Iran’s foreign minister Abbas Araghchi said Tehran would be ready to submit its plan for a nuclear agreement to the United States in the coming days, after president Donald Trump threatened military action.

‘The next step for me is to present draft of possible deal to my counterparts in the US. I believe that in the next two, three days, that would be ready, and after final confirmation by my superiors, that would be handed over to Steve Witkoff,’ Araghchi said in an interview published online on Friday with the Morning Joe show on US TV network MSNBC.

Trump said on Thursday that Iran had at most 15 days to make a deal on concerns starting with its nuclear programme, suggesting the United States would attack if it did not.

‘Well, I have to say that first of all, there is no ultimatum. We only talk with each other how we can have a fast deal. And a fast deal is something that both sides are interested about,’ Araghchi said.

Iran on Thursday warned that US bases, facilities and assets would be ‘legitimate targets’ if the United States follows through on its military threats and attacks.

Amir Saeid Iravani, the Iranian ambassador to the United Nations, made the remarks in a letter to UN secretary general Antonio Guterres and the president of the Security Council that was seen by AFP.

Trump has deployed warships, fighter jets and other military hardware to the Middle East as he seeks to block Iran from building a nuclear bomb, something Tehran says it is not pursuing.

The letter cited a social media post by Trump on Wednesday, where he said the United States may need to use UK military bases, including one on an Indian Ocean island, ‘should Iran decide not to make a deal.’

‘Such a belligerent statement by the president of the United States…signals a real risk of military aggression, the consequences of which would be catastrophic for the region and would constitute a grave threat to international peace and security,’ Iravani wrote in the letter.

He called for the Security Council — the UN’s top decision-making body where Washington has veto power — to ‘ensure that the United States immediately ceases its unlawful threats of the use of force.’

The letter said Iran remains committed ‘to diplomatic solutions’ and ‘on a reciprocal basis, addressing ambiguities regarding its peaceful nuclear programme.’

But Iravani warned if Iran faced military aggression, ‘all bases, facilities, and assets of the hostile force in the region would constitute legitimate targets in the context of Iran’s defensive response.’

Trump has repeatedly threatened military action against Iran, citing a deadly crackdown on anti-government protesters last month then more recently over its nuclear program.

On Thursday, Trump said that Iran had at most 15 days to make a deal and again suggested that the United States would attack if failed to do so.

His comments followed talks on Tuesday in Geneva between US envoys Steve Witkoff and the president’s son-in-law Jared Kushner, who met indirectly with Iran’s top diplomat, who said that there was progress.

A previous attempt at negotiations collapsed when Israel launched surprise strikes on Iran last June, beginning a 12-day war that Washington briefly joined to bomb Iranian nuclear sites.
