BBC NEWS — Diplomatic sources have told the BBC that as a fallback plan, senior officials at Central Command in Florida have already selected their target sets inside Iran.
That list includes Iran’s uranium enrichment plant at Natanz. Facilities at Isfahan, Arak and Bushehr are also on the target list, the sources say.
BBC security correspondent Frank Gardner says the trigger for such an attack reportedly includes any confirmation that Iran was developing a nuclear weapon – which it denies.
The Natanz plant is buried under concrete, metal and earth
Alternatively, our correspondent adds, a high-casualty attack on US forces in neighbouring Iraq could also trigger a bombing campaign if it were traced directly back to Tehran.
Long range B2 stealth bombers would drop so-called “bunker-busting” bombs in an effort to penetrate the Natanz site, which is buried some 25m (27 yards) underground.
