According to a source cited by Al Arabiya, Washington and Tehran are expected to come to a preliminary deal about lowering uranium enrichment levels. The channel reports that if a more extensive agreement is achieved, the US is ready to release between $6 billion and $9 billion in Iranian funds.

Sources informed Al Arabiya that the US has permitted Iran to enrich uranium to 3.67%, and Tehran has accepted Washington’s conditions. The United States is likewise insisting on a decrease in the amount of Iran’s uranium that has been enriched to 60%. The parties are willing to include a third country in conversations regarding this issue.
Sources note that Washington and Tehran are also ready to negotiate the return of IAEA inspectors to Iran. The total of International Atomic Energy Agency staff that may come back to Iran is still unclear.
Sources from Al Arabiya revealed that a “serious negotiation process” has commenced between the US and Iran, with Qatar and Pakistan acting as mediators. A broader, potential agreement could entail the release of certain Iranian assets, the reopening of the Strait of Hormuz, and the removal of the maritime blockade on Iran.
