Iran calls Vance letter a 'good sign' for nuclear talks

Iran's top security official, Mohsen Rezaei, said the US has "completely shifted tone" in a letter from Vice President JD Vance, marking the first official Iranian reaction to the diplomatic overture. The letter, delivered via Qatari mediators, proposes direct talks under Vance's leadership, with Iran's nuclear programme included from the start. Rezaei called the shift a "good sign," while Foreign Minister Abbas Araghchi described Washington's attempt as a "positive step." A meeting could occur within a week in Doha or Istanbul, though Supreme Leader Mojtaba Khamenei warned of a "geographically unrestricted" military response to any US or Israeli missteps. President Donald Trump maintains Tehran wants negotiations, claiming the conflict will end "very soon."
