TEHRAN, Iran (AP) — Iran says it won't accept any changes to its 2015 nuclear deal with world powers after 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 Saturday, the Foreign Ministry says 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."

On Friday Trump extended the waivers of key economic sanctions that were lifted under the agreement limiting Iran's nuclear program. But he said he would work with European allies to remove so-called "sunset clauses" that allow Iran to gradually resume advanced nuclear activities in the next decade.
