, particularly near the coast. The collapse of local defenses at Al‑Waziyah crossroad, triggered when Sanaa‑aligned troops took Al Uraysh in Mawza’a district, illustrates how quickly a logistical lifeline can become a vulnerability.

The Red Sea itself is now more exposed to the interplay between Iran’s regional ambitions and Saudi Arabia’s security concerns. Houthi control of Mokha gives the movement a port location closer to Bab al‑Mandab from which it could, in theory, stage anti‑ship missile launches, drone operations or small‑boat harassment. The group has previously targeted commercial vessels and naval ships in the Red Sea; their new positions shorten the distance and potentially complicate any future coalition maritime patrols trying to keep sea lanes open.

At the same time, not every front in Yemen is breaking the same way. On the Ad‑Dali axis, so‑called Giant Forces launched a new offensive into Al Bayda governorate but were forced to pull back to their starting lines after what are described as significant losses and unfavorable terrain. On the Al‑Jawf front, YNA units backed by Saudi air power tried to seize the Labinah camp outside Al‑Hazm and briefly took the town of Yatimah further north, only for Ansarallah to repel them and reassert control. The picture that emerges is of a Houthi movement on the offensive along the western coastal belt and in central highlands, while government‑aligned forces struggle to generate sustainable gains elsewhere.

For shipowners and energy traders, the key fact is that Bab al‑Mandab risk doesn’t require an outright blockade. It only takes credible threats close to shore to raise insurance costs, justify naval escorts and push some cargoes to longer, more expensive routes. Each additional kilometer of Houthi‑controlled coastline near the strait makes those conversations in shipping and underwriting offices less hypothetical.

The next signals to watch will be whether Houthi units consolidate in Mokha with visible deployment of coastal defense systems or drones, and how Saudi Arabia and its partners choose to respond. Renewed coalition airstrikes along the Red Sea coast, emergency maritime advisories from major flag states, or reports of diverted container and tanker traffic around the Cape of Good Hope would all indicate that this new phase of the Yemen war is starting to reshape global trade flows, not just Yemeni front lines.
