The Pentagon has secret plans for a “remote control” blitz on Iran if it does not comply with demands to curb its nuclear programme.
Dozens of targets, including nuclear complexes deep underground, would be destroyed by bunker-busting cruise missiles.
And assassinations of key personnel working on the installations are planned using Hellfire rockets fired from unmanned Predator planes.
The Mirror learned details of the plans yesterday as Foreign Secretary Jack Straw dismissed reports that Iran will be attacked with nuclear weapons by the US.
He said: “The idea of a nuclear strike is completely nuts.”
A British intelligence source with close links to US intelligence also ruled it out. He told the Mirror: “The nuclear option will have been considered among many other options for a strike.
