Houthi rebels carried out a drone attack on a Saudi Aramco oil refinery in the Jizan region of Saudi Arabia. Houthi military spokesperson Brigadier General Yahya Saree said in a statement that the refinery was struck “accurately and successfully” with a drone on Sunday. Al Masirah TV reported that a fire broke out at the oil refinery early Sunday.

Saree said Saudi Arabia had flown intelligence and surveillance drones over the airspace of Saada and Hajjah provinces in northern Yemen in recent days. He described those activities as “provocative” and said the refinery attack was carried out in response.

Saudi Arabia’s Energy Ministry said firefighters had extinguished the early-morning fire at one facility of the Aramco refinery. The ministry said there were no casualties in the incident.
