Pompeo meets King Salman, Mohammed bin Salman to discuss Iran

US Secretary of State Mike Pompeo has met with Custodian of the Two Holy Mosques, King Salman bin Abdulaziz Al Saud and separately with Crown PrincecMohammed bin Salman to discuss the escalated crisis in the Arabian Gulf.

Pompeo arrived in the Saudi city of Jeddah earlier on Monday in a hastily arranged visit amid mounting tensions between Washington and Tehran as Iran's navy chief warned Iranian forces wouldn't hesitate to shoot down more US surveillance drones from their skies.

Pompeo was greeted upon his arrival in Jeddah by new US Ambassador to Saudi Arabia, John Abizaid and Saudi Foreign Minister Ibrahim al-Assaf.

Before departing, Pompeo said he'd be talking to officials in the Arabian Gulf as well as Asia and Europe as he sets out to build an international coalition against Iran.

While Pompeo said the US is prepared to negotiate with Iran, he also said new US sanctions against Iran are to be announced Monday.
