Iranian officials slammed President Trump on Saturday over his decision to pull out of its 2015 nuclear deal if all parties in involved in the agreement refuse to renegotiate the terms.

In a statement to state-run media, Tehran said it “will not accept any change in the deal, neither now or in [the] future.” Iran’s foreign minister, Mohammad Javad Zarif, tweeted a day earlier that the U.S. “must bring itself into full compliance” with the nuclear agreement.
