The US president argued that the conflict had prevented Tehran from obtaining a nuclear weapon and demonstrated the value of what he described as peace through strength - ultimatums rather than deal-making or compromise." Will a deal be made with Iran that lets them rebuild and create a far greater country than it ever was before?"

he said." Or do I annihilate the Islamic Republic and do it quickly, never giving them a chance to kill and destroy people and countries again?

Do I drive them into hell?" Trump said he believed an Iran deal, which has so far eluded him, would come right after November's elections.

The remarks were indicative of his foreign-policy strategy of coercive diplomacy - threatening overwhelming force while keeping negotiations open. Trump later told reporters that American officials had had a "very productive" three-hour meeting with the Iranian delegation on the sidelines of the general assembly.

Iran state TV confirmed that Foreign Minister Abbas Araghchi had met US Special Envoy to the Middle East Steve Witkoff. Iranian foreign ministry spokesman Esmail Baghaei, quoted by state broadcaster IRNA, later said negotiations took part through a Qatari mediator who communicated Tehran's conditions, including an end to the war on all fronts and to US "acts of aggression".

The BBC asked Witkoff how the meetings had gone as he was leaving the UN building and he responded with a thumbs up. Witkoff later confirmed on X that the talks had been held "through the mediators, who shuttled between the two sides throughout the day"."

They successfully completed a round of discussions that we hope will prove constructive and promising," Witkoff said. " The mediators will continue their work."

In his speech, Trump once again predicted his diplomacy would end Russia's war in Ukraine, which has shown little sign of letting up as the two sides trade tit-for-tat missile and drone strikes deep into each other's territory." We're working very closely with the leaders of Russia and Ukraine, and we will get that one done," he said.

" It's going to happen, I think, more quickly than people understand." US Secretary of State Marco Rubio will meet Russian Foreign Minister Sergei Lavrov in New York on Wednesday, according to the State Department.

Trump also played down fears about AI, vowing that the US would not surrender its lead to China because of alarmism or what he described as a "globalist scheme" to control the technology. The US president argued artificial intelligence should instead be known as "super intelligence"."
