DOHA (Al Jazeera) — The drone attacks claimed by Yemeni Houthi rebels have caused fires in two main facilities managed by Saudi Aramco, the Saudi state-owned oil giant.

Quoting a spokesperson for the Ministry of Interior, the Saudi news agency announced on Saturday that the fires at the Abqaiq facility — home to the company’s largest oil refinery — and that at Khurai were under control. The Ministry did not identify the source of the attack and stated that investigations were ongoing. He did not specify whether there had been any casualties or whether operations at both facilities had been affected.
