In his address to the UN General Assembly on Tuesday, Trump said he faced a “big decision” – either negotiate a deal that would allow Iranians to rebuild their country, or “annihilate the Islamic Republic and do it quickly”.

Pezeshkian said the threat was “a sign of a bullying mentality”.

“[Trump] must know that the resistance of the Iranian people will only increase in the face of sanctions, increased pressure, increased bullying. We will never bow our head or bend the knee,” he said.

But he added: “We are ready for dialogue and diplomacy and negotiations without accepting the language of force.”

Pezeshkian made clear that the US blockade would have to end as part of any deal.

“It cannot be the case that everyone benefits from the Strait of Hormuz while we are denied access to shipping through this waterway,” he said.

He also reiterated that Iran would not give up its right to have a civilian nuclear programme and that it would not seek to develop nuclear weapons.

“We say it clearly: no nuclear weapons and no limitations on peaceful nuclear technology.”

Trump argued in his speech that the war had prevented Iran from obtaining a nuclear bomb and demanded that its leaders “relinquish their nuclear ambitions”.

On Tuesday, Iranian Foreign Minister Abbas Araghchi and US envoy Steve Witkoff held indirect talks brokered by Qatari mediators on the sidelines of the UN General Assembly in New York.

Witkoff said he hoped the discussions – the first since June – would “prove constructive and promising”, adding that the mediators would continue their work.

But Iran’s foreign ministry spokesman Esmail Baqai said the talks were “not anything new” and that Araghchi had maintained Iran’s conditions, including the end of the US blockade and the release of frozen Iranian assets.
