Nadergholi Ebrahimi has asked Supreme Leader Khamenei to rethink Iran's nuclear policy if negotiations with the U.S. collapse.

The latest round of high stakes nuclear talks between Iran and the US have ended, with Tehran calling them difficult but with both sides agreeing to further negotiations.

Iran condemned the United States for imposing new sanctions on its nationals and a company, calling the move unjust and contradictory as both sides pursue indirect negotiations over Tehran’s nuclear program and the anti-Iran sanctions.
