Hello and welcome to NewsHour from the BBC World Service. We're coming to you live from London. My name's Paul Henley.

There are conflicting claims today about the state of Iran's nuclear program following recent Israeli attacks

and the bombing missions launched by the US a week ago on Iranian nuclear facilities.

The chief of the UN's nuclear watchdog, Rafael Grossi, has said Iran has the capability to

start enriching uranium again in a matter of months for a possible bomb.

In an interview with the BBC's US partner, CBS News, he said there'd been severe damage to Iran's nuclear sites, but not total damage.

Iran had a very vast, ambitious program, and part of it may still be there.

And if not, there is also the self-evident truth that the knowledge is there, the industrial capacity is there.

Iran is a very sophisticated country in terms of nuclear technology, as is obvious.

Military operations are not, you are not going to solve this in a definitive way militarily.

Well, a report in today's Washington Post also claims U.S.

intelligence intercepted communication between senior Iranian officials after the U.S.

attacks. It said the discussion was about the strikes having been less devastating than

expected. The paper cites four anonymous American insiders familiar with classified US intelligence.

In public, at least, President Trump is of a different opinion.

He says the US operation completely and totally obliterated Iran's nuclear program.

And the CIA in Washington says the program will take years to rebuild.

Iran's deputy foreign minister has been telling the BBC

that his country will not enter into talks on its nuclear program

unless America guarantees not to bomb it again during negotiations.
