Secretary of State Mike Pompeo traveled to Saudi Arabia where he told reporters the recent attack on the oil-rich nation was “and Iranian attack” and “an act of war.”

Pompeo said just before arriving in Jeddah: “It’s not the case that you can subcontract out the devastation of 5% of the world’s global energy supply and think that you can absolve yourself from responsibility. Were it the case that the Houthis’ fraudulent claim was accurate, were that true — it’s not, but were that true, it doesn’t change the fingerprints of the Ayatollah as having put at risk the global energy supply.”

Pompeo also said the rebels did not possess sophisticated weapons systems like the ones used in the attack.

Pompeo is in Saudi Arabia to “coordinate efforts to counter Iranian aggression in the region,”  according to a statement from the State Department.
