Senior Iranian negotiator Mohammad Reza Kalbaf said the United States must be careful in its statements and that Iran’s armed forces are ready to act. A source cited by Tasnim reported that the Iranian delegation walked out of negotiations in protest of remarks made by former President Donald Trump. An Iranian team member told state media that talks on other issues will not proceed until the war in Lebanon ends. The foreign ministry said Sunday’s negotiations focused on ending the war, easing sanctions and releasing Iran’s frozen assets, with a draft on oil sanction exemptions expected soon.
