Houthis Seize Bab el-Mandeb Coast as Saudi Pipeline Burns—Can Iran’s Allies Squeeze Both Oil Gateways?
Ansarallah’s capture of Mocha, Dhubab and Mayun Island gives it unprecedented leverage over Bab el-Mandeb as satellite imagery confirms smoke along Saudi Arabia’s East–West pipeline. But threatening a strait is not the same as controlling every ship that crosses it.
Ansarallah has captured Mocha, Dhubab and Mayun Island in a rapid offensive that places the movement across the Yemeni side of Bab el-Mandeb. At the same time, satellite imagery shows a major smoke plume along Saudi Arabia's East–West oil pipeline, which Riyadh has shut for safety checks after drone attacks. Together, the developments create the most serious threat in years to the routes connecting Gulf energy with global markets.
The territorial advance is no longer only a social-media claim. Reuters, the Associated Press and other outlets confirmed the Houthi arrival on Mayun—also called Perim—after government forces withdrew. The island divides Bab el-Mandeb into two channels. Control provides an exceptional location for observation, radar, drones, missiles or mines.
Reports also describe Houthi gains on other Red Sea islands and across coastal villages. If sustained, this would eliminate most remaining anti-Houthi footholds along Yemen's western shore. The collapse reflects not only Ansarallah's military strength but fragmentation among forces aligned with the Presidential Leadership Council.
The phrase “Houthis control Yemen's Red Sea coastline” needs geographic precision. Ansarallah already held large northern coastal areas around Hodeidah and has now taken key southern stretches near Mocha and the strait. Some islands, isolated units and coastal zones may remain contested. Front lines can change faster than maps are verified.
More importantly, controlling the Yemeni shore is not identical to controlling international navigation. Bab el-Mandeb has an African side, international transit rights and foreign naval forces nearby. Commercial tracking still shows ships crossing. Ansarallah can impose severe risk, selectively target vessels and raise insurance costs without being able to inspect or stop every ship.
That distinction does not make the threat small. A mobile missile team needs only occasional access to the coast. Mines can close lanes until surveyed. Even unsuccessful attacks compel escorts and rerouting. Shipping companies make decisions based on probability and liability, not on whether a militant group holds a legally recognized customs post.
The Saudi pipeline crisis magnifies the effect. Petroline moves crude from the kingdom's eastern fields to Yanbu on the Red Sea, bypassing the disrupted Strait of Hormuz. Saudi Arabia confirmed multiple drones from Iraqi territory struck the system in the Riyadh and Medina regions, causing injuries and damage. It shut the pipeline as a precaution.
Satellite pictures establish fire and smoke, not the precise equipment destroyed. Pump stations, transformers, storage or the main pipe could be affected differently. Only throughput data and repairs will reveal the true loss. Yet markets must price the possibility that Saudi Arabia's alternative route is limited precisely when the Gulf route is unreliable.
Iran benefits strategically from simultaneous pressure but does not automatically command every Houthi decision. Tehran arms and supports Ansarallah, while the Yemeni movement has its own leadership, local grievances and negotiating objectives. Shared interests can produce coordinated timing without proving a direct order for each advance or attack.
The humanitarian cost is immediate. International organizations report tens of thousands displaced and hundreds killed during the renewed offensive. Mocha and surrounding districts contain civilians who had already survived years of war. A Saudi-PLC counterattack or foreign strikes on island positions could produce another mass flight.
Ansarallah says navigation is safe except for Saudi vessels. Shipowners will not accept that assurance at face value because targeting criteria can change and identification errors occur. A declared selective embargo still violates normal expectations of free passage and exposes neutral crews.
Saudi Arabia now faces three options: counterattack, negotiate or attempt both. Airpower may hit fixed positions but cannot guarantee removal of dispersed coastal weapons. Local allies may retake territory if they coordinate, though recent withdrawals show serious political weakness. Talks could reduce attacks but may consolidate Houthi gains.
International navies also confront a mission problem. Escorting ships protects individual voyages; clearing islands or mainland launch zones would require offensive operations and risk a wider war. Deterrence depends on whether Ansarallah believes the economic leverage of disruption exceeds the cost of retaliation.
Market language can run ahead of reality. “Both straits are closed” is not supported while vessels transit. “Nothing has changed” is equally wrong when one group can threaten a chokepoint from new positions and a major pipeline is offline. The accurate description is a layered supply crisis in which physical flow continues under shrinking margins of safety.
What to watch next
Watch geolocated Houthi deployments on Mayun, anti-ship systems, mine warnings, ship transits and insurance notices. Does Saudi Arabia restore pipeline flow, launch a counteroffensive or seek a ceasefire? Can the PLC hold Taiz and Aden? Ansarallah has captured strategic terrain—but will it use that terrain to close Bab el-Mandeb, collect political leverage, or discover that holding a narrow strait invites overwhelming international pressure?
