Houthis tighten their grip on the Red Sea's southern gate

The Houthis have gone island-hopping, and the Red Sea just got narrower.

Houthi officials said on Monday, September 14, that they had seized Greater and Lesser Hanish — two strategic islands in the southern Red Sea, bolstering their control over one of the world's key shipping routes.

The Hanish islands sit near the Bab el-Mandeb — the strait's southern gate, where the Red Sea funnels into the Gulf of Aden and every tanker bound for Suez must pass.

The name on the chart is older than the war. Bab el-Mandeb means the Gate of Tears — or the Gate of Grief — named for the sailors the strait's currents and reefs have claimed across the centuries. At its narrowest, barely twenty miles of water separate Arabia from Africa, split by the volcanic rock of Mayun island into two channels. Every empire that wanted the Red Sea has wanted this gate: the Ottomans, the British, and now a rebel movement from Yemen's highlands that has learned to think like a navy without owning a single warship.

The Hanish islands have been fought over before. In 1995, Yemen and Eritrea went to war over them — a short, sharp conflict over rocks that command the southern Red Sea's shipping lanes — and an international tribunal later awarded the islands to Yemen. The lesson of that war was the one the Houthis have now absorbed: in these waters, the islands are the strategy. Who holds the rocks holds the route.

Three days earlier, on September 11, the rebels captured Mayun island — the tiny volcanic rock sitting directly in the Bab el-Mandeb's mouth, commanding the narrows themselves.

On September 10, they took Mokha, the Red Sea port. A port, an island, two islands: a week of advances in a war that usually measures progress in years.

Mokha's name carries its own history. This is the port that gave the world mocha — the coffee shipped from these docks for centuries made the town's name a synonym for the drink across the globe. The Houthis did not take Mokha for its coffee. They took it because a port at the strait's edge is a logistics node: boats, fuel, men, and a runway whose status is now contested. History made Mokha famous. Geography has made it strategic again.

The pattern is unmistakable. These are not raids. This is a siege of a waterway — positions taken and held around the choke point, one basalt rock at a time.

These are not raids. This is a siege of a waterway — positions taken and held around the choke point.

About 12 percent of the world's goods are typically shipped through the Bab el-Mandeb at the Red Sea's southern end — the number every logistics manager on earth has memorized this year.

The 12 percent is not an abstraction. It is container ships full of electronics and garments, tankers full of crude and refined products, bulk carriers full of grain — the physical inventory of globalization, threaded through a twenty-mile gap. The world learned this number the hard way: when the Houthis began attacking merchant shipping in late 2023, in the wake of the Gaza war, the strait became a war-risk zone overnight, insurance rates exploded, and the great shipping lines rerouted around Africa. The 12 percent kept moving — but it moved the long way, and the bill landed on every consumer on earth.

The context is Hormuz. With the strait to the east burning, Saudi Arabia's oil exports depend increasingly on the Red Sea route to the west — the very corridor the Houthis are now tightening.

The Saudi geometry is the story's hidden engine. The kingdom's great oil fields face east, toward the Gulf and Hormuz; its great alternative faces west, toward the Red Sea — the east-west pipeline to the port of Yanbu, built precisely so Saudi crude could reach the world without passing through Hormuz. That alternative only works if the Red Sea is open. With Hormuz constricted and the Bab el-Mandeb tightening in Houthi hands, Riyadh faces the scenario its planners built the pipeline to avoid: both gates contested at once. The two-front naval puzzle is not a metaphor. It is a map.

Mayun island matters disproportionately to its size. A few square kilometers of basalt, commanding the narrows where every tanker to Suez must thread the needle.

The Hanish islands are no better positioned — for the ships, that is. For the Houthis, the geography is a gift: fixed ground in the middle of moving water.

Fixed ground changes the kind of war this is. Drones and missiles harass shipping; islands command it. A radar on Mayun sees every hull that threads the narrows. A battery on Greater Hanish reaches across the southern approaches. The Houthis spent the last years proving they could hit ships from the shore. The September advance is the move from harassment to ownership — from taxing the waterway to holding it. That is the grammar shift the article's closing names: from drones to territory. Watch the water, not the sky.

