Despite the US exit, Britain and Iran on Sunday expressed their commitment to ensuring that the accord is upheld, according to a statement released by British Prime Minister Theresa May's office.
Iran's foreign minister will travel to Moscow on May 14 and meet his Russian counterpart, Russia's RIA news agency said, citing a Russian foreign ministry official.
When asked if tensions between Israel and Iran have escalated because the US withdrew from the nuclear deal, Pompeo said, "That's ludicrous to suggest that Iran feels less constrained when during the JCPOA that have now fired missiles into an airport where Americans travel each day in Riyadh".
The White House said Trump had spoken with French President Emmanuel Macron on Saturday and "reiterated the need for a comprehensive deal that addresses all aspects of Iran's destabilizing activity in the Middle East".
World powers agreed to lift some of the economic sanctions imposed on Iran in return for the latter agreeing to rein in its nuclear program.
Iranian Foreign Minister Javad Zarif said he would try and save the 2015 Iran Nuclear deal through negotiations with the European nations who were co-signatories to the deal.
And the Number 10 spokesman added: "The Prime Minister raised the potential impact of USA sanctions on those firms which are now conducting business in Iran".
He continued, "To suggest that somehow the withdrawal from the JCPOA is driving the Iranian conduct that has taken place during the JCPOA in Yemen, the rise in Hezbollah, all of those things took place during the JCPOA". They have also condemned the attacks on Iranian military facilities in Syria that were carried out by Israel earlier this week.
Babüroğlu proceeded to say that the tensions between Israel, the United States and Iran would affect Turkey, which maintains close ties with Tehran on a wide range of matters in the regions.
During the phone call Mrs May also congratulated the United States president on the safe return of three Americans who had been held in prison in North Korea.
Bolton said Europe was still digesting Trump's May 8 move.
"The PM said the United Kingdom would continue to work with the U.S. to keep up the pressure on North Korea to denuclearise".
Trump may also have been emboldened to act more punitively against Iran because it lacks North Korea's powerful intermediaries. The U.S. exit, together with its threaten to sanction companies economically involved with Tehran, has sparked outrage in Europe.
Trump's tough talk now on sanctions is at odds with what he told France's Emmanuel Macon and May just six months ago as he moved toward yanking the US out of the deal.
"Do we accept that the United States is the economic gendarme of the planet? The answer is no.", he said. France has come down heavily on the decision, with French Finance Minister Bruno Le Maire saying that Europe can not afford to follow the whims of the United States when it comes to protecting its economic and diplomatic interests, according to BBC. "The answer is no".
"If the remaining five countries in the deal live up to their commitments and guarantee Iran's interests, the agreement will survive", he said during a meeting with visiting Sri Lanka President Maithripala Sirisena.
On Friday the Kremlin said Russian President Vladimir Putin had spoken with Germany's Angela Merkel and Turkey's Recep Tayyip Erdogan in a bid to keep the Iran nuclear deal alive.
