U.S. President Donald Trump warned Iran on Tuesday to adhere to the terms of the nuclear deal with world powers or "there will be big, big problems" for Tehran.
Speaking at a rally in Youngstown, Ohio, and quoted by Reuters, Trump said Iran has been emboldened by the nuclear deal, but added "that won't take place much longer."
He did not provide specifics.
Trump's administration just last week confirmed that Iran is adhering to the nuclear agreement it signed with world powers in 2015, marking the second time since Trump took office that it had done so.
However, Trump and other officials in the administration have stressed that the President has reservations about the deal.
During the presidential election campaign, Trump was highly critical of the Iran nuclear deal, saying it was “disastrous” and pledging to annul it.
After he was sworn in as president, Trump described the nuclear deal as “the worst deal I’ve ever seen negotiated” and accused the Islamic Republic of “disrespecting” the United States because of the deal.
Iranian officials have downplayed Trump’s criticism of the nuclear deal, saying he could not annul the deal even if he wishes to do so.
Iran’s Foreign Minister, Mohammad Javad Zarif, took things even further, saying in March his country is prepared to resume its nuclear activities if the United States continues its “lack of commitment” to the nuclear deal.
While lifting nuclear-linked sanctions, the United States maintains sanctions related to Iran's ballistic missile program, human rights record and its support for international terrorism.
Earlier on Tuesday, the House of Representatives approved new legislation that imposes sanctions on people involved in Iran's ballistic missile program applies terrorism sanctions to the country's Revolutionary Guards.
