Saudi Arabia has cut oil and gas production following drone attacks on two major oil facilities run by state-owned company Aramco.Energy Minister Prince Abdulaziz bin Salman said the strikes had reduced crude oil production by 5.7m barrels a day - about half the kingdom's output, reports BBC.
A Yemeni Houthi rebel spokesman said it had deployed 10 drones in the attacks.
US Secretary of State Mike Pompeo blamed the attacks on Iran saying there was no evidence they came from Yemen.
The Saudis lead a Western-backed military coalition supporting Yemen's government, while Iran backs the Houthi rebels.
In a statement carried by the Saudi Press Agency (SPA), Prince Abdulaziz said the attacks "resulted in a temporary suspension of production at Abqaiq and Khurais plants".
He said that part of the reduction would be compensated for by drawing on Aramco's oil stocks.The situation was under control at both facilities, Aramco CEO Amin Nasser said, adding that no casualties had been reported in the attacks.
