Yemen's Houthi movement has said it carried out an attack on an airport in eastern Saudi Arabia on Wednesday evening, which Saudi authorities said killed two people and injured eight others.
The Saudi General Authority of Civil Aviation identified those killed at King Fahd International Airport in Dammam as a Saudi citizen and an Indian resident. It did not say what type of attack occurred, but the Iran-backed Houthis said on Thursday that the airport was one of the sites they had targeted with drones and missiles over the previous 48 hours.
Two more people were killed on Wednesday morning by debris from a drone that was intercepted elsewhere in Eastern Province, the Saudi energy ministry said. The drone was intercepted as it attempted to target a processing facility owned by state oil company Aramco in the Shaybah oil field, where a contractor's vehicle was set ablaze. The ministry identified the dead as residents from the Philippines and Nepal. The Houthis' military spokesman, Yahya Sarea, did not claim the attack on the oil field.
Sarea said the group had targeted the Saudi defence ministry headquarters in Riyadh, an Aramco facility in Yanbu, and Abha International Airport, in addition to Dammam. The Saudi-led coalition said it intercepted four drones over Eastern Province on Wednesday night, and four more over Riyadh and Medina on Thursday.
At least 21 people have now been killed in Houthi attacks on Saudi airports since the start of October, according to Saudi authorities. The deadliest was a missile strike on Riyadh's international airport on 10 October, which killed 13 people and injured 308 others.
The escalating violence has drawn an international response. The United Kingdom has announced it will deploy jets to defend Saudi Arabia, and the United States has ordered some diplomats to leave the country.
On the ground in Yemen, the fighting continues. Houthi-run media reported at least six people killed and 11 injured in air and artillery strikes over the previous 24 hours. The Houthi-run health ministry says 155 civilians have been killed since the conflict escalated three months ago. The government's health ministry has put the death toll over the same period at 1,574, while the fighting has displaced more than 256,000 people.
