While Iran says it has responded to the latest US proposal to end the conflict, senior officials have made defiant statements regarding the prospect of negotiations, CNN reports.
"We will never bow our heads to the enemy, and if talk of dialogue or negotiations arises, it does not mean surrender or withdrawal," Iranian President Masoud Pezeshkian said in a post on X.
"On the contrary, the goal is to protect the rights of the Iranian nation and defend national interests with resolute force," he added.
"Time is working against the Americans. It is in their interest not to act foolishly and not sink deeper into the quagmire they have fallen into," tweeted Ebrahim Rezaie, a member of the security committee in the Iranian parliament.
"The best option is to surrender and make concessions. You have to adapt to the new regional order," Rezaie said.
The hardline deputy speaker of parliament, Ali Niksad, said the United States had chosen to test "its fate against a great and powerful Iran, and now you must accept the consequences."
Iranian state media have provided few details about the response sent through a Pakistani intermediary, other than saying that "according to the proposed framework, negotiations at this stage will focus on the issue of ending the war in the region."
