A correspondent for AFP news agency reported that queues formed at petrol stations in Sanaa on Tuesday afternoon following the coalition’s warning of an impending operation against the al-Sabaha oil facility, with many residents worried about shortages.

The Yemen Petroleum Company, which is run by the Houthis, issued a statement that sought to reassure them, saying the facility “does not contain any stock of petroleum products”.

The company also said it had “taken all necessary precautionary measures to address any emergency, ensuring the stability of the supply situation and the continued meeting of citizens’ needs in a normal manner”.

After al-Maliki confirmed the strike, first reported by Houthi media, explosions were heard over Riyadh and other Saudi cities, with al-Maliki reporting four missiles and two drones had been intercepted near the capital.

Yemen has been devastated by a civil war that began in 2014, when the Houthis ousted the internationally-recognised government from Sanaa. The conflict escalated in 2015, after the Saudi-led coalition of Arab states intervened in an attempt to restore the government’s rule.

A four-year-old informal ceasefire began to unravel in July, when the Houthis announced a “maritime embargo” against Saudi Arabia and began missile and drone attacks on Saudi airports, oil facilities and tankers in the Red Sea.

The Houthis said they were retaliating for what they call a Saudi blockade of their territory, as well as an air strike on Sanaa airport that they blamed on the kingdom.

The conflict escalated in September after the Houthis seized part of Yemen’s south-western Red Sea coast near the Bab al-Mandab Strait, a chokepoint for global shipping. Their advance contributed to a rise in oil prices following six months of war between the US, Israel and Iran.

US President Donald Trump said on Truth Social on Tuesday the Houthis were “behaving very badly… and purposefully trying to drive up Oil Prices”.

Speaking to reporters, he did not answer a question on whether he’d made a decision to help the Saudis retaliate against them, but said he “might” ask Turkish President Tayyip Erdogan to intervene.

Last week, pro-government forces said they had regained control of territory overlooking Bab al-Mandab after launching a major counter-offensive with the support of Saudi air strikes.

Hundreds of people have reportedly been killed in Yemen since August. The UN’s human rights office says they include at least 54 civilians, half of them children.

More than 216,000 people have also been displaced across the country, and suspected cholera cases have tripled in three weeks, rising from 217 to 647, according to the UN.
