Why the Siege of Taiz Changes Everything in Yemen

Taiz is falling again — and the implications go far beyond Yemen

Taiz, Yemen’s third-largest city, has been under siege before. Between 2015 and 2017, the Houthis tried to swallow it. They failed. Now they have surrounded it once more, and the humanitarian calculus is stark: the World Food Programme says it cannot reach more than 600,000 people trapped inside and around the city. Over 200,000 have already fled since the Houthi offensive along the Red Sea coast began in September.

But this is not simply a replay. Taiz sits at the geographic hinge between the Red Sea littoral and the southern highlands where Aden — the administrative capital of Yemen’s internationally recognized government — shelters. If the Houthis tighten their ring around Taiz’s surrounding mountains, they cut the land corridor that any southern counteroffensive must rely on. That is why the city matters far beyond its own borders.

The counteroffensive that stalled

President Rashad al-Alimi — a native of the Taiz governorate — announced Operation Dawn of Yemen on October 5. Its stated aim was sweeping: drive the Houthis out of the whole country, Sana’a included. Two weeks later, the operation has stalled.

Government forces, flying under heavy Saudi air cover, have recaptured some ground around Bab al-Mandab and Dhubab. But Mokha, the coastal prize the Houthis seized in September, remains firmly in their hands. Worse, the government coalition is fracturing. When the western coast collapsed in September, Tareq Saleh — who commands the National Resistance Forces that held it — withdrew south to Aden. Southern units initially refused his troops entry, wary of a repetition of 1994, when northern forces crushed the south’s bid for independence. The man who led that assault was Saleh’s uncle, then President Ali Abdallah Saleh.

The Houthis, by contrast, hold contiguous territory. They can shift forces and materiel between fronts with relative ease. Their opponents answer to different commanders with different political projects, fighting under a single banner that barely holds together.

The Saudi dilemma

Riyadh’s response has been aggressive in substance but carefully restrained in tone. The kingdom has carried out waves of air and missile strikes on Houthi territory. It has not, however, named Iran — the movement’s primary patron — as the enemy. That reticence is deliberate. Riyadh is preserving room for a possible deal between Washington and Tehran that could reopen the Strait of Hormuz and, ideally, end the attacks on Saudi soil that have intensified since July.

The costs of those attacks are mounting. King Khalid International Airport in Riyadh has been struck multiple times this month, killing 13 and wounding more than 300. Last week, the Houthis hit Aramco’s headquarters in Dhahran, with fire spreading across several floors. Reuters estimates Saudi crude output ran below 7 million barrels a day for most of the first six months of the wider U.S.-Iran conflict, representing roughly $50 billion in lost revenue at current prices. The IMF expects the Saudi economy to shrink by 3.3 percent this year.

Regional allies have activated the Mecca Joint Defence Agreement. Turkey and Pakistan have committed, but both describe their roles as strictly defensive. Egypt’s President Abdel Fatah al-Sisi asked parliament for authority to support the kingdom militarily, stressing that the conversation is about defense alone. Donald Trump called the Houthis “behaving very badly” and suggested Turkey might be asked to do more. But with midterm elections on November 3 and an eight-month war that has produced no settlement, the White House has zero appetite for another campaign in Yemen.

Riyadh, short of options, has offered no comprehensive strategy beyond punitive airstrikes and support for a counteroffensive that is faltering. The siege of Taiz is the clearest evidence of that failure.

Who is the Houthi project, really?

There is a growing debate in Saudi policy circles about whether the Houthis should be negotiated with, as other actors in the region have been. Abdulrahman al-Rashed, a former editor of Asharq al-Awsat and a well-connected commentator, has argued forcefully against accommodation. The Houthi project, he wrote, is “fundamentally at odds with the very idea of the state.” Concessions and pauses, he noted, have only been used to re-arm and resume fighting. “They are yet another Iranian proxy in the region, not the nucleus of an ordinary Yemeni system of government.”

Crown Prince Mohammed bin Salman appears to share that assessment. On October 13, chairing the cabinet, he declared that the “terrorist Houthi militia will face the consequences of its heinous crimes and attacks.”

Tehran, meanwhile, plays a contradictory game. Foreign Ministry spokesman Esmail Baghaei says Iran will mediate if both sides ask and denies any role in Yemeni operations. Yet investigative reporting has repeatedly demonstrated that Iranian advisers and intelligence actively enabled the Houthi capture of Yemen’s Red Sea coast. Iran’s hardline press celebrates the strikes on Saudi airports and oil facilities. Kayhan, whose editor-in-chief is selected by the supreme leader, refers to the Houthis as “Yemen’s armed forces” and frames the conflict as a “twelve-year aggression of the Saudi-American coalition.” An adviser to the parliamentary speaker, one of Iran’s key negotiators with the United States, wrote that Tehran would use “tools in the Strait of Hormuz, Bab al-Mandeb and beyond” to keep oil prices elevated.

The mediation trap

When Iran offered to mediate, Yemen’s foreign minister, Afrah al-Zouba, rejected it outright, calling Iran a “party to the war against the Yemeni people.” The rejection was predictable given Tehran’s framing of events. But it also exposes a structural problem: Iran has arrived at the table with its position already fixed. It calls the Houthis Yemen’s legitimate armed forces. It describes Saudi restrictions on flights and ports in Houthi-held territory as a “blockade,” when Riyadh sees them as enforcement of a U.N.-backed arms embargo in support of the recognized government.

Any move by Saudi Arabia toward negotiation would look like a concession to that framing. That makes talks harder for Riyadh even if it wanted them — and there is little sign that it does. The question now is what happens next if Taiz falls.

The city has symbolic weight disproportionate to its size. Its poets and journalists supplied much of the dissident energy that toppled the Imamate in 1962. Its streets were a center of the 2011 uprising against Saleh. Taiz has resisted Houthi encroachment for a decade. If that resistance breaks, the message to every faction that still opposes the Houthis will be unmistakable: the window for holding ground is closing.

For Saudi Arabia, the alternative — deeper military involvement — carries risks it has spent months trying to avoid. Escalating into Yemen while already entangled in a wider confrontation with Iran could drag the kingdom into a conflict it has no clear exit from. The current strategy of airstrikes and proxy support is producing diminishing returns. Taiz is the proof.

The Houthis set the tempo. Riyadh reacts. That dynamic will continue until someone changes it — and neither Washington nor Riyadh shows any sign of wanting to pay the price.
