US intelligence indicates Iran is in “advanced stages” of plotting attacks on US government personnel in the Middle East and certain other countries, the US director of national intelligence said Friday.

In a memo to Secretary of State Marco Rubio, Jay Clayton said Iran had “substantially increased” its “lethal” plotting against American diplomats and other government personnel.

Also on Friday, the State Department updated its travel advisories for 13 Middle Eastern countries to reflect the perceived heightened Iranian threat to US officials. 

Concerns about attacks on US government personnel prompted the State Department on Friday to order the departure of non-emergency personnel and dependents from Saudi Arabia.  Ongoing missile and drone attacks on Saudi Arabia by Yemen’s Houthi militia, an ally of Iran, also contributed to that move.

The US-Iran war currently is at low boil.

But negotiations to end the conflict have broken down and there are serious concerns about a major escalation in hostilities in coming days and weeks. 

Recent military deployments have made clear President Donald Trump is weighing renewed heavy bombing of Iran.

Iran repeatedly has indicated that it could go beyond its targeting of US military bases in the region with missiles and drones and systematically strike oil industry facilities and critical infrastructure in the Gulf Arab countries.

The Iranian regime’s Islamic Revolutionary Guard Corps (IRGC) for decades has seeded the Gulf Arab monarchies and some other countries in the Middle East with sleeper operatives. 

US intelligence now has elevated concerns about IRGC terrorist attacks on US government personnel.

This service long assessed that the IRGC probably would not target American or other Western civilians in terrorist attacks.

That remains our assessment.  Yet nothing can be taken for granted given the extent to which the Iran-US war has overturned regional security norms.
