Houthis Warn US of 'Swift, Painful Response' If Washington Joins Saudi Strikes on Yemen
Track it live: Middle East war — live tracker
The Houthis warn US painful response message was delivered plainly. Mohammed Al Bukhaiti, a member of the Houthi political bureau, told AFP in an interview on Monday that if the US becomes involved in what he called aggression against Yemen, his movement would not stop to deliberate: there would, he said, be a swift and painful response targeting the United States and all its interests in the region. He also warned employees at Saudi oil facilities and airports to stay away from those sites, describing them as legitimate targets.
The warning landed on a day when the war again reached the Saudi capital. Explosions were heard over Riyadh on Monday night, the Saudi-led coalition said it had destroyed a ballistic missile fired by the Houthis toward the city, and the Houthis said they had once again targeted King Khalid International Airport. Later, the coalition announced in a statement on X that it had intercepted and destroyed two ballistic missiles launched toward Khamis Mushait, a city in southern Saudi Arabia near the border with Yemen that hosts a Saudi military base. CNN, tallying the day's statements, reported three missiles intercepted on Monday in total. No new casualties from Monday night's interceptions were reported in the wire coverage reviewed.
Why the warning came now: Trump is weighing US entry
Bukhaiti's interview was not delivered in a vacuum. After Saturday's strike on Riyadh airport — the deadliest of a week of attacks, which Saudi authorities said killed 12 people and wounded 309, with some later wire counts putting the dead at 13 as a wounded victim died — President Donald Trump said he was considering joining Saudi strikes against the Houthis, having previously rebuffed requests from Riyadh for direct US help. On Monday he returned to the subject, describing the Houthis in blunt terms as misbehaving badly, and said he would speak with Saudi Crown Prince Mohammed bin Salman. Secretary of State Marco Rubio has confirmed that an American citizen was among those killed on Saturday, calling the attacks reprehensible.
Saudi Arabia has reportedly requested Washington's help in dealing with the group as the attacks have continued. There has, so far, been no sign of US action: Reuters noted on Monday that despite Trump's statements there was no visible American strike activity, even as Saudi warplanes intensified their own campaign, including reported hits in Yemen's al-Jawf province.
A week that shut down a capital's airport
Monday's interceptions extended a sequence that has made Riyadh's airport — Saudi Arabia's second-busiest — the centre of the crisis. Houthi attacks on the airport began last week, killing six people between Tuesday and Thursday by Saudi official counts. Saturday's strike on a departure terminal killed at least 12 and wounded 309. A further attack on Sunday killed a Pakistani resident and wounded 11, and the Houthis said they also targeted King Fahd International Airport in Dammam on Sunday, an attack Saudi civil aviation authorities confirmed while assessing damage.
The practical consequences have compounded. Saudi civil aviation said hours before Monday's missile fire that King Khalid International Airport would remain closed, with several hundred flights cancelled, while safety and readiness checks were completed; Reuters reported the airport is scheduled to stay closed until October 17. Cirium data cited by Reuters showed 99.7 percent of scheduled flights at the airport cancelled on Sunday, skies over the capital largely empty on Monday, Lufthansa and Air France-KLM suspensions running to mid- and late October, a US Federal Aviation Administration caution to American airlines, and Delta Air Lines delaying its planned Atlanta–Riyadh nonstop launch to next spring. In a separate Reuters investigation published Monday, officials and analysts questioned why Saudi Arabia's public warning system — silent since September 29 — issued no alerts before the deadly airport strikes, with civil defence alerts only resuming on Monday.
What each side says
The Houthis say their airport and infrastructure strikes are a response to an escalated Saudi air campaign inside Yemen. On Monday the group claimed Saudi warplanes and missile units had carried out 119 attacks in the previous 24 hours, killing at least 14 civilians including women and children; CNN noted it could not independently verify that claim, and Signal Post News treats it as a Houthi claim, not an established figure. The group has also repeatedly warned airlines and travellers away from Saudi airports and said Saudi Arabia bears responsibility for the consequences of failed interceptions.
Saudi Arabia and its coalition partners say they are defending civilian airports, oil installations and population centres against ballistic missiles and drones, and describe the Houthis — who are aligned with Iran — as the party escalating a conflict that reignited in July after the Houthis made sudden advances, including around the Bab el-Mandeb Strait, the oil-shipping chokepoint Riyadh says it re-entered the war to protect. The United Arab Emirates on Monday called for revived joint Gulf action on security and defence, with presidential adviser Anwar Gargash saying the targeting of Saudi Arabia undermines the security of all Gulf states. Iran, for its part, offered on Monday to mediate between its Houthi allies and the kingdom, with foreign ministry spokesperson Esmaeil Baghaei saying Tehran has repeatedly expressed readiness to help facilitate dialogue.
On the ground in Yemen, the humanitarian ledger keeps growing underneath the missile exchanges: the International Organization for Migration reported on October 12 that more than 217,000 people have fled their homes since fighting escalated on Yemen's west coast, with the majority in Taiz governorate, many in sites aid workers cannot reach.
Why this matters
First, the threat changes the American calculation, which is its purpose. Until this week the question in Washington was whether helping Saudi Arabia was worth it; Bukhaiti's warning is designed to reframe it as whether staying out is even an option the Houthis will honour — by explicitly putting US interests across the region, which include bases, embassies, shipping and personnel in several Gulf states, in the target set if the US acts. That is a classic deterrence move, and it cuts both ways: it raises the cost of US entry, but it also gives Washington a stated reason to act before the threat is tested, and it makes any later Houthi attack on a US target far harder to walk back.
Second, the economics are already moving. Market reporting on Monday put Brent crude closing near $106 a barrel, up on the day and briefly above $107, as traders priced a conflict that now touches the world's largest oil exporter's airports, refineries and export infrastructure simultaneously. Saudi Arabia's exposure is not only physical: the Riyadh attacks struck during a major energy congress in the capital, senior executives of the biggest Western oil companies withdrew, and every cancelled flight and suspended route undercuts the kingdom's pitch that it is a safe, open hub for investment and tourism. The Houthis do not need to close the kingdom's oil exports to impose costs; keeping its main airport shut for a week does measurable damage on its own.
Third, the military problem is genuinely hard for both sides. Interceptions over Riyadh and Khamis Mushait on Monday show Saudi air defence working — three missiles destroyed, no reported casualties — yet the previous week's strikes got through often enough to kill at least 18 people, and a warning system that stayed silent left travellers in a terminal without alerts. For the Houthis, the inverse holds: they can still launch, but each missile expends a scarce arsenal against defences that are learning their patterns, and each civilian death at an airport strengthens the case their enemies are making in Washington.
What happens next
The immediate variable is Trump's decision. The options publicly discussed range from direct US strikes on Houthi launch sites and missile infrastructure, through a narrower package of air defence, intelligence and logistics support that stops short of American bombs, to holding off and pressing the mediation channels Iran mentioned on Monday and that Oman has historically hosted. Each carries a different reading of Bukhaiti's warning: joining the strikes tests it directly; a support-only role tests whether the Houthis treat enablers as participants; staying out leaves Saudi Arabia asking why its security partnerships did not answer a week in which its capital's airport was repeatedly hit.
The other variable is the airport itself. A reopening on the reported October 17 schedule, with airlines restoring services, would signal that Riyadh believes the interception problem is manageable; another successful strike, or another week of closures, would deepen both the economic damage and the pressure on Washington. And underneath the diplomacy, Yemen's displaced — 217,000 and rising, by the IOM's count — will judge this week not by statements in Riyadh, Sanaa or Washington, but by whether the bombing in either direction slows down at all.
