A missile attack on King Khalid International Airport in Riyadh on Saturday 10 October killed at least 12 people and wounded dozens, The Wall Street Journal and The New York Times reported. Three people briefed on the matter told Reuters the toll may rise. Saudi officials told the WSJ that missiles hit Terminals 3 and 4 directly, that several of the injured were in critical condition and that parts of the roof fell on people inside. The NYT called it the deadliest attack in a Gulf Arab country since the US-Israeli war with Iran began in February, and Reuters described it as the deadliest attack in the kingdom since a 2015 mosque bombing in Qatif. A regional official told the Associated Press (AP) that "many people were wounded." Terminal 3 is part of a complex housing Terminals 3 and 4, used for domestic flights. Saudi authorities ordered a full evacuation, suspended all operations and diverted incoming flights. FlightAware reported at least 291 Riyadh flights cancelled over the preceding 24 hours.
Reporting attributes the strike to the Houthis, the Iran-backed movement that controls much of northern Yemen. The group has not claimed it. It did claim the previous attack on the airport on Thursday 8 October. That day three Saudi nationals were killed, including Saudia pilot Captain Hamoud Ali Alkalthami. Attacks on Abha and Riyadh airports earlier in the week killed three more people. Including Saturday's attack, at least 18 people have been killed in attacks on Saudi airports this week. A Saudi information blackout limits independent verification.
An interceptor stockpile under strain
On the reporting so far, the strongest answer is not range but depth of defence. Regional officials told AP last month that Saudi Arabia was running low on missile interceptors and had asked France, Britain, Pakistan and Egypt for air defence support. One official said US interceptor stocks have also dwindled during the Iran war.
Distance does not explain it. Riyadh lies more than 800 kilometres (500 miles) from the Yemen-Saudi border, yet the Houthis have claimed strikes there since at least September. On 19 September Crisis.Zone reported an Aramco fuel depot fire near the same airport. Multiple outlets said that day's alerts were the first sent to the capital since the escalation began in July. The Houthis claimed strikes on unspecified "sensitive sites" in Riyadh. Saudi authorities did not state a cause for the fire. The pattern also extends beyond the capital. Yemen's Transport Ministry said two ballistic missiles and several drones were fired at Aden airport on 7 October.
A Saudi-backed Yemeni government offensive, Operation Dawn of Yemen, is under way. Coalition spokesman Maj. Gen. Turki al-Malki said this week that the coalition had destroyed 136 Houthi military targets. He said they intend to destroy the group's ballistic missile capabilities. That is a stated intent, not an outcome.
Observers are reading: how the UAE rift, the US misreading and the interceptor shortage combine to limit Riyadh's options over the coming weeks.

What the answer does not settle
On current reporting, Riyadh's airport appears reachable in large part because of an interceptor shortage. Strategic choices made before the offensive and ad hoc outside support add to it. Three limits apply. The Houthis have not claimed Saturday's strike. Casualty figures are preliminary. The Saudi information blackout warns the public that filming or sharing information on missile interceptions and impact sites "exposes you to legal liability", and it restricts independent checks.
The commercial effects are already visible. Kuwait Airways, Air India, flydubai, Lufthansa Group and Pakistan International Airlines have suspended flights to Saudi airports. The European Union Aviation Safety Agency has warned that missile and drone attacks and interception efforts "create an increased risk of misidentification of civil aircraft." The Saudi and Omani foreign ministers spoke by phone about "supporting diplomatic solutions to de-escalate tensions." Whether defences or diplomacy shift first remains unresolved.
