Huge plumes of black smoke could be seen coming from the Abqaiq oil facility in Bugayg, Saudi Arabia (pictured). Satellite images show the infernos raging at the plant in as well as the country's second largest oilfield in Khurais yesterday morning after Tehran-backed Houthi rebels in Yemen fired a flurry of rockets. Iran dismissed US accusations it was behind the drone attack as 'meaningless'. Saudi Arabia's energy minister has confirmed the attacks on its oil facilities on Saturday knocked out about 50 per cent of the country's production and said it will make up for some of the loss with oil stocks.
