New Delhi: Saudi Arabia has reduced over half of its oil output following Saturday’s drone attacks which caused fires at two oil facilities of Saudi petroleum company Aramco, stated a report.

An official statement issued by Aramco noted that the drone attacks has suspended the production of 5.7 million barrels of crude which represents over half of Saudi Arabia’s oil output. This shortage in the global oil supply is likely to increase the oil prices once the trading resumes. The devastating strikes which were carried out by a fleet of 10 drones have also raked up the already prevalent tensions between Iran and the Persian Gulf.

While no one immediately claimed responsibility for the attack, media reports state that Yemen’s Houthi rebels have claimed responsibility for the drone attacks. An investigation in the incident is underway. According to Xinhua news agency, the drones attacked the two oil sites in Abqaiq and Khurais areas of Saudi Arabia.

The Saudi Embassy tweeted on Saturday, “The Joint Forces Command of the Coalition to Restore Legitimacy in Yemen: Investigations Ongoing in the Terrorist Attack Against Two Saudi Aramco Facilities to Identify Parties Involved in the Attack.”

Speaking to the Saudi Press Agency, spokesperson of Saudi-led Coalition Turki Al Maliki had said, “The coalition continues to adopt and implement necessary procedures to deal with such terrorist threats in order to safeguard national assets, international energy security and ensure the stability of the world economy.” The coalition has announced to launch a probe in the drone attacks soon.

Last month, a similar attack was carried out by Yemen’s Huthi rebels, which sparked fire at Aramco’s Shaybah natural gas liquefaction facility.
