Hassan Ahmadian, associate professor at the University of Tehran, says he is confident that “nothing” has been agreed between the US and Iran over the nuclear issue, despite Trump’s claim that Iranian authorities will hand over the country’s enriched uranium, The Caspian Post reports, citing Al Jazeera.

“So far, nuclear is subject to discussion and there are mediations going on,” Ahmadian said. “There are ideas mediated by Pakistan that are being sent back and forth, but there is no agreement.”

Ahmadian said Iran’s position was that it respects the Nuclear Non-Proliferation Treaty and insists its enrichment effort is for civilian purposes only.

He added that Tehran’s silence on Trump’s claims was not unexpected, given that Friday is a day of rest in Iran, and that he expected the leadership to soon comment with “its own narrative”.
