The Islamic Republic is "reviewing" the views of the American side, CNBC cited Iran Foreign Ministry spokesperson Esmaeil Baghaei as saying in a report from the state-run Nour News on Thursday.

Meanwhile, Iran's Supreme Leader Ayatollah Mojtaba Khamenei ordered enriched uranium to remain in the Islamic Republic, Reuters reported Thursday, citing two senior sources from the country.

"We will get it. We don't need it, we don't want it. We'll probably destroy it after we get it, but we're not going to let them have it," Reuters cited Trump as telling reporters at the White House on Thursday.
