In an interview with Fox News, Grossi said that Iranian officials moved the enriched uranium to another location as a "precautionary measure" prior to the U.S. strikes.
When asked about allegations that the stockpile had been moved to an old facility near Isfahan, Grossi responded:
"We are the IAEA, we do not speculate. We have no information about the current location of this material."
Grossi added:
"My job is to try to determine where this material is, because Iran is obliged to declare and account for all its nuclear material — and that continues to be my responsibility."
