DUBAI — An attack on King Fahd International Airport in Dammam on Wednesday evening killed one person and injured eight, Saudi Arabia's civil aviation authority said, hours after debris from a drone shot down over Saudi Aramco's Shaybah oil field killed two foreign residents.

The two incidents in the Eastern Province brought Wednesday's death toll to three after a month of near-daily attacks on the kingdom, which Saudi officials blame on Yemen's Iran-backed Houthi movement. Washington has now told non-emergency government staff to leave the country.

The General Authority of Civil Aviation (GACA) announced the airport casualties early on Thursday. It said injuries ranged from minor to critical and that the attack had also caused material damage, which was still being assessed.

"All injured individuals were immediately transported to hospital to receive the necessary medical care," the authority said, adding that further updates would follow. It did not say what kind of weapon struck the airport or who launched it.

Flight-tracking service Flightradar24 showed no operations at the airport since about 11.15pm local time on Wednesday, Khaleej Times reported, though Saudi authorities had not formally announced a suspension.

The Shaybah incident happened earlier on Wednesday. The energy ministry said air defences had intercepted a drone heading for a processing facility at the field.

"The attempted attack resulted in the deaths of two individuals, a Filipino and a Nepali, and injuries to two others," the ministry said, identifying the injured as a Pakistani and an Indian resident. Falling debris set fire to a contractor's vehicle outside the facility's perimeter, but the ministry said oilfield operations were not affected.

The Indian embassy said it was in contact with Saudi authorities and awaiting further details. "We will provide all necessary help to the injured Indian national," it said.

The ministry did not say who launched the drone. The Saudi-led coalition fighting in Yemen said it shot down several drones aimed at the kingdom on Wednesday, including over the Madinah region, and attributed at least one of them to the Houthis.

The coalition said early on Thursday that four more drones had been shot down over the Eastern Province. Its spokesman, Maj. Gen. Turki Al-Maliki, wrote in one of several posts on X that "Four drones launched towards the Kingdom have been intercepted and destroyed."

No group had publicly claimed the Dammam or Shaybah attacks in the reports reviewed by Strait. The Houthis have repeatedly targeted Saudi airports this month, including a strike on the same Dammam airport on October 11, according to Anadolu Agency.

The United States has ordered non-emergency government staff and their families to leave Saudi Arabia. State Department spokesman Tommy Pigott said on social media that "Iranian-supported Houthis have increasingly engaged in hostilities against Saudi Arabia," including strikes on civilian airports and critical infrastructure.

A State Department spokesperson told The Hill that "the hostilities have the potential to escalate rapidly, including beyond that immediate area." An unnamed diplomatic source said some families of US embassy staff were also being withdrawn from the UAE, Jordan, Qatar and Bahrain, RTE reported, although Pigott said the order applied only to Saudi Arabia.

The attacks came as Saudi Foreign Minister Prince Faisal bin Farhan hosted his Jordanian counterpart, Ayman Safadi, in Riyadh on Wednesday. According to Asharq Al-Awsat, the two discussed the continued Houthi attacks on Saudi territory, and Safadi expressed Jordan's solidarity with the kingdom.

The violence follows the collapse in June of a four-year-old truce in Yemen's civil war. The conflict dates to 2014, and a Saudi-led coalition has backed Yemen's internationally recognised government since 2015.

Earlier this month an attack on King Khalid International Airport in Riyadh killed 12 people, the deadliest on the kingdom in years, according to RTE. Khaleej Times reported that a second attack on the capital's airport killed one more person.

Faisal and Safadi also discussed the safety of shipping through the Strait of Hormuz and Bab al-Mandeb, Asharq Al-Awsat reported. GACA had not said when flights at Dammam would resume.
