US picks Iran military targets

London: The US has drawn up plans for air strikes on Iran that extend beyond nuclear sites and include most of the country's military structure, it has been revealed.

It is thought that any such attack, if ordered, would target Iranian air bases, naval bases, missile facilities and command and control centres.

The US insists it is not planning to attack and is trying to persuade Tehran to stop uranium enrichment. But diplomatic sources have said that, as a fallback, senior officials at Central Command in Florida have already selected their targets.

The list includes Iran's uranium enrichment plant at Natanz. Facilities at Isfahan, Arak and Bushehr are also on the target list, sources told the BBC.

The trigger for such an attack reportedly includes any confirmation that Iran was developing a nuclear weapon - which it denies.

Details of the US plans emerged as the UN nuclear watchdog warned that Iran could be just six months from acquiring the ability to enrich industrial-scale uranium - a key step in building a nuclear bomb.

Mohammad Al Baradei, head of the International Atomic Energy Agency, said he expected Tehran would ignore a UN deadline to suspend enrichment work by today.

Attempting to knock out Iran's current small-scale nuclear facilities through military action would be futile, he said. "I know for sure that this would be catastrophic, counter-productive," he said.
