Iran’s supreme leader has criticized an initial proposal from the United States in negotiations over Tehran’s rapidly advancing nuclear program.

Iran's Supreme Leader Ayatollah Ali Khamenei said that abandoning uranium enrichment was "100%" against the country's interests.

Iran’s Supreme Leader Ayatollah Ali Khamenei has publicly rejected a new U.S. nuclear deal proposal, vowing to continue uranium enrichment despite mounting international pressure and a new IAEA report warning that Iran’s stockpile of near-weapons-grade uranium has surged by 50% in just three months.
