Yemen’s Houthi forces fired drones and missiles at the heart of Saudi Arabia’s oil industry on Sunday, including a Saudi Aramco facility at Ras Tanura vital to petroleum exports, in what Riyadh called a failed assault on global energy security, Reuters reported.

The Saudi energy ministry said there were no casualties or loss of property from the attacks.

The defence ministry said it intercepted an armed drone coming from the sea prior to hitting its target at an oil storage yard at Ras Tanura, site of a refinery and the world’s biggest offshore oil loading facility.

Reuters reported shrapnel from a ballistic missile fell near a residential compound in Dhahran used by state-controlled Saudi Aramco, the world’s biggest oil company, the ministries said.

The sites are located on the Gulf coast across from Iran and near Iraq and Bahrain.

Yemen lies thousands of kms southwest on the Gulf of Aden.

Announcing the attacks, the Houthis, who have been battling a Saudi-led coalition for six years, also said they attacked military targets in the Saudi cities of Dammam, Asir and Jazan, Reuters reported.

“Such acts of sabotage do not only target the Kingdom of Saudi Arabia, but also the security and stability of energy supplies to the world, and therefore, the global economy,” a ministry spokesman said in a statement on state media.

The Saudi-led coalition earlier said it intercepted 12 armed drones aimed at “civilian targets” without specifying a location as well as two ballistic missiles fired towards Jazan.

The Eastern Province is home to most of Aramco’s production and export facilities. In 2019, Saudi Arabia, the world’s top oil exporter, was shaken by a big missile and drone attack on oil installations just a few km from the facilities hit on Sunday, which Riyadh blamed on Iran, a charge Tehran denied.

That attack, which was claimed by the Houthis but which Riyadh said did not originate from Yemen, forced Saudi Arabia to temporarily shut more than half of its crude output, causing a huge price spike.

Reuters reported Houthi military spokesman Yahya Sarea said on Sunday that the group had fired 14 drones and eight ballistic missiles in a “wide operation in the heart of Saudi Arabia”.

The Houthis recently stepped up cross-border attacks on Saudi Arabia at a time when the United States and the United Nations are pushing for a ceasefire to revive stalled political negotiations to end the war.
