Houthis Claim Missile and Drone Strike on Aramco's Riyadh Refinery

The smoke came first. A witness told Reuters on Saturday that a large plume of smoke and fire was rising in the vicinity of an Aramco refinery in Riyadh. Hours later, Yemen's Houthi movement said it was responsible.

The group's military spokesman, Yahya Saree, said the Houthis carried out what he called a "qualitative military operation" against Aramco facilities in the Saudi capital, using ballistic missiles and drones. He framed it as retaliation: in the past 24 hours, he said, Saudi forces had carried out 60 airstrikes on Yemen, bringing the total since the escalation to 1,410.

What the satellite data shows

NASA's FIRMS monitoring system detected higher-intensity thermal readings across the Riyadh refinery, and satellite imagery showed smoke rising over the site. Houthi media posted footage and satellite images showing fires at oil storage tanks. What the data does not show is who started the fire. The cause could not be independently verified.

Neither Saudi authorities nor Aramco confirmed the fire. The Saudi-led coalition disputed the Houthi claim, calling assertions about a strike on Riyadh "misleading," according to market data provider Jin10. Separately, Iranian state media cited Arab sources as saying Yemeni forces also attacked the city of Dammam.

The other side of the exchange

Retaliation came quickly. Yemen's internationally recognized government said its forces were carrying out strikes against "vital targets" of the Houthis in Sanaa and Saada, the rebel-held capital and its northern stronghold. "The capabilities of the Houthi militia will not be safe from the fire of our armed forces," a government spokesman said.

The Institute for the Study of War reported at least 13 airstrikes on Sanaa City on October 3, aimed at weapons experts, missile and drone commanders, and other "high-value targets." The group said Yemeni government-aligned forces also struck Houthi positions, reinforcements, and logistics throughout southwestern Yemen on October 2.

A campaign, not a one-off

The strike claims are the latest turn in the Houthis' campaign against Saudi oil infrastructure. Last week the group said it attacked Aramco facilities in Yanbu, on the Red Sea coast. Saudi Arabia said it intercepted six ballistic missiles fired toward Taif and the Yanbu area and reported no damage to Aramco facilities.

In August the Houthis declared a naval attack against the kingdom and claimed strikes on the Yanbu and Jazan refineries, following a fire at the Jazan refinery in July. An independent geospatial analyst separately reported that the Houthis attacked oil refineries in Riyadh and Yanbu over the past 24 hours.

The Riyadh refinery is not one of Aramco's giants. Its capacity is about 130,000 barrels a day, according to Turkish outlet Türkiye Today. The point of an attack on it is the location: a strike at the capital's doorstep is meant to put political and economic pressure on Riyadh. The Houthis' demands, as tracked by the Institute for the Study of War, include an end to Saudi military activity and support for anti-Houthi forces in Yemen, lifted controls on Houthi-controlled ports and airports, war reparations and civil servant salaries, and Houthi control over Yemen's oil and gas resources.

For now, two sides are claiming two operations, and the fire in Riyadh remains officially unexplained. The region's oil market is watching what happens next.
