Just before US Secretary of State Mike Pompeo landed in Jeddah, Saudi Arabia, on Wednesday, he described the strikes on key Saudi oil installations as an “act of war,” reiterating that it was an “Iranian attack.”

“This was an Iranian attack,” he told reporters on his plane, calling it “an act of war.”

He added there was no evidence the attacks had been launched from Iraq, amid media speculation the drones had been fired from there.

Pompeo is scheduled to meet with Saudi Arabia’s Crown Prince Mohammed bin Salman to discuss the recent attack on two Saudi Arabian oil facilities and coordinate efforts to counter Iranian aggression in the region.

Pompeo will later travel to the United Arab Emirates on Thursday to meet with Abu Dhabi's powerful crown prince, Sheikh Mohammed bin Zayed Al Nahyan.
