Early Saturday morning, two oil facilities in Saudi Arabia, Biqayq and Khurayṣ, were attacked by drones, temporarily halting oil production and slowing down natural gas production at the facilities.  Together, these two facilities produce 9.5 million barrels every day, over half of Saudi Arabia’s daily oil production.  The attack disrupted 5% of the world’s oil supply, causing oil prices to rise by 19%, the highest percentage seen since the first Gulf War in 1991.  Saudi Minister of Energy, ʿAbd al-ʿAzīz bin Salmān, said that they will begin compensating for the decrease in production and that Aramco is currently working to retrieve the lost amounts.
