Why this mattersSo is this new? Not really.
Three weeks ago the Houthis said the exact same thing. Same drone type, a Wing Loong II, shot down near Mocha. Saudi Arabia never confirmed that one either.
But here's why it matters now. This is landing in the middle of the worst week this war has had in years.
Since 6 October, Houthi missiles and drones have been hitting Saudi airports. Riyadh's King Khalid International, Abha, Dammam's King Fahd. More than 20 people are dead. Over 370 are wounded.
The worst strike hit King Khalid airport three days ago. 12 to 13 people killed. Around 300 wounded. The deadliest attack on Saudi Arabia in over ten years.
A day after that, another strike on the same airport killed a Pakistani resident and wounded 11. The day after that, the coalition says it shot down three missiles heading for Riyadh and Khamis Mushait.
King Khalid airport is still shut. It's set to stay closed until at least 17 October.
And Saudi Arabia is now looking into why its own air defences let that first barrage through.
The ground war is widening too. The Saudi-backed Yemeni government launched an offensive called Dawn of Yemen just over a week ago, to take back Houthi territory. A ceasefire that had mostly held since 2022 is gone.
Prince Abdulaziz bin Salman Al Saud, Saudi Arabia's Energy Minister, says the kingdom's response now has to be equally serious.
And there's America too. Donald Trump says the US may join Saudi operations against the Houthis. He said they were behaving very badly.
Mohammed al-Bukhaiti, from the Houthis' political bureau, has a warning back: a swift and painful response against American interests if Washington joins in.
Hans Grundberg, the UN's envoy for Yemen, calls the airport strikes a grave escalation.
So here's the real question. If the Houthis can actually bring down Saudi drones over their own skies, that's not just missiles getting through anymore. That's air superiority in question too.
Saudi Arabia hasn't confirmed any of it. Right now, nobody outside the Houthi movement can say whether that drone ever came down.