Beijing is watching — and buying. China, a major Middle East oil importer, said on September 14 that it was "deeply concerned," calling Houthi attacks on Saudi energy infrastructure "unacceptable."

That word — "unacceptable" — is diplomat-speak for "we are not neutral anymore," or at least "we would like you to think we are not." China buys the oil that sails past these islands; its patience has a price, and the price is measured in barrels.

China's stake is physical, not rhetorical. The world's largest oil importer buys heavily from the Gulf, and much of it sails through the straits now contested — Hormuz to the east, Bab el-Mandeb to the south. Beijing even keeps a naval facility in Djibouti, a short sail from Mayun, the only overseas base it operates. When the foreign ministry calls attacks on Saudi energy infrastructure "unacceptable," it is speaking as a customer whose supply line runs through a war zone. Whether the word comes with consequences — pressure on Tehran, which arms the Houthis, or a harder line at the UN — is the question the consensus leaves open. But the customer has now spoken, on the record, in September.

Riyadh may have answered with steel — or may not have answered at all. A Houthi broadcaster claimed Saudi airstrikes hit the airport in Mokha within hours of the advance; AP carried the claim but could not confirm it, reported no damage or deaths, and Riyadh stayed silent.

The silence is the Saudi way, and the airstrike claim is the war's oldest fog. Riyadh has spent a decade bombing Yemen from the air — the air campaign that began in 2015 never truly ended — and the one currency it can spend quickly is airpower against fixed positions. But a decade of airpower is also the Houthis' education: the movement learned to disperse, to dig, to survive the sky. The Western analysts' question is the right one — whether airpower can dislodge a force that has spent ten years surviving it. The islands sit under the same sky the Houthis have lived under since 2015. They know its moods.

Iran, meanwhile, called on Saudi Arabia to end its blockade of Yemen and return to negotiations — a statement that reads differently depending on who you believe arms the Houthis.

The Iranian statement is doing two jobs at once. Read straight, it is diplomacy: end the blockade, return to the table, the waterway's future is negotiated, not bombed. Read with the other eye — the one that tracks the missiles' provenance — it is the patron urging restraint on the adversary while its client advances on the ground. Both readings can be true. That is the nature of this war's diplomacy: every call for negotiations is also a move on the board.

The Red Sea is now a two-front naval puzzle: the Bab el-Mandeb tightening in the south, Hormuz constricted in the east. Two gates, both contested, both burning.

For Egypt, the stakes are existential-adjacent: Suez Canal revenues depend on traffic that must pass the very islands the Houthis now hold. Cairo's budget has a line item riding on the Hanish islands.

The line item is hard currency — the kind Egypt's economy runs on. Suez Canal tolls are among the country's largest sources of foreign exchange, the dollars that pay for wheat imports and steady the pound. When traffic reroutes around the Cape, the tolls evaporate; when the Houthis hold the islands the traffic must pass, Cairo's revenue depends on a rebel movement's goodwill. That is the "existential-adjacent" arithmetic: not survival, but the slow bleed of the treasury, measured in transits that never come.

For Europe's supply chains, the detour math is brutal: around the Cape of Good Hope adds weeks to a voyage and millions in fuel and freight — a tax the Houthis collect without owning a single ship.

The detour's cruelty compounds. Weeks added to a voyage are not just fuel — they are inventory sitting on water instead of on shelves, container boxes stranded in the wrong ocean, schedules rewritten across every port in the rotation. The freight rates spike first; the consumer prices follow months later, laundered through a dozen intermediaries until no label says "Red Sea." The Houthis collect the tax without owning a ship, without firing a shot at most hulls — the threat alone reprices the route. That is the economics of the siege: control does not require sinking. It requires being believed.

The Houthis' calculation is plain arithmetic: control the gates, set the terms. A rebel movement with islands is a rebel movement with a navy made of geography.

Whether they can hold what they took is the open question. Islands are also traps — fixed, exposed, reachable by airpower and blockade. The Houthis claim Mokha's airport already lies in rubble; the claim is unverified, but the vulnerability it points to is real.

