MOSCOW (Reuters) - Iran's foreign minister Mohammad Javad Zarif said on Saturday that demands by U.S President Donald Trump to change Tehran's nuclear deal with world powers were unacceptable. Trump has said that unless European allies fix the "terrible flaws" in the Iran nuclear deal by May 12, he will refuse to extend U.S. sanctions relief for oil-producing Iran.
