US National security adviser Jake Sullivan said on Sunday that the United States condemns the attacks by the Iran-backed Houthi militias in Yemen on civilian infrastructure in Saudi Arabia.
He called on the Houthis to cooperate with the UN and de-escalate the conflict in Yemen.
The Houthis fired missiles and drones at Saudi energy and water desalination facilities, causing a temporary drop in output at a refinery but no casualties, the Saudi Energy Ministry and state media said on Sunday.
Later on Sunday, another Aramco distribution plant was attacked in the Red Sea city of Jeddah, leading to a fire in one of the tanks, according to the Saudi-led Arab coalition. The fire was controlled and did not result in any casualties, it said.