The trap logic cuts both ways. An island cannot retreat; a garrison cannot melt into the highlands the way Houthi fighters have done for a decade. Resupply runs across open water, under skies the Saudis own. Eritrea sits across the strait, a wary neighbor with its own history on these rocks. The Houthis have taken the high ground of the waterway — and high ground, in a war of airpower, is also a target. The September advance proved they can seize. The months ahead will test whether they can keep.

Airpower punishes fixed positions; the Houthis learned that lesson a decade ago, and the Hanish islands sit under the same sky.

The week that was: a port, an island, two islands. The war's grammar is shifting from drones to territory. Watch the water, not the sky.

Western coverage — AP, the Institute for the Study of War — frames the week as a deliberate escalation: the Houthis moving from harassing shipping to occupying the waterway itself, island by island.

The emphasis is on the sequencing — Mokha on the 24th, Mayun on the 25th, the Hanish islands on the 28th — read as a campaign, not a coincidence. The ISW's mapping instinct treats each seizure as a data point in a tightening perimeter.

The reported Saudi airstrikes — claimed so far only by Houthi media, unconfirmed by AP — are covered as the predictable response: airpower against fixed positions, the one currency Riyadh can spend quickly. The question Western analysts ask is whether airpower can dislodge a force that has spent a decade surviving it.

The risk, in this reading, is a southern Red Sea under effective Houthi control — a second Hormuz, built one island at a time.

The Western lens also reads the campaign as a message to Washington. The Houthis are demonstrating, island by island, that the waterway's security cannot be restored by naval patrols alone — that the era of swatting drones from destroyers has given way to an adversary that holds ground. In this telling, the September advance raises the price of every future negotiation: the islands are now chips on the table, and chips get traded, not surrendered.

Eastern coverage centers on Beijing's reaction: China's "deeply concerned" and "unacceptable" are given unusual weight, read as a signal that the world's largest oil importer is losing patience with the Red Sea's instability.

Iran's call for Saudi Arabia to end the Yemen blockade and return to negotiations is covered straight — as diplomacy, not deflection. The blockade, in this telling, is the original siege; the islands are the answer.

The emphasis falls on negotiation as the only exit: airstrikes failed for a decade, the argument runs, and will fail for another. The waterway's future is a table, not a target.

The risk, in this reading, is escalation by airpower — that Riyadh's airpower widens a war diplomacy could still close.

The Eastern lens also weighs China's word against China's interests. Beijing's "unacceptable" is read as the moment the customer becomes a stakeholder — the oil importer's patience expiring in public. In this telling, the question is whether the word travels to Tehran: China buys Iranian oil too, and the patron's leverage over its client is the one channel that might still move the Houthis. The East watches Beijing not for what it says about the islands, but for what it says to Iran about them.

The South — Yemeni outlets like 26SepNews among them — reads the week through the blockade's long shadow. Yemen has lived under siege conditions for years; the islands are, in this telling, the besieged pushing back.

Coverage emphasizes the human geography: Mokha is a port city with people in it, the Hanish islands have fishermen, and every airstrike has an address. The war's abstractions — "choke points," "corridors" — land on real roofs.

The 12-percent figure gets the South's full attention: the world's goods, the world's food, the world's fuel — all passing through a strait the great powers treat as a chessboard and the littoral states treat as a lifeline.

The risk, in this reading, is that the waterway becomes a permanent battlefield — and the countries that depend on it most have the least say in its fate.

The South's lens also refuses the chessboard. The fishermen of Hanish, the dockworkers of Mokha, the Yemenis who have lived under blockade for years — in this telling, the island seizures are not grand strategy but survival logic: the besieged securing the waters off their own coast. The great powers debate choke points; the littoral states live in them. The 12 percent of world goods is also 100 percent of somebody's fishing ground, somebody's port, somebody's roof. The abstractions land. They always land.

The stakes are the waterway — and the waterway is the world economy's throat. Two gates, both contested: Hormuz to the east, Bab el-Mandeb to the south, and between them the energy and the goods on which every economy runs. The Houthis have spent a week proving that a rebel movement can hold the throat with basalt and resolve. The months ahead will decide whether the throat stays held — whether airpower dislodges, whether Beijing's "unacceptable" acquires teeth, whether the table the East wants ever gets built. Until then, every tanker that threads the narrows sails through a siege, and every consumer on earth pays the tax. Watch the water, not the sky.
