A rare public dispute has erupted inside Iran's Assembly of Experts after a majority of its members issued a statement on the US-Iran memorandum of understanding, prompting an extraordinary public rebuke from the body's own leadership within hours.

Axar.az informs, citing Iran International, the exchange has exposed signs of growing infighting at the highest levels of the Islamic Republic.

The normally quiet body, responsible for appointing and theoretically overseeing the supreme leader, has become the latest arena for disagreement over negotiations with Washington, the reopening of the Strait of Hormuz and the limits of compromise with the United States.

The controversy began after more than 60 of the Assembly's 84 members published a statement on Saturday that ventured far beyond the body's customary role, laying out detailed positions on the memorandum, the Strait of Hormuz, Lebanon, nuclear negotiations and retaliation against the United States and Israel.

The signatories thanked Iranian negotiators but warned them to learn from what they called the failures of previous talks, adding that observing Supreme Leader Mojtaba Khamenei's red lines was a religious obligation and that violating them was "not permissible under any circumstances."
