Houthi statement from Sanaa claims three operations against Saudi Arabia with ballistic and cruise missiles and drones.
King Khalid Airport in Riyadh was hit and air traffic disrupted. The Aramco refinery in Rabigh was hit and set on fire. Abha Airport, the Khamis Mushait airbase, the Aqeefah camp in Asir and sites in Najran and Jizan were also hit.
The Houthis say the attacks answer 60 Saudi airstrikes on Sanaa, Al-Jawf, Taiz, Hodeidah, Saada and Marib in the past 24 hours.
Airlines were warned to halt flights through Saudi airspace, with Mecca and Medina excluded.
