On Saturday, a Houthi missile struck King Khalid International Airport in Riyadh, killing at least twelve people and wounding more than three hundred. The dead included four Saudi citizens and nationals from Bangladesh, the United States, Egypt, Jordan, Syria, Palestine, and Sudan. The blast collapsed part of a terminal ceiling while passengers waited to board, and operations at the airport were suspended. Subsequent strikes followed, one of them killing a Pakistani resident and wounding others. Saudi authorities described the Saturday attack as the deadliest on the kingdom in more than a decade. Houthi spokesmen claimed responsibility for multiple launches against the capital’s airport and other sites, warning airlines to avoid Saudi airspace.
The episode fits a broader pattern that has developed since the United States and Israel began their campaign against Iran earlier in the year. In February, Iranian forces struck all six members of the Gulf Cooperation Council, hitting energy facilities, airports, desalination plants, and military sites. Those attacks disrupted commercial life for weeks, closed airspace, and forced schools and businesses to shut. Qatar had already absorbed an Iranian missile barrage on an airbase hosting American troops and, separately, an Israeli strike in Doha that killed Palestinian and Qatari nationals. The cumulative effect has been to erode the long-standing expectation that Gulf capitals would remain largely insulated from the region’s larger wars.
Investments in tourism, sports, and entertainment have proved especially vulnerable. Gulf governments spent heavily to host Formula One races, golf tournaments, and boxing events that project an image of stability and openness. Cheap drones and missiles can interrupt those calendars with little warning, raising insurance costs and deterring visitors. The economic damage extends beyond spectacle. Temporary closures of airports and shipping routes raise the price of imported goods and complicate the movement of skilled workers on whom the region’s service economies depend.
In Yemen, the 2022 de facto division of territory between Houthi-controlled areas and the internationally recognized government had held, with only intermittent fighting. The broader Iran war altered the incentives. Closure of the Strait of Hormuz redirected commercial traffic toward the Red Sea, increasing the value of coastal positions near Bab al-Mandab. Houthi forces advanced along Yemen’s western coast in September, seizing the port of Mokha and positions that brought them closer to the strait. Saudi-backed government troops later launched a counteroffensive and claimed to have regained stretches of the coast, though control remains contested and Houthi media disputed the extent of the losses. Fighting has also intensified around Taiz, where government forces face pressure on multiple sides.
The Houthis are not simply an extension of Iranian command. They maintain their own political goals inside Yemen and a long-standing hostility toward Saudi Arabia that predates the current regional war. Houthi officials have framed recent strikes on Riyadh as retaliation for Saudi air operations that they say have hit civilian infrastructure inside Yemen. That framing resonates with a constituency that views the House of Saud as an overbearing neighbor rather than a partner. Iranian support in the form of weapons and technical advice remains important, yet local recruitment, taxation, and ideological mobilization give the movement staying power that external patronage alone cannot explain.
Saudi Arabia has sought American military assistance against the Houthis and received limited support. United States officials provided intelligence and targeting data, and more than two hundred American personnel have been present in the kingdom for non-kinetic roles. Direct airstrikes were declined. After meetings with Houthi representatives in Oman, Washington concluded that the group would continue to spare United States shipping while treating Saudi-linked vessels as legitimate targets. The distinction reflects competing priorities: the United States remains focused on the Iran front and prefers not to open a second major campaign in Yemen. Saudi leaders, who recently concluded large investment commitments and a defense agreement with Washington, have found that those arrangements do not automatically translate into kinetic support when the Houthis threaten Red Sea routes used by Saudi exports.
The practical consequences for energy markets are still unfolding. Even partial disruption of Bab al-Mandab forces tankers onto longer routes around Africa, raising freight costs and delivery times. Saudi Arabia can shift some crude exports through its East-West pipeline to the Red Sea, but that infrastructure itself has been targeted. Houthi capacity to launch missiles and drones from positions well inland means that physical control of the strait’s shoreline is not the only requirement for interference. Insurance premiums for vessels transiting the area have already risen, and some carriers have voluntarily diverted traffic.
Past Saudi-led campaigns against the Houthis between 2015 and 2022 demonstrated both the difficulty of decisive victory and the high civilian cost inside Yemen. Those operations contributed to a humanitarian crisis that killed hundreds of thousands through direct violence and the collapse of basic services. A renewed ground effort, even with air cover, would face the same logistical and political constraints. Houthi forces have shown a capacity to absorb losses and continue operations from mountainous terrain, while Saudi Arabia’s public tolerance for prolonged casualties and economic disruption is limited. Neighboring states such as Pakistan have signaled a willingness to honor mutual defense understandings, yet the scale of any external contribution remains unclear.
The wider regional picture compounds the pressure. The Iran war has not ended, Gaza continues to generate political and humanitarian fallout, and Israeli operations in Lebanon have not produced a stable ceasefire. Each of these theaters creates incentives for actors to open or escalate secondary fronts. For Gulf governments, the calculation is no longer whether the old security architecture can be restored, but how to manage risks under a more fragmented set of guarantees. Diversifying arms suppliers, expanding indigenous defense industries, and pursuing limited diplomatic channels with adversaries are all under discussion. None of those steps, however, removes the immediate vulnerability demonstrated by repeated strikes on civilian airports and energy facilities.
The Riyadh attacks have made that vulnerability concrete for a public unaccustomed to large-scale casualties on its own soil. How Saudi Arabia and its partners choose to respond will shape whether the current flare-up remains a contained exchange or expands into a longer confrontation along the Red Sea coast. In either case, the assumption that Gulf stability can be secured primarily through traditional alliances has already been tested and found incomplete.
