Donald Trump has slammed Iran and said it has committed multiple violations of a 2015 deal aimed at stopping the country develop a nuclear bomb.

He gave the US Congress 60 days to decide whether to reimpose economic sanctions on Tehran that had been lifted when the agreement was signed two years ago.

If not, he said, he would pull the US out of the deal.

“Today I am announcing our strategy along with several major steps we’re taking to confront the Iranian regime’s hostile actions and to ensure that Iran never — and I mean never — acquires a nuclear weapon,” Trump said.

The EU’s foreign policy chief, Federica Mogherini, contradicted Trump saying it was not up to any one country to cancel the agreement.

She said the international community cannot afford to dismantle an accord that is “working and delivering”.

Other signatories of the deal, France, Germany and the UK, released a statement saying preserving it was in their joint national interest.
