US Secretary of State Rex Tillerson has accused Iran of "alarming ongoing provocations" aimed at destabilising the Middle East and undermining America's interests in the region, a media report said.
Tillerson said the review would not only look at Iran's compliance with the 2015 nuclear deal but also its behaviour in the region which he said undermined USA interests in Syria, Iraq, Yemen and Lebanon.
However, in a letter sent late Tuesday to House Speaker Paul Ryan, US Secretary of State Rex Tillerson said the administration has undertaken a full review of the agreement, known as the Joint Comprehensive Plan of Action, AP reported.
The state department is obliged to inform Congress every 90 days about Iran's compliance with the deal.
"This deal represents the same failed approach of the past that brought us to the current imminent threat we face from North Korea", Tillerson continued.
As with North Korea, Tillerson said, the Trump administration is unwilling to be patient with Iran, ticking through a list of countries where he said Iran supports terrorism and violence.
Trump, in a news conference with the visiting Italian premier, didn't telegraph whether he would ultimately decide to keep the U.S.in the deal or not, though he called it "terrible agreement" that was poorly negotiated.

Rouhani has on several occasions called for massive turnout in the elections slated for May 19. He has emphasised his concern for the poor, and is seen as a close ally of the supreme leader.
While disparaging the nuclear deal and accusing Iran of fomenting violence and terrorism throughout the Middle East, Trump has avoided committing to abandoning the agreement, a move that would be staunchly opposed by USA businesses and European allies.
Asked at a news briefing if Trump had chose to pull out of the 2015 deal, White House spokesman Sean Spicer said the 90-day inter-agency review, announced on Tuesday, would make recommendations on the path forward.
Instead, they see the administration's harsh words as both a warning to rogue regimes such as North Korea and an effort to create political cover for sticking with the deal after President Donald Trump's campaign criticism of the pact as a "horrible deal". "We buy them off for a short period of time, and then someone has to deal with it later". It was the first such notification under U.S. President Donald Trump. He said in July 2015 that "Iran is going to receive a sure path to nuclear weapons".
Weeks after he said he was moving on after a failed attempt in Congress to replace the Affordable Care Act, Trump said "there's no give-up" and predicted a proposed GOP overhaul of Obama's health care law was gaining popularity.
"I think the Iran deal is the dumbest deal you could imagine". The agreement allowed rich and poor countries to set their own goals to reduce carbon dioxide and went into effect last November, after the U.S., China and other countries ratified it.
Trump has followed through with a pledge to pull the US out of the Trans-Pacific Partnership, a sweeping free trade deal president Barack Obama negotiated.
