Yemen’s Iran-aligned Houthi movement said Saturday, September 19, 2026, that it attacked “sensitive” sites in the Saudi capital Riyadh with missiles and drones — hours after flames and a large plume of black smoke were seen near King Khalid International Airport, Reuters and the BBC reported.

Saudi Arabia’s government media office did not immediately confirm the Houthi’s claim or identify the cause of the fire. Reuters said there was no immediate Saudi confirmation of the attack claim when the agency asked.

What was seen in Riyadh

Reuters video and photographs showed a huge pillar of black smoke rising near the airport, with the highway, main terminal, and other facilities in the foreground. At one point flames were visible rising from behind what appeared to be fuel tanks. A Reuters caption described the plume as rising from the fuel storage depot at King Khalid International Airport.

An AFP journalist reported firefighters working to extinguish a burnt-out fuel tank bearing Aramco branding near the airport, per BBC and Straits Times accounts of that reporting. FlightRadar24 listed major problems at the airport, with delays and cancellations, the BBC and Straits Times said.

Saudi Civil Defence sent overnight phone alerts warning of potential aerial danger in Riyadh and Al-Kharj east of the capital, then issued an all-clear Saturday morning, Reuters reported. A Reuters journalist in Riyadh’s Olaya area heard booms before the all-clear. Residents told AFP they heard explosions after the alerts; one northern Riyadh resident said, “I heard the alarm, then my windows shook,” according to the BBC.

Reuters said these were the first such capital alerts since the Houthi escalation with Saudi Arabia began in July, though some alerts had been issued earlier in the year after the start of the US–Iran war.

What the Houthis claimed

Houthi military spokesman Yahya Saree said a “large number of ballistic and cruise missiles and drones” hit “sensitive sites” in Riyadh and Aramco facilities in the Red Sea export hub of Yanbu, the BBC reported, casting the operation as retaliation for alleged Saudi strikes on Sanaa.

The Houthis did not specify which Riyadh sites they hit, Reuters noted. Riyadh has not publicly confirmed either the capital strike claim or the Yanbu claim in the reporting cited here.

Wider context

The Houthis have been striking Saudi cities, energy infrastructure, and shipping since declaring a naval blockade against Riyadh in July, Reuters reported — adding pressure on Gulf oil export routes while the Strait of Hormuz remains disrupted by the wider Iran war. The UN Security Council on Friday condemned continued Houthi attacks on Saudi Arabia, including strikes that injured civilians, Reuters said.

What Saturday’s smoke proves on its own is a fire at or near the airport’s fuel storage area, civil-defence alerts, and a Houthi claim. What it does not yet prove — without a Saudi confirmation or independent battle-damage assessment — is that every Houthi missile and drone hit its stated target. The pictures and the claim are both real; the government’s silence is the open fact in between.
