Director of National Intelligence Tulsi Gabbard announced Wednesday that new intelligence “confirms” that Iran‘s nuclear facilities targeted in the U.S. military‘s recent operation “have been destroyed,” and “would likely take years” to rebuild.

Gabbard’s latest comments on the effectiveness of the United States’s strikes on Iran’s Natanz, Isfahan, and Fordow facilities come amid a swirling controversy that raised doubts as to whether the facilities were damaged or destroyed.
