Opposition to a reported U.S.-Iran peace agreement is intensifying inside Iran as hardline politicians openly challenge the negotiations and accuse officials of crossing the country's political red lines. Iranian lawmakers including Kamran Ghazanfari and Seyed Mahmoud Nabavian have criticized the emerging framework, warning that any deal reached under U.S. pressure could lack legitimacy. The backlash comes as reports of an imminent agreement fuel debate across Iran's political establishment, with hardliners questioning whether the negotiations have the backing of Mojtaba Khamenei. The dispute highlights growing divisions within Tehran as diplomatic efforts with the United States move forward.
