The death toll from two successive attacks on King Khalid International Airport in Riyadh has risen to 14, after another person was killed in a fresh strike on Sunday, according to Saudi authorities.
Reuters reported that Sunday's attack killed one person and injured 11 others, just a day after a deadly assault claimed by Yemen's Houthi movement. Saturday's attack left 13 people dead and more than 300 injured, according to the latest official figures. The victims included four Saudi nationals and several foreign citizens.
The death toll from Saturday's attack increased after an Indian national who had been wounded succumbed to his injuries.
Fresh strike hits terminal
According to Reuters, the Saudi-led coalition said an unidentified projectile struck Terminal Four at Riyadh's international airport on Sunday, sparking a fire.
Saudi Arabia's General Authority of Civil Aviation confirmed one fatality and 11 injuries, adding that the extent of the damage to airport facilities was still being assessed.
Saudi air defences also intercepted a cruise missile near King Khalid International Airport, while a drone was detected and destroyed in the Eastern Province. Coalition forces further reported intercepting a ballistic missile launched towards the Khamis Mushait area.
Houthis warn of more attacks
The Iran-backed Houthis claimed responsibility for Saturday's mass-casualty attack and repeated warnings to airlines and travellers to avoid Saudi airports.
According to Reuters, the group also claimed responsibility for strikes targeting King Fahd International Airport in Dammam and two facilities belonging to Saudi Aramco.
The escalation has heightened concerns over the safety of air travel in the kingdom, prompting authorities to increase security measures.
Flight warnings issued
The attacks caused significant disruption to air travel, with flight cancellations and delays reported.
Reuters said the US Federal Aviation Administration (FAA) issued an advisory urging American airlines to exercise increased caution when operating flights to or over Saudi Arabia, citing risks linked to ongoing military activity and potential interference with navigation systems.
At the same time, Saudi authorities ordered schools in Riyadh to switch to remote learning from Sunday through Thursday because of the deteriorating security situation.
Tensions continue to rise
The latest attacks come amid worsening tensions between Saudi Arabia and the Houthis.
Riyadh has intensified military operations against the Yemeni group, while the Houthis have threatened further strikes if Saudi military action continues.
"The worst is yet to come," the group warned, according to Reuters.
Reuters reported that attacks on Riyadh airport over the past week have now claimed a total of 18 lives.
The latest escalation is raising fresh concerns about the security of Saudi Arabia's airports and energy infrastructure, as well as the wider impact of the conflict on international air travel.
