An official speaking on behalf of the Aden Oil Refinery stated that the oil refinery has resumed operation after nine months\' stoppage caused by bandits\' attacks on Yemen\'s main oil pipeline. The official told Reuters that two crude oil shipments arrived via Ras Isa harbor on the Red Sea which provided the refinery the opportunity to resume its operations, pointing out that the refinery will work at low capacity of 60,000 barrels per day. He asserted that the refinery will, with the arrival of weekly shipments from Ras Isa Harbor, continue to produce 600,000 barrels/day. Tribal militants had mounted attacks on Yemen\'s key oil pipeline which led its suspension of pumping crude oil last year and led to shutting down the refinery which has a production capacity of 150,000 barrels/day of refined oil products. Yemen, then had to rely on Saudi fuel supplies and imported refine oil products. The Yemeni Oil Ministry also asserted that the long halting of the refinery had cost the country about USD 15 million per day in lost revenues. Oil and gas pipelines in Yemen have been subjected to recurrent attacks in the aftermath of anti-government protestation which left a power vacuum since 2011.
