Trump says he is ‘not happy’ with the Iran nuclear talks but indicates he’ll give them more time

President Trump has said he is not happy with Iran in the wake of the latest talks on its nuclear programme, but said he had not yet decided whether to attack the country.

“I’m not happy with the fact that they’re not willing to give us what we have to have. So I’m not thrilled,” Trump said in his first comments on negotiations in Geneva that broke up on Thursday without a deal.

The US president stressed that he did not want to use military force against Iran, but said sometimes “you have to”.

Concern over the prospect of US strikes against Iran led a number of countries to issue warnings to their citizens in the region on Friday.

The UK temporarily withdrew staff from its embassy in Tehran and updated its travel guidance to advise against “all but essential travel” to Israel.

Countries including China, India and Canada urged their citizens to leave Iran as soon as possible due to the prospect of hostilities. Germany advised “urgently” against travel to Israel while France reiterated its advice not to do so.

Meanwhile, the US urged its citizens in Iran to leave “immediately”. Its embassy in Israel also told some non-emergency staff and their families they could leave the country, advising that they may wish to do so “while commercial flights are available”.

Trump has threatened military action against Tehran if it does not reach a deal about its nuclear ambitions.

He has ordered the largest US military build-up in the Middle East since the US-led invasion of Iraq in 2003, while Iran has vowed to respond to an attack with force.

Washington and its allies suspect Iran is moving towards developing a nuclear weapon, which Tehran has always denied. It claims its programme is intended for peaceful, civilian purposes despite having enriched uranium up to near weapons-grade level.

The president told reporters on Friday: “I say no enrichment… I think it’s uncivil.”

It came as Oman’s Foreign Minister Badr Albusaidi, who was mediating the talks, said Tehran had agreed never to stockpile enriched uranium, making “the enrichment argument less relevant”.

“If you cannot stockpile material that is enriched then there is no way you can actually create a bomb,” Albusaidi told CBS News.
