Who Are the Houthis? The Armed Movement That Shut Down Saudi Arabia’s Capital Airport (October 14, 2026 Update)

A ballistic missile struck the international airport in Riyadh. Among the dead were passengers waiting at the gate for a pilgrimage flight. In October 2026, the attacks by the Yemeni armed movement known as the Houthis entered a phase without precedent in eleven years of war.

Most coverage disposes of them in a single phrase: an Iran-backed militia. That phrase explains nothing. It does not tell you who these people are, where they came from, or how a movement with no air force is able to strike the country that guards the two holiest sites in Islam.

This article breaks the movement down across eight dimensions, using international reporting and specialist research. The final section explains why this war is already reaching households in Japan and across Asia.

1. The latest: a capital with its airport closed

🟢 Between October 6 and 12, 2026, the Houthis launched a sustained campaign of ballistic missile and drone attacks against three airports inside Saudi Arabia, in Riyadh, Abha and Dammam. At least 20 people were killed and more than 370 wounded.

🟢 The deadliest strike came on October 10 at King Khalid International Airport in the capital. According to reporting by Al Jazeera and the Washington Post, that single attack killed twelve to thirteen people and wounded more than 300. The dead included a Saudia pilot, a flight attendant, and passengers preparing to depart on Umrah, the lesser pilgrimage. One American citizen was among those killed.

🟢 The airport was closed, and the Saudi General Authority of Civil Aviation extended that closure through October 17. For the main aviation gateway of the capital to stay shut for more than a week is extraordinary in Saudi Arabia.

🟡 Houthi military spokesman Yahya Saree warned international carriers that flights into Saudi airports were unsafe. He carved out one exception: flights serving Mecca and Medina. Why that exception exists is the subject of section four.

October timeline

🟡 Coalition spokesman Turki al-Maliki called the October 10 strike a full-fledged war crime and a cowardly terrorist attack, pledging a decisive response under customary international humanitarian law. The Saudi cabinet, chaired by Crown Prince Mohammed bin Salman, said the Houthis would face consequences.

🟢 Iran, meanwhile, offered to mediate between its own allies and Saudi Arabia. The irony was not lost on anyone.

2. Origins: from a study circle to a regional military force

🟢 The movement's formal name is Ansar Allah, meaning the supporters of God. Houthi is simply the family name of its founder, used as shorthand by outsiders.

🟢 It began in the early 1990s in Saada province, in the mountains of northern Yemen. This is the heartland of Zaydism, a branch of Shia Islam whose imams ruled northern Yemen for roughly a thousand years until the revolution of 1962 swept the dynasty away. In the decades that followed, Zaydi religious tradition was pushed steadily to the margins.

🟢 The response was the Believing Youth, in Arabic al-Shabab al-Mumin. It ran schools, study groups and summer camps to teach Zaydi doctrine to a younger generation. It was a religious revival movement, not an armed one.

🟢 Its central figure was Hussein Badreddin al-Houthi, born in 1959, who served in Yemen's parliament from 1993 to 1997 and had studied under clerics in the Iranian city of Qom.

🟢 On January 17, 2002, at the Imam al-Hadi school in Marran, Hussein introduced a slogan borrowed from the Iranian revolution and had those present chant it. Arab News describes this as the decisive turn in the movement's character.

🟢 In 2004, the government of Ali Abdullah Saleh moved to arrest him, badly underestimating his support base. Fighting broke out across Saada, and in September of that year Hussein was killed by government forces.

🟢 Between 2004 and 2010 the Houthis fought six rounds of war against the Yemeni state, known collectively as the Saada wars. Those six years produced a battle-hardened force.

🟢 When the Arab Spring brought down Saleh's thirty-three-year rule in 2011, the Houthis took all of Saada province. In September 2014 they seized the capital, Sanaa. On March 26, 2015, a Saudi-led coalition intervened with Operation Decisive Storm. Eleven years later, that war has not ended.

3. Scale: how a force with no air force trades fire with a wealthy state

🟡 Manpower estimates vary enormously. Older figures put the movement at around 100,000 fighters, while a Forbes analysis published on October 11, 2026 cites 350,000. The honest answer is that nobody has a reliable count.

