On Saturday, Saudi Arabia was forced to shut down two Saudi Aramco oil facilities, namely Abqaiq and Khurais, after a drone attack, claimed by Yemeni Houthis, caused massive fires. The incident led to a cut in oil production totalling 5.7 million barrels per day — about half of Saudi Arabia’s daily oil output.
"As the investigations are ongoing, the Kingdom will invite UN and international experts to view the situation on the ground and to participate in the investigations," the ministry said on Twitter.
Riyadh also called on the international community to "take a firm and clear position against this reckless behaviour that threatens the global economy."
Houthi rebels regularly conduct drone attacks on facilities in Saudi Arabia, which has been providing air support to Yemen’s internationally recognized government in its fight against Houthis since spring 2015. At the same time, US officials have claimed that intelligence indicates Iranian involvement in the incidents. Iran firmly denied any involvement.
