UN Nuclear Watchdog Chief: ‘Night and Day’ Difference Between Iran’s Nuclear Capabilities Before and After US Strikes
25th June 2025
“I think the Iranian nuclear program has been set back significantly, significantly,” International Atomic Energy Agency (IAEA) director general Rafael Grossi said in a Fox News interview. He noted that “it is clear that there is one Iran—before June 13, nuclear Iran—and one now,” describing the difference as “night and day.”
Just before the Tuesday afternoon interview, the IAEA revealed that it detected “extensive damage at several nuclear sites in Iran, including its uranium conversion and enrichment facilities.” That damage caused a radioactive release, according to the organization.
“Our assessment is that there has been some localized radioactive as well as chemical release inside the affected facilities that contained nuclear material—mainly uranium enriched to varying degrees—but there has been no report of increased off-site radiation levels,” Grossi said in the IAEA statement. The organization observed “two impact holes from the U.S. strikes” at Iran’s Natanz enrichment site above “the underground halls that had been used for enrichment as well as for storage,” according to the statement, in which Grossi also said he saw “extensive damage at several nuclear sites in Iran, including its uranium conversion and enrichment facilities.”
