The Houthi ​group in Yemen said ‌on Monday it had attacked Saudi Arabia's East-West crude ​oil pumping stations ​and Riyadh airport, but there ⁠was no immediate ​Saudi confirmation. The Saudi-led coalition in ​Yemen said earlier it had destroyed two ballistic missile launchers in ​the capital Sanaa, ​including one used to fire a ‌missile ⁠towards Riyadh that the coalition said it had intercepted. The Houthis have been ​firing ​ballistic ⁠missiles and drones at Saudi airports, ports ​and oil installations, ​turning ⁠US ally Saudi Arabia into a pressure point ⁠in ​the wider war. Saudis say Riyadh airport partly reopens despite renewed Houthi threats Saudi Arabia said its main airport resumed operations at two terminals ​on Sunday even as Yemen's Iran-aligned Houthis vowed to keep striking the facility, which they called a "military target". King ‌Khalid International Airport in Riyadh had halted operations on October 10 following an attack claimed by the Houthis that killed 13 people, the deadliest in the kingdom in more than a decade. Saudi Arabia said it intercepted another wave of missiles and drones on Sunday as fighting with the militant group continued unabated. The Houthis ​said they had launched attacks on the air hub among other sites in the kingdom, including in Khamis Mushait ​and Jazan. It was not immediately clear if those were the strikes the kingdom said it had ⁠blocked. The conflict has become an increasingly destabilising element in the US-Israeli offensive against Iran, turning US ally Saudi Arabia into a pressure ​point in the wider war. Flight tracking data shows little traffic After Saudi authorities announced the partial resumption of operations at the airport, Houthi ​military spokesperson Yahya Saree vowed the facility would "never be safe" and urged airlines, airport staff and travellers not to use it. Late on Saturday, the airport said it would designate Terminal 1 for domestic flights and Terminal 2 for international flights operated by national carriers starting Sunday. Despite the announcement, Flightradar24 data showed little traffic at the airport on Sunday. The Saudi-led coalition said earlier this month that the Houthis had ​carried out 20 attacks on the airport between October 1 and 11. Missile and drone attacks continue Saudi civil defence said on Sunday that shrapnel from ‌the interception ⁠of two ballistic missiles launched by the Houthis over Khamis Mushait and Ahad Rafidah injured two people and damaged residential buildings and vehicles. Civil defence authorities earlier issued emergency alerts for Riyadh and the cities of Abha, Khamis Mushait, Jazan and Najran on Sunday, before saying minutes later that the danger had passed. The coalition said two drones and a ballistic missile were launched towards Riyadh, and a ​cruise missile towards the southern city ​of Khamis Mushait. It ⁠later said it intercepted 10 ballistic missiles fired towards southern Saudi Arabia. The Houthis said they attacked the airport and Saudi oil facilities on Saturday. Saudi authorities did not comment directly on the Houthi statements. Saudi ​Arabia has stepped up its strikes against the Houthis after the group seized strategic territory along ​the Red Sea ⁠coast last month, closing in on the Bab el-Mandeb Strait – a global maritime chokepoint and shipping route for Gulf oil producers on the opposite side of the Arabian Peninsula to the Strait of Hormuz. The renewed fighting in Yemen has shattered a UN-brokered truce that had largely ⁠held since ​2022. Saudi Arabia intervened in Yemen's civil war in 2015 at the head ​of a coalition supporting the internationally recognised government, after the Houthis seized the capital Sanaa a year earlier.
