The Houthis have been launching missiles and drones at airports, oil and gas facilities, and military bases in Saudi Arabia in retaliation for the strikes on the territory that they control in western Yemen, including the capital Sanaa.
On Saturday, a Houthi missile strike killed 13 people at Riyadh’s international airport, which was the deadliest attack in Saudi Arabia in more than a decade.
Saudi Arabia’s deputy foreign minister accused Iran of encouraging the Houthis to escalate their conflict with the kingdom.
“Iran continues to arm, train and support the Houthi militia in violation of UN Security Council resolutions,” Rayed Krimly told reporters, according to AFP news agency.
“We think that the escalation by the Houthis at this latest stage of the conflict is encouraged by Iran,” he added.
There was no immediate response from Iran’s government. However, it has previously denied supplying weapons to the Houthis and said it only supports them politically.
Iran’s foreign minister has also said it is ready to provide “any assistance necessary to facilitate the start of talks” between Saudi Arabia and the Houthis.
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.
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.
At least 1,282 people have been killed and 5,890 injured in the fighting in Yemen since 6 August, according to the government’s health ministry.
The UN says another 201,000 people have been displaced and that there has been an alarming surge in suspected cholera cases.
