Iran has “sort of” agreed to a deal with the US on its nuclear programme, Donald Trump said.

Speaking in Doha, Qatar, the US president said Washington was getting close to an agreement with Tehran and emphasised that he would not allow the regime to build a nuclear weapon. 

Earlier, an adviser to Iran’s supreme leader told NBC News that Tehran is willing to make concessions on its nuclear programme in exchange for the lifting of sanctions.

These would include committing to not making a nuclear weapon and getting rid of stockpiles of highly-enriched uranium, which can be weaponised.

Mr Trump is on the third day of a four day visit to the Middle East that has included lucrative visits to Saudi Arabia and Qatar.

He will shortly deliver a speech to US troops at Al Udeid Air Base in Qatar, before heading to the UAE later today.

Mr Trump will meet Mohammed bin Zayed Al Nahyan, the UAE’s president, to discuss investment opportunities largely in the sectors artificial intelligence, energy and manufacturing.

In March, the Gulf state announced a $1.4 trillion investment plan with the US for the next decade. Mr Trump is also expected to lift Biden-era export restrictions on advanced technologies, as the UAE is seeking US-made microchips and AI systems to become a global AI leader by 2031.
