A Houthi missile strike on Riyadh’s King Khalid International Airport killed 13 people on Tuesday, prompting a senior Saudi minister to warn of a "serious response".

The attack, which also hit a nearby military logistics hub, disrupted dozens of flights and sparked immediate concern that the conflict in Yemen could spill further into the Kingdom.

According to the BBC, the missiles were launched from Houthi‑controlled territory in northern Yemen and struck the airport’s cargo terminal during peak arrival hours. DW News confirmed that the second target was a fuel storage facility used by the Saudi Air Force.

Witnesses described a loud explosion followed by a plume of black smoke that drifted over the runway. Emergency crews rushed to the scene, treating the injured and evacuating passengers from the terminal building.

"We will respond with seriousness," the minister of defence, Prince Khalid bin Salman, told reporters in Riyadh, adding that Saudi forces are prepared to take decisive action against any further aggression.

"We will respond with seriousness," the minister said.

The statement came as the United States, a long‑standing Saudi ally, weighed options ranging from diplomatic pressure on Tehran to direct military support for the Saudi coalition. A senior US defence official, speaking on condition of anonymity, said Washington is monitoring the situation closely and will coordinate any response with Riyadh.

Escalation risks a wider regional clash

Analysts at the International Institute for Strategic Studies warned that the strikes could trigger a new round of retaliatory air raids, potentially drawing Iran, which backs the Houthi movement, into a broader confrontation. The United Kingdom’s foreign office issued a travel advisory for Saudi Arabia, urging citizens to avoid non‑essential travel to the capital.

Saudi Arabia’s coalition, which has been fighting the Houthi rebels since 2015, has previously responded to missile attacks on oil facilities and shipping lanes with strikes on Houthi‑held ports. However, the targeting of a civilian airport marks a notable escalation in the rebels’ tactics.

Background to the conflict

The Yemeni civil war began when a Saudi‑backed coalition intervened to restore the internationally recognised government after the Houthis seized the capital, Sanaa, in 2014. Over the past decade, the coalition has carried out thousands of air strikes, while the Houthis have increasingly used ballistic missiles and drones to strike deep inside Saudi territory.

Iran’s alleged supply of missile technology to the Houthis has been a persistent point of friction between Tehran and Riyadh. The United Nations has repeatedly called for a ceasefire, but both sides accuse the other of violating previous agreements.

Implications for aviation and the economy

Airlines operating out of Riyadh reported a 40% reduction in scheduled departures in the 24 hours after the attack, according to a statement from the Saudi Arabian Airlines Association. The disruption is expected to affect the Kingdom’s tourism sector, which contributes roughly $30 billion to the economy each year.

Financial markets reacted modestly, with the Saudi stock index slipping 0.6% on Tuesday, reflecting investor unease over the possibility of a broader escalation that could hit oil production and export routes.

In the coming days, Saudi officials are likely to convene a high‑level security council to plan potential retaliatory strikes. The coalition’s next steps will be watched closely by regional powers, including the United Arab Emirates and Qatar, both of which have pledged support for Riyadh’s response.

The United Nations Security Council is scheduled to meet later this week to discuss the latest developments and to consider whether a new resolution is needed to curb the growing threat to civilian infrastructure in the region.
