The Houthis struck the headquarters of national Saudi oil giant Aramco in Dhahran, Saudi Arabia, overnight, marking the latest airstrike barrage from the Iran-backed Yemeni rebel group against the kingdom.

According to the Saudi Ministry of Energy, there were no casualties after the airstrike sparked a “limited fire” in the administrative building near the country’s Eastern coastline. The fire from the airstrike, however, reportedly engulfed three floors of the building, causing significant damage to the company’s offices, including the CEO’s office, according to various outlets, including the Associated Press.