🟡 On weapons, open-source compilations identify roughly 116 distinct named systems the Houthis have publicly displayed, including about 25 surface-to-surface missiles, 13 anti-ship missiles, 10 surface-to-air missiles, 16 drone types and 19 naval weapons.

🟡 Wolf-Christian Paes, a senior fellow at the International Institute for Strategic Studies, has summarized the intelligence problem bluntly: the group could hold one missile of a given type or a hundred, and nobody knows until they are fired. Weapons developed and smuggled covertly cannot be inventoried from outside.

Why Saudi air defenses are being penetrated

🟡 Security analyst Wolfgang Pusztai told Al Jazeera that the Saudi ballistic missile defense architecture was built primarily against a threat from Iran. Saturation attacks arriving from the south were never the design case.

🔵 Then there is geography. Saudi Arabia covers roughly 2.2 million square kilometers. No shield covers all of it at once, at any price. The Houthis compound the problem by launching drones and missiles of different speeds in the same wave, complicating detection and interception. They do not need to get through every time. They need to get through once.

4. Why attack the country that guards the holy cities?

This is the question most coverage skips. How does a Muslim movement justify striking the state that administers Mecca and Medina? The answer has four layers.

Layer one: eleven years of retaliation

🟢 Since 2015, the coalition air campaign has been linked by international bodies to one of the worst humanitarian emergencies in the world. To the Houthis, Saudi Arabia is not primarily the custodian of holy sites. It is the state that has bombed them for eleven years.

Layer two: siege for siege

🟡 Houthi military statements describe the policy as upholding the equation of siege for siege until the aggression stops and the blockade is lifted. Sanaa and Hodeidah airports are blockaded and bombed, so Saudi airports are to suffer the same fate. The logic is crude and entirely legible.

🟢 Al Jazeera's correspondent in Sanaa, Yousef Mawry, reported that the movement intends to impose a blockade on every Saudi airport. In June 2026 the Houthis announced a new phase in the confrontation, centered on lifting the blockade of their own air and sea ports.

Layer three: the holy cities are deliberately excluded

Layer four: the economy as the real target

🟢 Airports are not the only targets. Saudi oil infrastructure has been struck repeatedly, including a blaze at an Aramco facility south of Riyadh on October 3.

🔵 These are not military objectives. They are an attack on Vision 2030, the Crown Prince's plan to pivot the kingdom away from oil toward tourism and technology investment. That plan rests entirely on an image of safety. Tourists and investors do not go where missiles land on runways. The Houthis are not shooting at tanks. They are shooting at a national brand.

5. The relationship with Iran: proxy or partner?

🟢 Iranian supply of weapons and technology is well documented. Conflict Armament Research has conducted field investigations in Yemen and the Gulf since 2016, and its component-level analysis of seized materiel has identified numerous Iranian-origin missile parts in Houthi hands.

🟡 Nawaf Obaid, a senior fellow in the war studies department at King's College London, assesses that the Houthi missile inventory is essentially derived from Iranian weaponry, with some Chinese technological influence.

🟢 One episode captures the dynamic. On July 13, 2026, a Mahan Air flight carrying commanders of Iran's Islamic Revolutionary Guard Corps along with weapons attempted to land at Sanaa airport. Yemeni government forces and Saudi Arabia bombed the runway to stop it. That incident became one of the triggers for the current escalation.

But they are not a puppet

🔵 Here the standard shorthand breaks down. Calling the Houthis an Iran-backed militia and stopping there flattens something more complicated.

🟢 The evidence is their separate track with Washington. The Houthis met American officials in Oman and made clear their war was with Saudi Arabia alone, which has allowed American vessels to transit the Red Sea freely. While Iran confronts the United States directly, the Houthis are running their own calculation.

🔵 So the movement is a member of Iran's axis of resistance that nonetheless retains its own decision-making machinery and its own objectives. The weapons come from Tehran. The decision to fire is made in Sanaa. Miss that distinction and you will misread what comes next.

6. Sunni and Shia: the structure behind the shorthand

Plenty of explainers call this a sectarian war. That is only half true, and the half that is false matters.

