The conflict between Saudi Arabia and Yemen’s Houthi movement escalated sharply on Tuesday, October 13. The Saudi-led coalition struck Houthi-held energy sites in Yemen, and the Houthis responded by declaring Saudi oil installations legitimate targets. The exchange follows a missile strike on King Khalid International Airport in Riyadh on Saturday, October 10.
Saudi Arabia’s General Authority of Civil Aviation said the missile killed 12 people and wounded 309, according to Al Jazeera. Al Jazeera described it as the deadliest attack in the kingdom in more than a decade. Other reports, including France 24, put the toll at 13 dead and more than 300 injured, so the figure remains slightly inconsistent across outlets.

What happened
The Houthis fired again on Sunday, and Al Jazeera reported that the strike killed one person and wounded 11. Al Jazeera also reported a third consecutive day of attacks on Monday. Saudi forces said they shot down a ballistic missile over Riyadh, while Houthi military spokesman Yahya Saree said the group had targeted the airport and sent a drone toward the Khamis Mushait air base near the Yemeni border.
Saree has also warned airlines and travellers against using Saudi airports, with the exception of Mecca and Medina, according to Al Jazeera. CBS News reported that Riyadh’s airport is suspended through October 17. Jeddah and Dammam remain open with delays and cancellations, according to the US State Department. The department now requires US government employees in the kingdom to obtain special authorisation before using any Saudi airport. CBS also reported that Delta Air Lines has delayed plans for nonstop Atlanta to Riyadh flights.
On Tuesday the coalition said it had hit energy facilities in Houthi-held areas. According to The National, these included the Al Sabahah station in Sanaa and fuel-loading piers at Hodeidah port. Coalition spokesman Turki Al Malki said the Houthis were using civilian infrastructure to support military operations. He said the aim was to neutralise their ability to threaten Saudi Arabia, Yemen, the Red Sea and international shipping lanes.

The Houthi side offered a different account. The Houthi-run health ministry said two people died in a separate attack on an oil company in Hodeidah province and blamed Saudi Arabia, France 24 reported. Saudi Arabia did not immediately confirm that strike. Al-Monitor reported that Saree urged civilians to evacuate Saudi Aramco’s headquarters in Dhahran, the company’s Riyadh refinery and King Khalid airport. CBS News said witnesses heard blasts near an Aramco facility in Dhahran, and the coalition said it destroyed two Houthi ballistic missiles fired at the kingdom’s east.
Background
The Houthis control Yemen’s most populous areas, including Sanaa. Saudi Arabia and the Houthis fought a long war after a Saudi-led coalition intervened in 2015. The current fighting sits inside a wider regional crisis tied to the US-Iran war. Geopolitical Futures noted in mid-September that the Houthis had stayed out of Iran’s war with the United States while using the broader Gulf conflict to advance their own aims. The latest attacks suggest that restraint toward Saudi Arabia has ended.
Al-Monitor reported that President Donald Trump said the Houthis are acting at Iran’s behest. CBS News reported that Trump is weighing whether to join Saudi Arabia in attacking the group, and that the Houthis have threatened a “painful” response if the US does so. Iran’s role is asserted by Washington. The Houthis have historically denied being a Tehran proxy, a position noted in earlier Reuters reporting on the conflict, and nothing in current coverage resolves that dispute.
Why the air defence question matters
Al Jazeera ran an analysis asking why Houthi missiles are getting through Saudi air defences. It was prompted by Saturday’s strike, which hit a heavily populated capital rather than a border area. The US and UK issued new travel warnings for their citizens after the strike, and the French embassy in Riyadh told citizens to avoid Saudi airports targeted by the Houthis, according to France 24. The Houthis have said Saudi Arabia bears responsibility for any failed interceptions, which turns air defence performance into a political and reputational test for Riyadh.

Strategic and market implications
The main shift is the reciprocal targeting of oil assets. Saudi Arabia is among the world’s largest crude exporters, and Aramco’s eastern facilities in Dhahran are central to that role. The Houthis’ stated shift to Saudi oil installations raises the risk of physical disruption beyond a regional security problem. Hodeidah, the Red Sea port where the coalition hit fuel-loading piers, also handles a large share of Yemen’s commercial and humanitarian imports, so strikes there carry humanitarian consequences.
Markets are already pricing in geopolitical risk. FXStreet reported on Tuesday that gold was struggling below $4,200 while geopolitical tension in the Middle East and over Russia and Ukraine kept inflation expectations elevated. The same report said oil prices and US Treasury yields had retreated from recent multi-month highs. That suggests the market has not yet priced in a sustained hit to Gulf supply. A confirmed strike on Saudi energy infrastructure could change that quickly.
For Washington, the choice is between joining the Saudi campaign and risking a direct Houthi response, or staying out and leaving a key Gulf partner exposed. For Gulf states and airlines, the immediate concern is aviation safety and the continued operation of regional hubs.
What to watch
- October 17: the date through which Riyadh’s King Khalid airport is suspended, and whether authorities extend the closure.
- Aramco sites: any confirmed hit on Dhahran or the Riyadh refinery, and any official Saudi statement on output or exports.
- US decision: whether Trump commits US forces to strikes on the Houthis, and how the group responds.
- Red Sea shipping: whether the Houthis extend their threats to commercial vessels, and any change in insurer or carrier behaviour.
- Hodeidah: independent confirmation of casualties and damage at the port, and humanitarian agency statements on import flows.
- Diplomacy: any mediation by Oman or other regional actors, and whether the US-Iran track affects Houthi conduct.
