據伊朗伊斯蘭共和國通訊社（IRNA）：伊朗方面表示，此次瑞士對話的結果將明確華盛頓是否真的有意願進入第二階段談判。

據伊朗伊斯蘭共和國廣播電視臺（IRIB）：在首輪80分鐘會談期間，各方未就伊朗核計劃進行任何談判。

CNN reported that after Iran announced on Saturday it would close the Strait of Hormuz, the Islamic Revolutionary Guard Corps' naval unit warned vessels not to approach the waterway. A state broadcaster reporter said the IRGC issued radio warnings and directly contacted ships, saying vessels attempting to transit could encounter sea mines or be targeted by Iranian naval forces. The reporter added vessel traffic in the Persian Gulf had fallen further compared with several hours earlier.
