The New York Times, citing five officials familiar with the negotiations:
Iran is currently considering a set of practical proposals that may determine the future of its nuclear program.
Tehran's willingness to return to discussing the nuclear issue after weeks of refusing to back down indicates that the Qatari mediation has made some progress.
Officials described what was being discussed as "concrete proposals," but declined to disclose their details.
These developments may open the door to a diplomatic breakthrough to end the war between the US and Iran.
