Iran has multiple major sites associated with its rapidly advancing nuclear program, now the subject of several rounds of negotiations with the United States

Senior Iranian cleric Ahmad Khatami criticized President Trump amid rising tensions as nuclear talks continue in Rome.

Iran and the United States held a fifth round of talks in Rome over Tehran’s rapidly advancing nuclear program.

U.S. special envoy Steve Witkoff will travel to Rome on Friday for a new round of talks with an Iranian delegation over Tehran's nuclear program, a source briefed on the matter said on Thursday.

Iran's Supreme Leader Ayatollah Ali Khamenei slamm ed U.S. demands that Tehran end its uranium enrichment program, stating that he does not believe ongoing nuclear negotiations with the U.S. will yield results. Iran says its nuclear program is for civilian purposes and that its enrichment program is a source of national pride and not negotiable.

Iran’s top diplomat is insisting that Tehran will never stop enriching uranium, further underlining the Islamic Republic’s red line in negotiations with the United States over its rapidly advancing nuclear program.
