King Khalid International Airport in Riyadh, the capital of Saudi Arabia, has been targeted in another attack resulting in a fire, just a day after a missile strike by Yemen's Iran-backed Houthi rebels killed 12 people.

Amid intense exchanges with the Houthi rebels, including powerful consecutive explosions echoing through downtown Riyadh, Saudi Arabia's national security crisis has reached its peak.

According to the Saudi-led coalition on the 11th (local time), an unidentified projectile struck Terminal 4 of King Khalid International Airport on this day, causing a fire.

The coalition stated that local authorities are directly conducting firefighting and cleanup operations, and added that Saudi air defenses separately intercepted a cruise missile in the airspace near the airport.

At least two powerful consecutive explosions were detected in the central and northern parts of Riyadh.

A resident in the Al-Arid district of northern Riyadh told the press about the extreme fear felt at the time, stating that birds flew away in a panic immediately after the explosion sound and the entire house shook.

The General Authority of Civil Aviation (GACA) of Saudi Arabia confirmed the new attack on King Khalid International Airport and announced that multiple injuries occurred.

The aviation authority added that it is assessing the scale of damage to airport facilities and conducting safety inspections in coordination with relevant authorities.

This series of attacks occurred just a day after a disaster the previous day targeting King Khalid Airport, where 12 multinational civilians—including four Saudis, two Bangladeshis, as well as individuals from the U.S., Egypt, and Jordan—were killed and about 300 others were injured.

The Houthi rebel attacks continued as Saudi Arabia was already in deep shock following the third airstrike targeting the Riyadh airport within the past week and the worst casualties in about a decade.

Authorities have completely suspended operations at Riyadh Airport for damage recovery and safety assessments, and urgently switched all in-person classes for students and faculty members in Riyadh to remote learning from the 11th through Thursday.

Yahya Saree, the military spokesman for the Houthi rebels, stated in a statement that in response to Saudi aggression, they successfully carried out four operations over the past 24 hours using ballistic and cruise missiles and unmanned aerial vehicles (drones).

He claimed that Saudi Arabia launched 124 airstrikes over the past 24 hours, and in retaliation, they struck King Khalid International Airport in three stages starting from the evening of the 9th, which paralyzed air traffic and completely closed the airport.

He also added that they accurately struck Aramco's Shaybah gas facility and Tanajib refinery in eastern Saudi Arabia, causing major fires, and also launched a direct strike on King Park International Airport in Dammam in the east, halting its operations.

Separately, Saree emphasized that they launched a precision strike using six ballistic missiles and two drones targeting Saudi troops gathered in the Ras al-Arah and Al-Sakiya areas, resulting in dozens of enemy casualties.

He also stated via X (formerly Twitter), "We reiterate our warning to all airlines, experts, airport workers, and travelers not to use Saudi airports and airspace."

They threatened, "Except for the airports in the Islamic holy sites of Mecca and Medina, Saudi airports are vulnerable to strikes and have become operational theaters for our military. You must take our warning seriously, and the sole responsibility for defense failure lies with Saudi Arabia."

On this day, the Houthi rebels also claimed that Sana'a International Airport in the Yemeni capital, which they control, was attacked once again by the Saudi-led coalition.

Al-Masirah TV, a broadcaster operated by the rebels, pointed to Saudi Arabia as the mastermind behind the attack without disclosing specific damage details.
