Yemen's Iran-backed Houthi rebels struck Saudi Aramco's headquarters complex in Dhahran on Tuesday night, damaging an office tower and sparking a fire that spread across several floors.

Saudi Arabia's Energy Ministry described the incident as causing a limited fire with no injuries or fatalities reported. However, three people with direct knowledge of the matter told Reuters that the attack caused extensive damage, including to the top three floors where Aramco CEO Amin Nasser's office is located, with part of the ceiling caved in and windows and doors blown out.

The facility hosts a major operations center overseeing the company's vast network of oil rigs, refineries, pipelines, and export terminals. Operations continued normally, though some employees were directed to work from home and certain functions shifted to global offices.

The Houthis claimed responsibility on Wednesday, stating they targeted Aramco facilities in Dhahran along with Riyadh's airport and an Aramco refinery in the capital using ballistic missiles, cruise missiles, and drones. They vowed further attacks on Saudi airports and oil infrastructure, framing the strikes as retaliation for Saudi-led coalition actions in Yemen.

This latest escalation follows a deadly Houthi attack on Riyadh's King Khalid International Airport last Saturday that killed 13 people. Saudi forces have intercepted multiple missiles and drones in recent days, with debris from interceptions injuring four civilians in Riyadh and causing limited damage to homes.

The conflict has intensified amid broader regional tensions tied to U.S.-Iran confrontations in the Gulf. Saudi Arabia has conducted strikes on Houthi-controlled sites in Yemen, including fuel depots and energy facilities used to support missile and drone operations.

Aramco, the world's largest oil company, has maintained energy supply resilience despite the threats. The attacks underscore the persistent risks posed by the Iran-supported Houthis to critical infrastructure in the region.
