Iran live updates: 1 dead, 11 injured in attack on Saudi airport, officials say

The King Khalid International Airport in Riyadh, Saudi Arabia, was subject to a new attack on Sunday afternoon, according to the Saudi General Authority of Civil Aviation.

Officials said the attack resulted in injuries and assessments of the damage were ongoing in coordination with relevant authorities.

Maj. Gen. Turki Al-Maliki, spokesperson for the Saudi-led coalition in Yemen, said on social media that an "unknown projectile" had struck Passenger Hall No. 4 at King Khalid International Airport.

"A fire resulting from the attack is being directly handled by the competent authorities at the site," Al-Maliki said.

In a later post, Al-Maliki said Saudi air defenses had "destroyed a loitering (cruise) missile in the vicinity of King Khalid International Airport."

The new incident comes a day after a dozen people were killed and at least 300 were injured in an attack on King Khalid International Airport, the Saudi General Authority of Civil Aviation said. The Iran-backed Houthi rebels claimed responsibility for Saturday's attack. Secretary of State Marco Rubio confirmed that an American citizen was killed in Saturday's strike on the airport.

President Donald Trump on Saturday night told reporters that the attack on the King Khalid International Airport in Riyadh was "terrible" and that he would speak with Crown Prince Mohammed bin Salman.

“I think it's terrible,” Trump said of the attack.

Asked if the Saudis are able to defend themselves, Trump said: "Well, they're able to defend. Look, the Saudis are good fighters, but I think the attack was a terrible thing."

Later he said he had not yet spoken with bin Salman, but that he would, adding "What happened in Saudi Arabia is not acceptable."

U.S. Central Command said it disabled a commercial cargo vessel in the Gulf of Oman after the ship’s crew "ignored repeated warnings and attempted to run the ongoing naval blockade against Iran" on Saturday.

"A U.S. military fighter jet struck the stern of Panama-flagged M/V Ocean Molica (also known as the “Arika Sun”) with a precision munition, fully disabling the ship’s propulsion without harming the crew," CENTCOM said in a statement posted on social media.

Secretary of State Marco Rubio, in a statement posted on X, confirmed that an American citizen was killed in the strike on King Khalid International Airport in Saudi Arabia on Saturday.

Rubio said the United States "strongly condemns the recent attacks on the Kingdom of Saudi Arabia by the terrorist Houthis."

"These reprehensible attacks demonstrate a blatant disregard for innocent civilian life. They must stop now," he said. "We stand with the Kingdom of Saudi Arabia and its people and extend our condolences to the victims and their families."
