An attack on King Fahd International Airport in Dammam, Saudi Arabia, on Wednesday evening killed one resident and injured eight others, the General Authority of Civil Aviation said.

The statement said material damage was being assessed.

Earlier in the day, two people were killed after Saudi air defences intercepted a drone that was attempting to hit a facility at Saudi Aramco's Shaybah oilfield, the energy ministry said.

The US State Department, before the attacks, ordered some diplomats and family members to depart from its missions in Saudi Arabia and plans to withdraw family members from a number of other US missions in the region, US officials told Reuters.

State Department spokesperson Tommy Pigott said in a post on X that the department ordered the departure of "non-emergency US government employees and their family members in Saudi Arabia only" amid attacks by the Iran-aligned Houthis in Yemen on civilian targets in the country.

Washington had returned some diplomatic personnel to the region in recent months after many were pulled out when Tehran launched attacks on US facilities after the US-Israeli war on Iran began in late February.

"Iranian-supported Houthis have increasingly engaged in hostilities against Saudi Arabia, including attacks on civilian airports and other critical infrastructure resulting in civilian casualties and severe travel disruptions," Pigott said.

Four US officials told Reuters that US missions in other Gulf states would also be ordering family members to leave. Pigott did not address changes to other missions outside Saudi Arabia.

The latest withdrawals follow an escalation of the fighting in Yemen, opening another front in the regional conflict triggered by the US-Israeli ⁠war on Iran. The wider conflict has snarled global energy trade and hurt Gulf economies.

The US embassy in Riyadh issued a security alert on Wednesday about possible further attacks by the Houthis on Saudi Arabia, after recent deadly strikes including on Riyadh's airport.

The embassy and a CIA station hosted there came under attack by drones in early March, as Iran began launching attacks across the region.
