Oil prices have surged amid fears that Saudi Arabia could run out of export stocks in a matter of days if it does not repair a bombed pipeline.Satellite images have revealed the extent of the damage to the 745-mile east-west oil pipeline after drones were launched from Iraq on Thursday, with a pumping station appearing badly charred.Oil prices rose ‌more than 3 per cent on Monday, following 'a step-up in attacks ​on Saudi Arabian energy infrastructure, including targeting the crucial east-west pipeline,' said ING commodity ⁠strategists.The pipeline has helped Saudi Arabia - the world's largest crude oil exporter - bypass the Strait of Hormuz by re-routing around 4million barrels a day to the port of Yanbu on the Red Sea.Riyadh decided to shut the key pipeline following the attack, threatening the loss of 4 per cent of global supplies and driving the price of crude higher. If the pipeline remains shut, existing stocks at Yanbu could only support exports for around five to seven days, industry sources told Reuters.The global energy market is already under severe strain after the Iran war triggered the closure of the Strait of Hormuz, through which a fifth of the world’s oil and gas normally flows. Fresh fears of global oil supply chaos came as Donald Trump told Ukrainian President Volodymyr Zelensky that he 'has to stop knocking out diesel fuel in Russia'.
