A quick update to my previous post: Bloomberg reports:
The threat is “generic” and likely related to U.S. moves to sanction Iran over its nuclear weapons program, according to Anthony Davis, a Bangkok-based analyst at IHS Jane’s.
The U.S. is “looking at pro-Iranian groups that might possibly react to what may very well go down in the Straits of Hormuz and possibly beyond,” Davis said. “It seems unlikely that terrorist attacks would be launched before the situation in the Middle East has escalated significantly.”
Tensions over the ratcheting up of sanctions led Iranian Vice President Mohammad Reza Rahimi to threaten on Dec. 27 that Iran may block the Strait of Hormuz, the transit for about a fifth of the world’s oil, if the European Union bans exports from the Islamic Republic.
