DUBAI, United Arab Emirates (AP) — Iran and the United States prepared for a fifth round of negotiations over Tehran's rapidly advancing nuclear program Friday in Rome, with enrichment emerging as the key issue. U.S. officials from President Donald Trump down insist Iran cannot continue to enrich uranium at all in any deal that could see sanctions lifted on Tehran's struggling economy. Iran's Foreign Minister Abbas Araghchi early Friday insisted online that no enrichment would mean “we do NOT have a deal.” “Figuring out the path to a deal is not rocket science,” Araghchi wrote on the social platform X.
