TEHRAN, IRAN—Iran said Saturday it won’t accept any changes to its 2015 nuclear deal with world powers after U.S. President Donald Trump vowed to pull out of the accord in a few months if European allies did not fix its “terrible flaws.”

In a statement carried by the state-run IRNA news agency, the Foreign Ministry said Iran “will not accept any change in the deal, neither now nor in future,” adding that it will “not take any action beyond its commitments.”

It also said Iran would not allow the deal to be linked to other issues, after Trump suggested that the sanctions relief under the deal be tied to Iran limiting its long-range ballistic missile program. Iran “will not accept any amendments in this agreement, be it now or in the future, and it will not allow any other issues to be linked to the JCPOA,” the foreign ministry said in a statement, using the 2015 deal’s technical name. It also said Iran would not allow the deal to be linked to other issues, after Mr. Trump suggested that the sanctions relief under the deal be tied to Iran limiting its long-range ballistic missile program. Iran argues that continued US sanctions on non-nuclear areas such as human rights and missile testing have effectively barred Iran from gaining many of the financial benefits expected from the deal. “The Trump regime’s hostile action (against Larijani)... crossed all red lines of conduct in the international community and is a violation of international law and will surely be answered by a serious reaction of the Islamic Republic,” Iran’s Foreign Ministry said in a statement carried by state media.
U.S. President Donald Trump says he is extending sanctions relief for Iran one last time so Europe and the U.S. can fix the nuclear deal's "terrible flaws".
