Coalition spokesman Major-General Turki al-Maliki announced the thwarted attack on X, days after two separate strikes hit Riyadh’s King Khalid International Airport, killing 14 people and injuring more than 300 others. A Houthi attack on Abha International Airport killed two more people.
The Houthis, also known as Ansar Allah, claimed they targeted facilities of Saudi Arabia's national oil company Aramco in Dhahran, an Aramco refinery in Riyadh, and the capital's airport. Overnight, the Saudi Ministry of Energy confirmed that the administrative building belonging to Aramco in Dhahran was hit.
The General Directorate of Saudi Civil Defence issued two alerts through its national early warning platform, later saying the danger had passed. One alert was for the Al-Kharj governorate in Riyadh province, and the other for the capital.
Al Jazeera's Zein Basravi, reporting from Doha, said any notion that the Saudi-led coalition could contain the conflict to Yemen has been shattered over the last 10 days.
Meanwhile, Saudi-backed Yemeni government forces have launched a counteroffensive in Yemen to retake coastal territory near the Bab al-Mandeb strait, a vital maritime trade chokepoint at the entrance to the Red Sea. Fighting between the Iran-aligned Houthis and Saudi-backed Yemeni government forces escalated sharply last month, ending the UN-brokered ceasefire.
The Houthis have controlled Yemen's most populous areas, including the capital Sanaa, since seizing the city in 2014, forcing the internationally recognised government to flee to southern Yemen.
The Muslim World League on Wednesday condemned the continued Houthi attacks on Saudi Arabia, saying they deliberately target civilians and civilian sites. League secretary-general Sheikh Mohammad bin Abdulkarim Al-Issa said the nature of the attacks confirms the criminal approach of the group.
