The International Atomic Energy Agency shared the intelligence with 35 nations on Tuesday, but the Iranian representative to the organization says the information was fabricated.
Gregory L. Schulte, the chief U.S. representative to the IAEA, said the evidence shows Iran has a weapons program.
The two spoke separately to reporters after the presentation by the IAEA, one day after the U.N. nuclear watchdog issued a report saying that Iran has stonewalled its attempts to probe allegations that it drew up plans and conducted experiments for a nuclear arms program.
