Iran nuclear deal - live updates: Trump withdraws US from 'disastrous' accord and imposes 'highest level' of sanctions

Donald Trump has said the US is withdrawing from the Iran nuclear deal.

The US president has consistently threatened to leave the 2015 deal because it does not address Tehran's ballistic missile programme or its wars in Syria and Yemen.

European leaders have warned such an outcome would scupper the deal and undo years of work, with France's President Emmanuel Macron speaking with Mr Trump via phone during the morning. Mr Macron said after the announcement that he

A withdrawal will ratchet up tensions in a region divided by interrelated conflicts, including the multi-layered conflict in Syria, where Iran's presence has brought it into conflict with Israel.

It will also impact oil markets due to Iran's role as a major exporter.

In a tweet, Mr Trump said he would make the announcement at 2pm (6pm GMT) on Tuesday.

Iran suggested its economy would not be hurt whatever happened, but its rial was near record lows against the dollar in the free market as Iranians tried to buy hard currency, fearing financial turmoil if Mr Trump leaves the deal.

"One man in one country might create some problems for us for a few months, but we will overcome those problems," Iran's president, Hassan Rouhani, said in remarks broadcast on state TV.

"If we are under sanctions or not, we should stand on our own feet. This is very important for the development of our country."

The Iran deal, negotiated during Barack Obama's administration, eased economic sanctions on Iran in exchange for Tehran limiting its nuclear program.

Mr Trump has called it the "worst deal ever negotiated" and said he wants Britain, France and Germany - which also signed the pact along with Russia and China - to toughen up the terms.

He has until Saturday to decide whether to extend the waivers or withdraw and reintroduce sanctions related to Iran's central bank and Iranian oil exports.

Iran has said it will not renegotiate the accord and threatened to retaliate if the United States pulls out, although it has not said how.
