Saudi Arabia hasn't confirmed any of it. No comment on the smoke, no comment on the alerts.
One more thing. FlightRadar24 has King Khalid International Airport at its worst disruption level right now. Cancellations. Long delays.
That's everything we know.
Why this mattersSo here's why this matters.
If the Houthis really did hit that fuel depot, this is huge. It's the first time in four years they've reached Riyadh's actual international airport.
Until now this war stayed down south, on Saudi Arabia's border, and out in the Red Sea. Not anymore.
And this has been building for months. Back in July, the Houthis declared a naval blockade on Riyadh. They started hitting Saudi oil tankers and facilities in the Red Sea. Then this month, they took the entire Red Sea coast of Yemen. The Bab al-Mandab Strait included. Officials called it a lightning advance.
And that strait matters more than ever right now. Because Iran has been closing the Strait of Hormuz in its own war with America and Israel. So Bab al-Mandab is one of the few doors left open.
Three days ago, Houthi military spokesperson Yahya Saree said his group hit an airbase in Khamis Mushait and Aramco sites in Yanbu. Saudi Arabia didn't confirm that one either. Saudi Arabia said 13 people were wounded in those attacks. It issued alerts for Mecca, Jeddah and Taif, then cancelled them. And it says it hit back with more than 50 strikes on Houthi-held areas.
Saudi Arabia has been trying to get help from outside too. Mohammed bin Salman, the Saudi Crown Prince, met Egypt's President, Abdel Fattah al-Sisi, to talk military cooperation. That came after Donald Trump turned down a personal request from Mohammed bin Salman for America to step in directly. Donald Trump says the Houthis themselves called Washington and asked it to stay out.
And just the day before this strike, the United Nations Security Council put out a statement condemning what it called continued Houthi attacks on Saudi Arabia that have wounded civilians, including women and children.
But here's the thing. Not everyone agrees on what actually burned this morning. One Saudi journalist says the fire started at a house, not the airport. Claims that two Aramco tanks and the cargo area got hit, and that two runways went out of use, haven't been confirmed by anyone. The Houthis also say they hit Najran Airport down south. Riyadh hasn't confirmed that one either.
Oil markets are already reacting. Brent crude closed the day before at around $104 a barrel, with the Hormuz closure and the Red Sea attacks already priced in.
So three questions are sitting wide open. What actually caught fire. Whether it really was the airport's fuel depot. And how Saudi Arabia responds.
Saudi Arabia has hit back hard before. Nobody knows yet if this is the moment for another round, or something much bigger.
