Iran is considering new proposals from mediators about the future of its nuclear program that could mark a breakthrough in stalled negotiations aimed at ending the war with the United States, according to Now, citing five officials familiar with the talks. Tehran's renewed willingness to participate in nuclear negotiations after weeks of resistance suggests Qatar-led mediation efforts to prevent a return to full-scale hostilities may be gaining traction. Officials described the terms being considered as "concrete proposals," but did not provide further details.
