Revolutionary Guards spokesman Hossein Mohebi said on Tuesday that Iran had hardened its conditions for ending the war with the United States following the collapse of a June deal, adding Washington now had "no choice" but to accept its demands.

Iran had previously agreed with the United States to a memorandum of understanding laying out a pathway to a permanent settlement of the conflict, only for the deal to later unravel as each side accused the other of violating it.
