A senior Iranian source told ​Reuters on Sunday ‌that Tehran has not agreed to hand ​over its highly ​enriched uranium stockpile.

The ⁠source said Iran’s ​nuclear issue was not ​part of the preliminary agreement with the United States.

“The ​nuclear issue will ​be addressed in negotiations for ‌a ⁠final agreement and are therefore not part of the ​current deal. ​There ⁠has been no agreement over ​Iran’s highly enriched ​uranium ⁠stockpile to be shipped out of ⁠the ​country,” said ​the source.

Meanwhile, Fars News reported on Sunday that a potential memorandum of understanding between Iran and the United States would temporarily lift sanctions on Iran’s oil, gas, petrochemicals and related products during the negotiation period.

The report said the measure would allow Iran to sell those products freely while talks were underway.

If Iran’s supreme national security council approves the memorandum of understanding, it will then be sent to Supreme Leader Mojtaba Khamenei for final approval, according to Reuters, citing a senior Iranian source.
