RIYADH/SANAA/TEHRAN – A Pakistani resident was killed and 11 others injured in an attack targeting King Khalid International Airport Sunday afternoon, Saudi Arabia's General Authority of Civil Aviation (GACA) said Monday.

GACA said on its official account on X that the attack claimed the life of a Pakistani resident and left 11 others injured, and the latter were immediately transferred to hospital for medical treatment.

The attack also caused material damage, the extent of which is still being assessed, the agency said.

Fighting between Yemen's Houthis and the Saudi-led coalition showed no sign of easing on Sunday as fresh attacks hit major airports in Saudi Arabia, while the Houthi group claimed new missile and drone operations against Saudi airports and energy facilities and the coalition vowed a firm response.

Earlier on Sunday, the Saudi-led coalition said an unknown projectile had struck a passenger terminal at the King Khalid International Airport, and a fire resulting from the attack was being handled at the site.

In a later statement, GACA said King Fahd International Airport near Dammam in the Eastern Province was attacked on Sunday evening, with damage assessments and safety inspections of the airport facilities underway.

The Houthi group claimed it had carried out four missile and drone operations against airports and energy facilities across Saudi Arabia over the past 24 hours.

Houthi military spokesperson Yahya Sarea said the operations targeted King Khalid International Airport, King Fahd International Airport, and two facilities operated by Saudi energy giant Aramco.

In a separate statement, Sarea warned that Saudi airports and airspace, except for the airports in the Islamic holy cities of Mecca and Medina, remained "exposed to targeting" and constituted an area of operations for the group's forces.

Meanwhile, Saudi airstrikes continued across Houthi-held areas in Yemen, as the Saudi-led coalition vowed to respond firmly to the Houthi strikes.

Sarea claimed Saudi warplanes had carried out 124 strikes over the previous 24 hours targeting the capital Sanaa and the provinces of Taiz, Marib, Al-Jawf, Hajjah, Hodeidah and Saada.

Houthi-run al-Masirah TV also reported earlier on Sunday that a Saudi airstrike hit Sanaa International Airport in Yemen's Houthi-held capital, with no immediate information on casualties or damage at the airport.

A Yemeni military official told Xinhua that Saudi warplanes had launched intensive strikes on Houthi-controlled areas in the southwestern province of Taiz, where fierce fighting between government forces and the group has intensified.

The escalating conflict has drawn growing international concern, particularly after a Houthi attack on King Khalid International Airport on Saturday killed 12 people and injured 309 others.

"I am deeply shocked by and strongly condemn Saturday's lethal attack by the Houthis on King Khalid International Airport in Riyadh," said United Nations (UN) Secretary-General Antonio Guterres, adding that attacks on civilians and civilian infrastructure violate international law and "must cease immediately."

Tehran says ready to help initiate dialogue

Iran's Foreign Minister Seyed Abbas Araghchi on Sunday voiced his country's readiness to provide any kind of assistance to help initiate dialogue between Saudi Arabia and Yemen and prepare the ground for achieving a political solution to the ongoing conflict.

He made the remarks in a phone call with his Saudi counterpart Prince Faisal bin Farhan bin Abdullah Al Saud, in which the two sides discussed the ongoing developments in the West Asia region, according to the official news agency IRNA.

Araghchi expressed grave concern over the escalation of tensions, saying insistence on pursuing military approaches and turning a blind eye to political solutions solely further complicate the status quo.

He stressed that there is no military solution to the crises in West Asia.

Arab nations, Türkiye, Israel condemn Houthi attack on Riyadh airport

The United Arab Emirates, Sudan, Egypt, Türkiye, Israel, Iraq, Syria, Palestine, Bahrain and the Arab League also condemned Saturday's attack.

Israeli Prime Minister Benjamin Netanyahu condemned "in the strongest possible terms the horrific terrorist attack" on the social media platform X.

Yemen has been mired in conflict since late 2014, when the Houthis seized the capital Sanaa and much of the country's north. A Saudi-led coalition intervened in 2015 in support of the internationally recognized Yemeni government, now based in the southern port city of Aden.

The renewed fighting marked a major escalation after a UN-brokered truce in 2022 largely halted major hostilities.
