Iran is reviewing "concrete proposals" from mediators on the future of its nuclear program amid talks with the United States in Doha, Qatar, The New York Times reported on Thursday.
The report cited five officials, including an American and two Iranians, briefed on the talks, noting that the revelation suggests some progress in negotiations with the US.
The officials, speaking on condition of anonymity, did not elaborate on the specifics of the proposals.
The NYT reached out to the Iranian Foreign Ministry for comment, which has not yet responded.
Iran's leaders shift stance to support nuclear weapons
On Wednesday, the NYT reported that a growing number of Iranian clerics and officials are pressing their leaders to reverse their pledge not to pursue nuclear weapons.
Former Iranian supreme leader Ayatollah Ali Khamenei issued a fatwa forbidding the development and use of nuclear weapons, though US and Israeli intelligence agencies have reported signs that Iran is enriching uranium beyond peaceful levels.
Iran sent the US a nuclear proposal via Qatar later on Thursday, which it said it would discuss only after Washington meets its seven demands, a senior Iranian official told Reuters, adding that Washington is reviewing the proposal.
