Iran and the United States hold direct talks in Switzerland and both sides describe the first day as producing “progress,” despite a tense start. Multiple reports say the initial exchanges are strained, with references to public statements by US President Donald Trump and an Iranian walkout reported by some outlets. Following the strained opening, mediators and participating officials report that technical and diplomatic steps continue and the teams prepare to leave the venue after concluding the first phase of talks. Iran’s foreign ministry officials, including Hossein Amir-Abdollahian Araghchi, are cited as saying there has been major or encouraging progress and that the first round or day of direct negotiations ends successfully. Separately, CNN reports that mediators discuss steps aimed at reducing wider regional tensions, including in Lebanon and around the Strait of Hormuz, while talks proceed. Some outlets also report that technical discussions do not result in new commitments on nuclear issues, indicating that progress may be focused on process rather than concrete nuclear terms. Overall, sources describe a cautious, step-by-step negotiation atmosphere as delegations move to the next stages.
