The United States has issued satellite images and cited intelligence to back its allegation Iran was behind attacks on major Saudi oil facilities.

Iran denies involvement in Saturday's air attacks, which were claimed by Iran-aligned Houthi rebels in Yemen.

The incident has cut global oil supplies by 5% and prices have soared.

 Dr Yossi Mansharof is an Iranian expert at The Jerusalem Institute for Strategic Studies (JISS) and the  Ezri Center for Iran & Persian Gulf Studies at the University of Haifa.

KAN's Mark Weiss  asked him if he was surprised by the attacks on the Saudi oil installations.
