Riyadh Airport Struck Again on Sunday, Causing Injuries a Day After Attack Killed 13

A projectile struck Terminal 4 at King Khalid International Airport in Riyadh on Sunday, causing a fire and injuries, Saudi authorities said. The attack came one day after a missile strike on the same complex killed 13 people and wounded more than 300. The airport remained closed on Sunday while damage assessments continued.

The Saudi-led coalition reported that an unidentified projectile hit the passenger terminal. Air defences also intercepted a cruise missile near the airport. Saudi civil aviation officials said an unspecified number of people were injured and that they were still evaluating the damage and the safety of facilities. Operations at the airport that serves a city of eight million had already been suspended after Saturday’s attack.

Houthi military spokesman Yahya Saree claimed responsibility for Saturday’s strike and for additional operations in the past 24 hours. He said the group targeted the Riyadh airport multiple times, the airport in Dammam and two facilities belonging to Saudi Aramco. The Houthis renewed warnings to airlines, employees and travellers against using Saudi airports and airspace, describing them as a theatre of operations.

Saturday’s attack killed four Saudi nationals, two Bangladeshis, and one citizen each from the United States, Egypt, Jordan, Syria, Palestine and Sudan. An Indian national injured in the strike later died, bringing the confirmed death toll to 13. More than 300 people were wounded, some critically. It was the deadliest attack on a Gulf state since the broader regional conflict intensified earlier in the year.

The airport has been targeted repeatedly in the past week. Previous strikes killed four people and damaged a commercial aircraft on the tarmac. More than 600 flights were cancelled or diverted after Saturday’s hit. A long-planned international energy conference in Riyadh proceeded as scheduled on Sunday despite the continued threat.

President Donald Trump said the United States would look into whether to join Saudi military action against the Houthis after the Saturday attack. Saudi officials described the Saturday strike as a war crime and vowed a firm response. The Houthis have linked their attacks to Saudi airstrikes in Yemen, which they say have caused civilian casualties.

The Sunday projectile caused a fire inside Terminal 4. Videos from Saturday showed travellers walking through debris as sirens sounded. Radar and communications equipment were reported damaged, and runways required inspection. Flightradar24 data showed the closure extended into Sunday evening.

The escalation has raised the possibility of wider involvement. The conflict between the Houthis and the Saudi-backed Yemeni government has intensified after an earlier ceasefire unravelled. Attacks on civilian aviation infrastructure in the kingdom mark a significant expansion of the Houthis’ reach. South Korea raised its travel alert for Saudi Arabia to Level 3 after the Saturday strike.

Saudi authorities have not released a full casualty count for the Sunday incident. Damage assessments and safety checks continued as the airport remained shut. The Houthis’ claim of multiple simultaneous operations, including on energy facilities, indicates a coordinated campaign rather than isolated strikes.
