Yemen’s Houthi militia announced that it launched a wave of ballistic missiles and unmanned aerial vehicles at Saudi Arabia’s capital, Riyadh, and at key oil installations in the western port city of Yanbu, prompting Saudi air‑defence systems to engage the threats and causing disruptions at the city’s international airport.

Attack claims and Saudi response

The Houthis, which are aligned with Iran, claimed on Saturday that they targeted “sensitive sites” in Riyadh and the Yanbu oil complex with missiles and drones. The group released footage showing a large plume of black smoke rising near the airport, which it presented as evidence of a successful strike on a fuel depot.

Saudi authorities, speaking through the Saudi-led coalition’s military communications centre, said that a ballistic missile was detected en route to Riyadh and was intercepted by the kingdom’s air‑defence network. No damage to critical infrastructure or casualties were reported.

“Our air‑defence systems have successfully intercepted the ballistic missile aimed at the capital,” the coalition’s spokesperson said, according to PBS.

The missile interception was described as the first time an air‑raid alarm has been sounded in Riyadh since the escalation of hostilities between the Houthis and Saudi‑backed forces earlier this year, according to Al Jazeera.

Impact on Riyadh airport and oil infrastructure

Eyewitness accounts and video footage captured thick black smoke and flames near Riyadh’s King Khalid International Airport shortly after the alerts were issued. The smoke plume was visible from the airport’s perimeter, prompting the closure of several runways and the cancellation or delay of numerous flights, as reported by France 24 and the BBC.

Saudi officials confirmed that the fire originated at a fuel depot adjacent to the airport, but they added that the blaze was quickly contained by emergency crews. The incident caused a temporary disruption to airport operations, though no passenger injuries were reported.

In addition to the capital, the Houthis said they struck the Yanbu port, a strategic hub for the kingdom’s oil exports. Saudi state media and the coalition’s statements, however, said that “all attacks were thwarted” and that the oil facilities continued to operate without interruption.

Regional implications

The attacks come amid a broader intensification of the conflict that began after the Houthis launched a series of drone and missile operations against Saudi oil infrastructure in 2019. The latest wave of strikes underscores the growing reach of the Houthi campaign, which Tehran is widely believed to support, and raises concerns about the security of Saudi energy assets.

Western analysts note that the ability of the Houthis to target the Saudi capital represents a significant escalation. The New York Times described the operation as “a notable shift in the theatre of the war,” while The Guardian highlighted the presence of “thick smoke” as a visual reminder of the conflict’s expanding geography.

U.S. officials have previously warned that Iranian involvement could broaden the conflict’s scope, and the latest incident may prompt renewed diplomatic efforts to de‑escalate tensions. Iran’s foreign ministry, as cited by Iran International, expressed a desire for an end to the Saudi‑Yemeni hostilities, calling the recent attacks “dangerous escalations.”

Overall, while Saudi Arabia reports that its defences successfully neutralised the missile threat and that vital oil facilities remain operational, the incident has heightened regional security concerns and highlighted the vulnerability of high‑profile targets in the kingdom.
