New front in US-Iran war escalates as Houthis fire at Saudi oil facilities

Conflict also spreads to Caspian Sea as Tehran accuses Ukraine of a deadly attack on an Iranian vessel.

Tehran-backed Houthi forces in Yemen have fired missiles and drones at two of Saudi Arabia’s most strategically important oil facilities on the Red Sea, in a major escalation of the latest simmering regional conflict to be reignited by the war launched by the United States and Israel against Iran.

But the skies over the country at the epicentre of the widening war were quiet for a second successive night, with no new US attacks on Iran reported by Sunday morning.

Iran had been pounded by 13 consecutive waves of overnight US air strikes since July 11, after the Islamic Revolutionary Guard Corps (IRGC) attacked tankers trying to transit the Strait of Hormuz. As hostilities escalated, both sides declared that an interim peace agreement signed in June was dead, and a second phase of talks to finalise a comprehensive peace deal appeared doomed.

But there have been no US air strikes since Friday, and tentative signs are emerging that Washington and Tehran are still talking via mediators and might return to more meaningful discussions.

Even if another fragile truce is agreed, however, the cascade of consequences unleashed by the war is still stoking conflict and confrontation elsewhere.

Iran’s attacks on shipping in the Strait of Hormuz have put a stranglehold on exports of oil and raw materials for fertiliser, sending energy prices soaring and raising the risk of a food security crisis in some of the world’s most vulnerable countries.

In March, in response to attacks on Iran, the Tehran-backed Hezbollah movement in Lebanon resumed missile attacks on Israel, which then launched a devastating invasion of southern Lebanon that has displaced 1.2 million people.

Risk of global crisis The truce collapsed this month after an attack on Sanaa airport to stop an Iranian plane landing provoked the Houthis to fire ballistic missiles at Saudi Arabia. Last Monday, the Houthis declared a naval blockade of Saudi Arabia, and late on Friday the Saudis launched air strikes on the Houthi-held city of Hodeidah.

In retaliation, Houthi forces launched Sunday’s attacks on facilities belonging to Saudi state oil giant Aramco in the coastal cities of Jizan and Yanbu, Houthi military spokesman Yahya Saree said.

There has been no comment from Saudi Arabia on the extent of any damage to Aramco’s refinery in Jizan, but a large column of smoke was seen rising after the attack.

In Yanbu, Saudi Arabia’s principal west coast export gateway, two ballistic missiles aimed at oil installations were intercepted by a Patriot battery operated in Saudi Arabia by the Greek military under an agreement ‌with Riyadh.

The escalating conflict has raised fears that the Houthis could block the Bab al-Mandeb Strait, which connects the Red Sea to the Gulf of Aden. If both the Bab al-Mandeb and Hormuz straits were blocked, the resulting supply chain crisis would cause major economic damage across the world.

Entangled wars

Besides spreading to the Red Sea, the US-Iran war has become entangled with the deadliest active conflict in the world – Russia’s attempted conquest of Ukraine.
