Iran’s Tasnim news agency on Tuesday reported that Iranian parliament speaker Mohammad Bagher Ghalibaf discussed in Qatar how Iran could obtain $12 billion as a first step in an agreement between Tehran and the United States.

The Associated Press also reported that the United States and Iran reached an understanding on Tuesday over the issue of Iran’s frozen funds. The agency said Qatari mediation had succeeded in securing a common understanding between the two sides on the matter.

According to the report, both parties are expected to announce an agreement on the funds later on Wednesday.

A source close to the Iranian negotiating team told Tasnim that, under the understandings, around $24 billion in Iranian funds would be released. Iran is insisting that half of the amount be made available at the time the memorandum of understanding is announced, with the remaining funds to be transferred within 60 days.

The first phase of the memorandum of understanding also includes the withdrawal of US forces and all military reinforcements deployed to the Middle East before, during and after the war.
