US President Donald Trump says he will withdraw the US from an Obama-era nuclear agreement with Iran.

Calling it “decaying and rotten”, he said the deal was “an embarrassment” to him “as a citizen”.

Going against advice from European allies, he said he would re-impose economic sanctions that were waived when the deal was signed in 2015.

In response, Iran said it was preparing to restart uranium enrichment, key for making both nuclear energy and weapons.

Iran’s President Hassan Rouhani said: “The US has announced that it doesn’t respect its commitments.

“I have ordered the Atomic Energy Organisation of Iran to be ready for action if needed, so that if necessary we can resume our enrichment on an industrial level without any limitations.”

He said he would “wait a few weeks” to speak to allies and the other signatories to the nuclear deal first.

“If we achieve the deal’s goals in cooperation with other members of the deal, it will remain in place,” he said.

The so-called Joint Comprehensive Plan of Action (JCPOA) curbed Iran’s nuclear activities in return for the lifting of sanctions that had been imposed by the UN, US and EU.

Mr Trump had previously complained that the deal only limited Iran’s nuclear activities for a fixed period; had failed to stop the development of ballistic missiles; and had handed Iran a $100bn (£74bn) windfall that it used “as a slush fund for weapons, terror, and oppression” across the Middle East.

“It is clear to me that we cannot prevent an Iranian nuclear bomb under the decaying and rotten structure of this deal,” Mr Trump said.

“The Iran deal is defective to its core.”

Former President Barack Obama, who signed the deal on behalf of the US three years ago, called Mr Trump’s announcement “misguided”.


European powers try to save agreement after US exit

Meanwhile, European powers say they are committed to the Iran nuclear deal, after President Trump announced the US was withdrawing from the agreement.

The UK, France and Germany urged the US not to obstruct its implementation.

They said they would work with the other signatories to the 2015 deal – Russia and China – which have stressed continuing support for the accord.

In response, Iran said it would restart uranium enrichment, if the agreement could not be salvaged.

In a statement, President Hassan Rouhani said: “I have ordered the foreign ministry to negotiate with the European countries, China and Russia in the coming weeks.

“If we achieve the deal’s goals in co-operation with other members of the deal, it will remain in place.”

There were furious scenes in the Iranian parliament, with members burning an American flag and the speaker reportedly saying Mr Trump lacked “mental capacity”.
