The heads of two key American intelligence agencies issued statements Wednesday on what they said was "new" intelligence on the damage resulting from the recent US strikes on Iran's nuclear facilities, each noting the Iranian program was likely to have been set back by "years," reports CBS News.

The statements were released after President Trump decried a leaked, preliminary assessment produced by the Defense Intelligence Agency that said Tehran's nuclear program had only been pushed back by a matter of months.

CIA Director John Ratcliffe said in a statement Wednesday that "a body of credible intelligence indicates Iran's Nuclear Program has been severely damaged by the recent, targeted strikes."

“This includes new intelligence from a historically reliable and accurate source/method that several key Iranian nuclear facilities were destroyed and would have to be rebuilt over the course of years," Ratcliffe's statement said.

Earlier on Wednesday, Director of National Intelligence Tulsi Gabbard also wrote on X that "new intelligence confirms what President Trump has stated numerous times: Iran's nuclear facilities have been destroyed.”

“If the Iranians chose to rebuild, they would have to rebuild all three facilities (Natanz, Fordow, Esfahan) entirely, which would likely take years to do," Gabbard's statement read.

An intelligence official later confirmed to CBS News that the information shared by Gabbard was based on new American intelligence, but declined to specify its confidence level.

Neither of the statements directly addressed some of the questions raised by lawmakers and nonproliferation experts in the aftermath of the strikes about what kinds of residual nuclear capabilities Iran may have retained.
