“The Secretary of State is traveling to Saudi Arabia today to discuss our response,” he said during a speech.
On September 14, Saudi Aramco refineries in eastern Saudi Arabia were attacked by drones. The responsibility for the attack was claimed by the Hussite Yemeni rebels.
The Arab coalition fighting in Yemen, led by Saudi Arabia, accused Iran of attacking the kingdom's oil facilities. US Secretary of State Mike Pompeo also blamed Iran.
US Senator Lindsay Graham called for Iranian refineries to be included in the list of targets for a possible military “response” to the incident.
