Nuclear watchdog agency's general director says Iran's capabilities suffered "severe damage"

Iran's nuclear capabilities suffered "severe damage" in last week's U.S. airstrikes but not "total damage," said the man in charge of the world's global nuclear watchdog, the International Atomic Energy Agency. "One cannot claim that everything has disappeared and there is nothing there." 

"It is clear that there has been severe damage, but it's not total damage, first of all," IAEA director general Rafael Mariano Grossi said on "Face the Nation with Margaret Brennan." "And secondly, Iran has the capacities there; industrial and technological capacities. So if they so wish, they will be able to start doing this again."

The U.S. launched three strikes on Iran's nuclear facilities on June 21, following more than a week of Israeli attacks, which President Trump and Defense Secretary Pete Hegseth said had "obliterated" Iran's nuclear facilities.
