Iran-backed Houthi forces have claimed a total of six attacks on airports and oil facilities across Saudi Arabia, despite a rare high-level meeting between Saudi and Iranian officials in Tehran earlier this week.

The attacks came after Saudi Arabia, Turkey and Pakistan sent senior representatives to Tehran, where participants agreed to resolve regional differences through dialogue and to strengthen cooperation between the four countries.

Houthi spokesperson Yahya Saree announced the attacks in a statement posted on X, saying they targeted vital commercial and military infrastructure spanning Saudi Arabia from its east and west coasts to Riyadh and the southern region of Najran.

According to Saree's statement, the Houthis targeted the Ras Tanura oil refinery with a ballistic missile, an Aramco facility in Abqaiq with a missile, King Khalid International Airport in Riyadh with multiple missiles, King Fahd International Airport in Dammam with a drone, the Rabigh oil refinery with a ballistic missile, and a Saudi military headquarters in the Najran region.

There was no independent corroboration of the group's claims.

The escalation followed a meeting in Tehran on Monday hosted by Iran's security chief Mohsen Rezaei. Saudi Defence Minister Khalid bin Salman, Pakistan's army chief Asim Munir and Turkish intelligence chief Ibrahim Kalin attended the talks, which focused on peace and security in the region.

Following the meeting, the Saudi foreign ministry stressed "the importance of opening channels of negotiation to prevent a return to military escalation."

The Saudi-led coalition said its air defences intercepted and destroyed two ballistic missiles fired by the Houthis toward the capital, according to coalition spokesman Turki al-Maliki.

Saudi Arabia's Civil Defence said shrapnel from the interception wounded one Saudi citizen in Riyadh. Shrapnel also damaged a house and a vehicle, according to the agency's spokesperson.

Warning alerts for incoming threats had been issued in Riyadh, the al-Kharj governorate and Najran city ahead of the announced interceptions.

Earlier on Thursday, the internationally recognised Yemeni government issued a statement calling on the UN Security Council to take "deterrent and punitive measures" to stop Houthi attacks on Aden International Airport.
