Passenger terminal in Riyadh airport hit again, a day after deadly strike killed 12

Yemen's Houthis issued a new threat to Saudi Arabia's airspace on Sunday after an attack on the kingdom's international airport in Riyadh killed at least 12 people, including a U.S. citizen, and wounded hundreds of others. Hours later, a Saudi-led coalition fighting Houthis in Yemen said a projectile struck a passenger terminal at King Khalid International Airport in Riyadh.

Saturday's strike at the airport, the deadliest on Saudi soil in more than a decade, marked a major escalation in the war between Yemen's Iran-backed Houthis and the kingdom and further complicated sputtering efforts to halt the U.S.-Iran war.

While the Houthis did not immediately claim Saturday's deadly strike, they threatened new attacks on the kingdom's airports, except for the holy sites of Mecca and Medina, warning passengers not to travel.

On Sunday, the Houthis said the airport under their control in the Yemeni capital of Sanaa had been struck again. They blamed the Saudis but provided no details.

"The United States strongly condemns the recent attacks on the Kingdom of Saudi Arabia by the terrorist Houthis, including today's strike on King Khalid International Airport in Riyadh that took numerous innocent lives, including an American citizen," Secretary of State Marco Rubio said in a social media post.

European Commission President Ursula von der Leyen said the attacks by Iran's proxies are "pushing the region into a spiral of violence."

Israeli Prime Minister Benjamin Netanyahu on Sunday condemned "in the strongest possible terms" the attack on King Khalid Airport and extended his condolences.

The attack struck an airport complex housing terminals 3 and 4 for domestic flights, a regional official said, speaking on condition of anonymity because they weren't authorized to speak to the media.

The Egyptian woman was a flight attendant identified as Azza Ramzy, 28, who worked for the Saudi airline Flynas, according to the Egyptian state-run Al-Qahera News television.

The Houthis claimed attacks earlier in the week on King Khalid International Airport that killed three Saudis, including a pilot. The airport has no military facilities.
