Yemen’s Houthis on Oct. 11 claimed responsibility for the previous day’s ballistic missile strike on a passenger terminal at Riyadh’s King Khalid International Airport, the deadliest attack on Saudi Arabia in a decade. In a televised speech, Houthi military spokesman Brig. Gen. Yahya Saree also claimed attacks on King Fahd International Airport in Dammam and on two Saudi Aramco facilities, Reuters reported. The death toll from the Oct. 10 strike rose to 13 when an Indian national died of his injuries, the Indian Embassy said. Saudi authorities have put the number of wounded at 309.

According to the Saudi-led coalition, the airport was struck again on Sunday, causing a fire, while another missile was intercepted, The National reported. Later in the day, Saudi Arabia’s King Fahd International Airport in Dammam was also attacked. The Houthis claimed they also struck Aramco’s Shugadam gas facility and Tanajib oil refinery in the Eastern Province.

Houthi spokesman Yahya Saree said in a post on X the attacks respond to “treacherous Saudi aggression,” claiming Saudi Arabia had launched more than 120 airstrikes on Houthi-held territory in 24 hours. The Houthis also said the airport in Sanaa had been struck again, blaming the Saudis. Saree warned all potential travelers that Saudi Arabia’s airports “are not safe,” vowing to enforce “siege with siege, escalation with escalation.”

Saudi-led coalition spokesman Maj. Gen. Turki al-Malki called Saturday’s strike a “cowardly terrorist attack” and “a full-fledged war crime,” Al Arabiya reported. He said the coalition’s Joint Forces Command “will respond decisively.”

Also on Oct. 11, Saudi Arabia, Egypt, Pakistan and Türkiye issued a joint statement condemning the attacks “in the strongest terms” and calling them a blatant assault on Saudi sovereignty. The four backed all legitimate measures Riyadh takes to deter the threat and held the Houthis “fully accountable.” Pakistan and Türkiye are bound to Riyadh through the Mecca Defense Pact, though it’s not yet clear if they have committed to any offensive actions against the Houthis. Pakistan, which has deployed troops to Saudi Arabia, has insisted its role is defensive and has denied that its jets have been used in strikes against Yemen.

Secretary of State Marco Rubio condemned the “terrorist Houthis” for the strike, which killed an American citizen. Asked whether the U.S. would join Saudi strikes, President Trump said: “We may. We’re gonna look at it.”
