Im elaine quijano. World oil prices are expected to spike when trading opens this morning. A drone attack on two Oil Facilities cut the oil output in half. Rebels battle iing the saudis i yemen have claimed responsibility. The houthis are backed by iran, but the government says there it had nothing to do with the strikes. Nicole kiln yan reports from washington. Reporter one day after a drone attack hit the heart of south dako saudi arabias oil industry, they continued to put the blame on iran. The regime is responsible for this attack on the civilian areas and infrastructure vital to our Global Energy supply and were not going to stand for that. Reporter iran pushed back calling the accusations maximum lies and threatening they could strike mull tear bases in the middle east. The response follows a series of tweets saturday from secretary of state mike pompeo, who pointed the finger at tehran without proof. Despite Houthi Rebels claim of responsibility. Secretary pompeos statements were right. Its safe to say the houthis dont have the capability to do a strike like this without ir iranian assistance. Reporter saudi arabia says the attack cut the oil supply in half disrupting the production of 5. 7 Million Barrels a day. That has a warning oil prices could spike. This is a prolonged supply problem, then yes, we have a major hit to the markets. Reporter the Energy Department stands ready to tap into the oil reserves if necessary to offset any disruptions. Economits say the longer it takes for saudi arabia to recover, prices at the pump could increase by as much as 50 cents a gallon, though he says its unlikely. This is a temporary disruption. The only real threat is if we get into some conflict with iran over it. The white house says the president is still considering his options when it comes to potential talks with iranian president Hasan Rouhani at the general assembly, but it warns they arent helping the case with the saudi attack and will continue the maximum Pressure Campaign on iran, regardless of whether they meet.