The split began in 632

When the Prophet Muhammad died without naming a successor, the community divided. One camp held that leadership should be decided by consensus, and became the Sunnis. The other held that authority belonged to Ali and his descendants, the Prophet's bloodline, and became the Shia. A political succession dispute grew, across fourteen centuries, into a theological and cultural divide.

Zaydism is the exception that breaks the frame

🔵 What is actually at work is geopolitics. Two regional powers, Saudi Arabia and Iran, compete for influence through third countries, and sect supplies the vocabulary of recruitment and justification. The same pattern has played out in Yemen, Syria, Lebanon and Iraq.

7. What Western analysts expect next

Specialists quoted in international media are genuinely split. The main positions are below.

Branch point one: will Saudi Arabia send in ground forces?

🟢 For now, Riyadh is supplying air power to anti-Houthi Yemeni government forces and has stopped short of committing its own troops at scale.

🔵 The reasons are obvious. A ground campaign across Yemen's mountains would be expensive and open-ended. More damaging still, it would destroy the image the Crown Prince has spent years constructing, of a stable, investment-friendly destination. The moment Saudi boots cross the border at scale, Vision 2030 is effectively frozen.

Branch point two: will Washington enter the war?

🟢 The death of an American citizen at Riyadh airport changes the political arithmetic. Secretary of State Marco Rubio called for an end to the attacks, and President Trump said the United States was evaluating whether to join the Saudi offensive against the Houthis.

🟡 According to reporting by Cable News Network, more than 100 American military advisers were deployed to Saudi Arabia weeks earlier, after signs that Iran was increasing its support to the Houthis, and are providing intelligence support to Saudi forces.

Branch point three: any thaw between Washington and Tehran?

🟡 Nagi of the International Crisis Group argues that one of the key drivers behind the current Houthi escalation is the confrontation between the United States and Iran, and that de-escalation between those two would remove it. The inverse also holds: while the wider Iran war continues, the Yemen front will not settle on its own.

8. Why this reaches Asia: three channels

Yemen is some 9,000 kilometers from Tokyo. Few advanced economies are more exposed to this war than Japan, and the mechanism is instructive for any oil-importing nation.

Channel one: crude

🟢 Japan imports nearly all of its energy, and its crude dependence on the Middle East has run above 90 percent for years. In the first quarter of 2026, Saudi Arabia alone supplied more than half of Japanese crude imports.

🟢 After the Iran war disrupted the Strait of Hormuz, that regional dependence fell sharply, from 94.2 percent to 73.9 percent. Read the underlying statistics, though, and this is not the fruit of planned diversification. It is emergency rerouting.

Channel two: the Red Sea detour is itself under the gun

🟢 When Hormuz became difficult, Saudi Arabia leaned on Yanbu, its terminal on the Red Sea coast, piping crude westward and exporting it from there. That workaround has been holding up a meaningful slice of global supply.

🟢 Then the Houthis seized the Red Sea coast in 2026, taking Mokha and Perim Island at the mouth of the Bab el-Mandeb Strait. Tankers near Yanbu have been reported to sit within Houthi strike range. A weapon now sits at the exit of the detour.

🟢 In normal times the Red Sea corridor carries roughly 30 percent of global container traffic and about 12 percent of world trade, worth around one trillion dollars a year. Routing around the Cape of Good Hope adds days and cost, and that cost arrives in import prices.

Channel three: there is already a precedent

Conclusion: what the shorthand conceals

🔵 Iran did not create the Houthis. They emerged as a religious revival in the mountains, were militarized by a government crackdown, were tempered by eleven years of war, and then acquired, through Iranian weapons, the ability to strike a regional power. Tehran did not build them. Tehran began backing them once they were useful.

🔵 And with no air force and no navy worth the name, they have closed the main airport of a country with one of the world's largest defense budgets for over a week, and trained their weapons on the detour that global oil supply is currently using. This is a live demonstration of how far asymmetric warfare can push a state.

🔵 The convenient phrase, Iran-backed militia, buries all of that. And when it is buried, readers never learn why fuel prices move or why shipments arrive late. The real danger is not a missile in a distant country. It is the missing explanation of how that country is wired to your own.
