There are about 400 International Atomic Energy Agency (IAEA) inspectors in Iran, and they indicate Iran is complying with the deal. On Friday, the US Treasury Department announced the decision to impose sanctions on 14 individuals and entities responsible for "serious human rights abuses and censorship in Iran".
What are the new sanctions?
Trump said four "critical components" must now be worked into the agreement: immediate inspections at all sites requested by global inspectors, measures to ensure Iran "never even comes close to possessing a nuclear weapon", no policy "expiration date", and no distinction between the Islamic Republic's long-range missile and nuclear weapons programmes regarding the imposition of sanctions. The Treasury Department's action hits 14 Iranian officials and companies and businessmen from Iran, China and Malaysia, freezing any assets they have in the US and banning Americans from doing business with them. The foreign minister added that that the United States president had gone way beyond all behavioral redlines that are acceptable internationally.
That decision came despite the United Nations having certified Iran's compliance with the deal eight times.
How else did Iran react?
Iran says its nuclear program is only for peaceful purposes.
"We carefully manage our relations with the Europeans, and we do not allow the nuclear deal to incorporate other issues." he said.
His number one goal is always to protect the American people, Trump has explained, which is why he ordered a review of the Iranian landmark policy that was forged in 2015 under his predecessor. He, however, agreed to waive major economic sanctions that had been lifted by President Obama as part of the nuclear pact.

There's been no official word as to if standout defensive lineman Christian Wilkins will return for his final season. Earlier this week All-American offensive tackle Mitch Hyatt announced that he would return for his senior year.
The issue was also discussed by French president Emmanuel Macron and Mr Trump in a phone call on Thursday.
Mr Trump was a fierce critic during the 2016 election campaign, calling it the "worse deal ever" and promising to scrap it if he became president.
The President has argued that the deal makes the U.S. look weak but is allegedly willing to waive the sanctions in order to toughen the terms of the agreement.
"If at any time I judge that such an agreement is not within reach, I will withdraw from the deal immediately", he added.
He was prepared to back a modification to the existing deal if it were made permanent, one official said.
"Today, we learned that the president's plan includes bullying our allies into fundamentally altering the terms of a deal that they know is working for our mutual security and have publicly stated they have no interest in amending", it said.
