Saudi Arabia faced renewed missile and drone attacks on Monday as authorities extended the closure of Riyadh's King Khalid International Airport until October 17, following deadly strikes claimed by Yemen's Iran-aligned Houthis.
The escalating attacks have disrupted international flights, heightened regional security concerns and complicated Saudi military operations in Yemen.
Saudi aviation authorities confirmed that the airport would remain closed until 2100 GMT on Saturday to complete safety and operational readiness procedures.
The suspension follows Saturday's missile strike on a departure terminal that killed 13 people and injured more than 300.
Another attack on Sunday killed one person and wounded nearly a dozen others.
Late Monday, the Houthis claimed another ballistic missile attack against the airport, shortly after Saudi authorities announced intercepting and destroying a missile targeting Riyadh.
The group also claimed a drone strike against an airbase in Khamis Mushait, although Saudi officials did not immediately confirm that attack.
Aviation analytics firm Cirium reported that cancellations across Saudi airports reached 46.4%.
Lufthansa suspended Riyadh services until October 16, while Air France-KLM extended its suspension through October.
Etihad Airways also prolonged cancellations, and Delta postponed its planned Atlanta-Riyadh service until March 2027.
The attacks come as Saudi Arabia intensifies operations against Houthi forces in Yemen, seeking to secure the strategically important Bab el-Mandeb shipping route.
Saudi-backed Yemeni forces have made limited gains around the strait but remain under pressure elsewhere.
Saudi airstrikes reportedly struck Yemen's al-Jawf province on Monday, while Iran offered to facilitate dialogue between Riyadh and the Houthis.
The United Arab Emirates called for renewed Gulf security cooperation, warning that attacks against Saudi Arabia threatened regional stability.
Meanwhile, US President Donald Trump said Washington was considering participating in strikes against the Houthis, although no American action had been reported.
The crisis has also overshadowed major energy and investment gatherings in Riyadh.
Saudi Energy Minister Prince Abdulaziz bin Salman nevertheless reaffirmed the kingdom's commitment to industrial development and investment.
