US President Donald Trump plans to issue a statement imminently confirming that the US has agreed to a deal with Iran, the Wall Street Journal reports.
Trump told the Journal the deal will either be signed electronically by himself or Vice President JD Vance.
Iran said on Saturday the signing would not be on Sunday though it could happen in the coming days.
Iran's Fars news agency, citing an informed source, said on Sunday Iran had not yet made a final decision on the framework agreement, with reviews of its political, legal and technical aspects under way.
