US Secretary of State John Kerry expected that an agreement on Iran’s nuclear program could be reached in months if the Islamic Republic proves its nuclear program was not being used to build atomic weapons.

An agreement on Iran nuclear program could be met sooner if Iran satisfied certain conditions, Kerry said in an interview with CBS's "60 Minutes" program.
"It's possible to have a deal sooner than that -- depending on how forthcoming -- and clear Iran is prepared to be," Kerry said.

"We need to have a good deal here. And a good deal means that it is absolutely accountable, failsafe in its measures to make certain this is a peaceful program.
"If it is a peaceful program, and we can all see that -- the whole world sees that -- the relationship with Iran can change dramatically for the better and it can change fast," Kerry added.

The United States would not consider lifting sanctions against Iran until it was clear that a "verifiable, accountable, transparent process" was in place, the top US diplomat said.

He said opening up an underground nuclear enrichment facility in the mountains near the city of Qom for international inspection would demonstrate that Iran had no nuclear weapons ambitions.
"They could immediately open up the inspection of the Fordow facility, a secret facility underground in the mountains," Kerry said.

"They could immediately sign the protocols, the additional protocols of the international community regarding inspections."
"They could offer to cease voluntarily to take enrichment about a certain level, because there's no need to have it at a higher level for a peaceful program."

Kerry’s remarks come just two days after US president Barack Obama held a phone call with his Iranian counterpart, Sheikh Hasan Rouhani as the later was heading to New York airport returning to Tehran from the UN General Assembly meetings.

The newly elected president said that the phone call was held at the request of the White House, adding that Obama said that it’s Iran right to enrich uranium.
