By close to day's end on Friday, both sides appear in agreement that no deal has been reached. First, fresh reporting after a two-hour White House situation room meeting from the NY Times:

President Trump's meeting in the Situation Room lasted about two hours, but the president did not reach a decision on any new deal with Iran, according to a senior administration official who spoke on condition of anonymity to speak about internal deliberations.

The administration believes it is close to an agreement but there are still certain matters being debated including the unfreezing of funds for the Iranians, the official said.

And from the Iranian side, the last afternoon official message was as follows (Reuters, state sources):

A senior Iranian source tells Reuters that a political understanding has been reached between Iran and the US, though it has not yet been finalized.

Trump: Iran's Uranium will be unearthed by the United States; Fars: Trump's claims "mix of truth and lies"

These Truth Social messages are starting to appear uncannily similar to ones already issued weeks ago. But this seems more confirmation that there is no MOU which has been 'finalized' - but that some key things have been agreed to.

Iran "must agree" to never have a nuclear weapon
