WASHINGTON (Reuters) -Commercial satellite imagery indicates the U.S. attack on Iran’s Fordow nuclear plant severely damaged - and possibly destroyed - the deeply-buried site and the uranium-enriching centrifuges it housed, but there was no confirmation, experts said on Sunday. “They just punched through with these MOPs,” said David Albright, a former U.N. nuclear inspector who heads the Institute for Science and International Security, referring to the Massive Ordnance Penetrator bunker-busting bombs that the U.S. said it dropped. But confirmation of the below-ground destruction could not be determined, noted Decker Eveleth, an associate researcher with the CNA Corporation who specializes in satellite imagery.
