Saudi Aramco's headquarters in Dhahran suffered extensive damage following a missile attack Tuesday night, with fires spreading across several floors of an office tower.

The attack struck the headquarters complex of the Saudi state-owned oil giant as fighting between the kingdom and Yemen's Iran-aligned Houthi rebels intensified.

The fire began on the ninth floor of the building's south wing before spreading between the sixth and 10th floors. The top three floors, which include the office of Aramco CEO Amin Nasser, were severely damaged. Parts of the ceiling collapsed, while windows and doors were blown out.

The fire continued burning into the early hours of Wednesday, according to a source familiar with the damage.

Despite the destruction, Aramco's operations have continued, according to two people familiar with the situation. Some employees have been instructed to work from home, while certain functions have been transferred to the company's international offices.

Saudi Arabia's Energy Ministry confirmed that an administrative building at the Dhahran complex was struck Tuesday night, causing what it described as a limited fire. Authorities reported no deaths or injuries.

The Dhahran headquarters is a key center for Aramco's global operations. The complex houses an operations center responsible for overseeing the company's extensive network of oil fields, refineries, pipelines and export terminals.

Although operations reportedly remain unaffected, the damage raises concerns about the security of Saudi Arabia's critical energy infrastructure as Houthi attacks against the kingdom continue.

The Houthis have stepped up missile and drone attacks on Saudi targets amid renewed fighting in Yemen. The group has threatened further strikes against Saudi airports and oil facilities, increasing the risk of additional disruption to the kingdom's energy sector.

The attack also comes amid wider instability in regional energy markets, with continued threats to commercial shipping in the Strait of Hormuz adding pressure to global oil supplies.

Aramco had not publicly responded to Reuters' request for comment as of Wednesday's reporting. The company has not released a detailed assessment of the damage or indicated whether repairs could affect longer-term operations.
