The US bombed Iran’s nuclear sites Fordow, Natanz and Isfahan on June 22.

United States President Donald Trump has insisted that the strikes on several of Iran’s nuclear sites last week “completely destroyed” the facilities, rejecting US media reports citing a Pentagon assessment that the attacks only set Tehran’s nuclear programme back by a few months.

An initial intelligence evaluation suggested that the US bombardment failed to destroy Iran’s underground nuclear facilities, The New York Times, The Washington Post and CNN reported on Tuesday, citing officials familiar with the military intelligence report from the Pentagon’s Defense Intelligence Agency (DIA).

Two people familiar with the assessment had told CNN that Iran’s “enriched uranium was not destroyed” and the centrifuges were “largely intact”.

Another source told the US broadcaster that, according to the assessment, enriched uranium had been moved before the US strikes on Sunday.
