Yemen’s Houthi group said on Sunday that it had targeted King Khalid International Airport, Aramco oil storage tanks and the financial centre in Riyadh, Saudi Arabia’s capital, Xinhua reported. Earlier in the day, an administrative building belonging to state oil giant Saudi Aramco in Riyadh was damaged by falling debris following an attempted attack on Sunday, with no injuries or fatalities reported, the kingdom's Energy Ministry said. A Reuters witness saw blown-out windows across several floors of the Aramco Tower, one of the tallest buildings in the capital's King Abdullah Financial District. The incident, which the ministry said caused limited damage, came after the Saudi-led coalition said it had intercepted two missiles fired by Yemen's Houthis towards Riyadh. Aramco was not immediately available for comment, and there was no immediate statement from the Houthis. Multiple loud booms were heard in Riyadh earlier on Sunday, a Reuters witness said, shortly after Saudi Civil Defence issued an early-warning alert of a potential threat in the region. Authorities later announced that the danger had passed. The Saudi-led coalition that has been fighting the Houthis subsequently said it had intercepted and destroyed two cruise missiles in Riyadh and the kingdom's southern region. Alerts in oil-rich eastern province Earlier on Sunday, Saudi Civil Defence issued and later lifted warnings in several areas of the oil-rich Eastern Province, including Dhahran, home to the headquarters of state oil giant Saudi Aramco. The Eastern Province holds most of the kingdom's oil and gas reserves. Saudi Aramco's headquarters suffered extensive damage in an attack in October. An attack on Riyadh's King Khalid International Airport on October 10 killed 13 people and wounded more than 300, according to Saudi authorities. The renewed hostilities have shattered a 2022 UN-brokered truce that had largely halted fighting between the two sides. Saudi Arabia led a coalition of Arab states into Yemen in 2015 to restore the internationally recognised government after the Houthis seized the capital, Sanaa. The latest escalation comes a day after Yemen's Houthi-run health ministry said Saudi airstrikes killed at least 33 people near Sanaa. Saudi authorities said they were investigating. Houthi-run health ministry says airstrikes kill 33 near Yemen capital At least 33 people were killed and 39 wounded in what the Houthi-run Saba news agency said were Saudi airstrikes on a village near Yemen's capital Sanaa on Saturday, in one of the deadliest reported attacks since fighting between Saudi Arabia and the Iran-aligned group resumed in July. Reuters could not independently verify the account. Saudi Arabia's Center for International Communication said it was investigating the report. The renewed fighting between Saudi Arabia and the Houthis has shattered a 2022 UN-brokered truce that largely halted attacks between the Saudi-led coalition and the group, which controls Sanaa. The Houthis have since launched missile and drone attacks on Saudi airports and oil facilities, while Riyadh has carried out airstrikes in Yemen in support of its Yemeni allies. The ministry said the strikes hit homes in the town of Bani Hushaysh, a Houthi stronghold east of Sanaa, and that most of those killed were women and children. Abdul-Aziz al-Dailami, director of Sehatuna Hospital in Sanaa, said many victims remained trapped under the rubble, including first responders. "The strikes keep coming. Just as rescuers arrive, another strike hits. We have even lost some of our own medical responders, who have been martyred," he told Reuters. "We received a number of wounded individuals in very critical condition, with injuries to the head, chest and legs, as well as fractures," al-Dailami added. Yemeni army says it carried out over 800 operations against Houthis Yemeni government forces said on Saturday that they carried out 875 operations against the Houthis in recent hours, claiming to have killed or incapacitated 130 fighters and commanders. Military spokesman Majed al-Nazili said in a statement on the X that the operations targeted Houthi positions, reinforcements and military equipment as part of Operation Dawn of Yemen. He said warplanes, drones, and artillery supported the operations, which destroyed or damaged 50 military vehicles and pieces of equipment, including missile launchers. In southwestern Taiz province, government troops and allied Popular Resistance fighters continued to repel Houthi attacks and target the group’s positions and movements. Other units attacked Houthi positions and reinforcements in Marib and Al-Jawf provinces. The army also reported continued operations by government-aligned forces on southern and western fronts. The military said its forces were taking precautions to protect civilians and civilian infrastructure. The Houthis did not immediately comment on the Yemeni military’s statement.
