In a statement issued Thursday, Saudi Arabia’s General Authority of Civil Aviation identified the victims as a Saudi citizen and an Indian resident.

The aviation authority also confirmed that eight other people were injured in the attack on the airport, located in the country’s Eastern Province.

The latest figures represent an increase from the initial death toll reported shortly after the incident.

The airport attack came on the same day as another deadly incident involving a drone targeting Saudi Arabia’s energy infrastructure.

According to the Saudi Ministry of Energy, two people were killed after the country’s air defense systems intercepted a drone attempting to strike a facility at Saudi Aramco’s Shaybah oil field.

The incident adds to a series of attacks on critical infrastructure as fighting intensifies between Houthi forces and Yemen’s internationally recognized government, which is backed by Saudi Arabia.

The continued assaults have heightened concerns about the security of airports, energy installations and other strategic facilities across the kingdom.

The latest violence follows two major incidents at King Khalid International Airport in the Saudi capital, Riyadh, earlier this month.

On October 11, Saudi authorities reported that a projectile strike killed one person and injured 11 others.

A day earlier, on October 10, a separate attack on the same airport reportedly killed 12 people and left more than 300 injured.

The repeated incidents have raised concerns about the increasing threat to civilian aviation and the potential consequences for regional travel and economic activity.

The deteriorating security situation has also prompted the United States to take precautionary measures to protect its diplomatic personnel.

On Wednesday, the U.S. State Department ordered the departure of designated diplomatic personnel and family members from its missions in Saudi Arabia, citing the growing threat of Houthi attacks.

U.S. officials also told Reuters that Washington was considering withdrawing family members from additional diplomatic missions elsewhere in the Middle East.

The American Embassy in Riyadh issued a security alert Wednesday, warning of the possibility of further Houthi attacks on Saudi territory.

The alert reflects increasing concern among foreign governments about the safety of their citizens and personnel as the regional conflict continues.

The latest attacks underscore the mounting security challenges facing Saudi Arabia as hostilities involving Houthi forces continue.

With airports and oil facilities increasingly exposed to potential attacks, Saudi authorities face growing pressure to strengthen defensive measures and protect civilian infrastructure.

The violence has also raised concerns about possible disruptions to international travel, energy supplies and regional economic stability.

As investigations continue into the incidents in Dammam and at the Shaybah oil field, authorities remain on heightened alert for further threats.

The escalating attacks, combined with new diplomatic security restrictions, highlight the increasingly fragile security situation in the region.
