Yemen Houthis attack Saudi energy facilities, refinery output hit

RIYADH (Reuters) - Yemen's Iran-aligned Houthi group 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.

Drone strikes hit a petroleum products distribution terminal in the southern Jizan region, a natural gas plant and the Yasref refinery in the Red Sea port of Yanbu, the ministry said in a statement.

"The assault on Yasref facilities has led to a temporary reduction in the refinery's production, which will be compensated for from the inventory," it said, referring to Yanbu Aramco Sinopec Refining Company, a joint venture between Saudi Aramco and China Petrochemical Corporation (Sinopec).

The Saudi-led military coalition that has been battling the Houthis in Yemen for seven years said the assaults on Saturday night and Sunday morning had also targeted a water desalination plant in Al-Shaqeeq, a power station in Dhahran al Janub and a gas facility in Khamis Mushait.

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 coalition. The fire was controlled and did not result in any casualties, it said.

Houthi military spokesperson Yahya Sarea said the group had fired ballistic and winged missiles as well as drones at Aramco facilities in the capital Riyadh, Yanbu and "other areas," followed by attacks on "vital targets" in other Saudi regions.

POSSIBLE TRUCE

It said the attacks and debris from intercepted projectiles caused material damage but no loss of life.

The coalition said initial investigations showed the group used Iranian-made cruise missiles on the desalination plant and Aramco's Jizan distribution centre. It said Saudi air defences intercepted a ballistic missile and nine drones.

State media posted images and videos of projectile debris, damaged cars and structures, and firefighters dousing flames.

U.S. National security adviser Jake Sullivan said that the United States condemned the attacks.

Saudi Arabia has struggled to extricate itself from the war in Yemen which has killed tens of thousands and left millions of people there facing starvation. Houthi attacks on Saudi Arabia have also endangered the kingdom's airports, oil facilities and caused some civilian deaths.

United Nations special envoy Hans Grundberg is discussing a possible truce during the Muslim holy month of Ramadan which starts in April, his office said on Sunday. It was unclear if both sides had agreed on the U.N. plans.

The Houthis ousted Yemen's government from the capital, Sanaa, in late 2014, prompting the alliance to intervene. The conflict is seen as a proxy war between Saudi Arabia and Iran. The Houthis say they are fighting a corrupt system and foreign aggression.
