00:00Have U.S. strikes obliterated Iran's nuclear facilities?
00:08U.S. officials say Operation Midnight Hammer has set back Iran's nuclear program.
00:14We devastated the Iranian nuclear program.
00:18We've been looking at satellite imagery to estimate the degree of destruction at the three sites targeted.
00:24Fordow, Natanz and Isfahan.
00:27This is Iran's most secretive uranium enrichment site buried into the mountainside in Fordow.
00:34And this is Fordow after the strikes.
00:37Six penetration holes can be seen where the U.S.'s 13,000 kilogram GBU-59 bunker-busting bombs hit what experts believe are ventilation shafts that link to the underground enrichment holes.
00:52We can also see ash and discoloration on the mountain due to the underground explosion.
00:57These bunker-busters work like a needle, penetrating as much as 60 metres underground before exploding in order to destroy subterranean facilities such as Fordow's.
01:07And this is Natanz, Iran's largest nuclear enrichment centre, which was also impacted by a bunker buster here.
01:16Experts say this point is directly above the underground enrichment holes.
01:21Experts we've spoken to all say these images suggest significant destruction.
01:26But this image, taken at Fordow, hours before the attack, shows as many as 16 trucks stationed along the access road.
01:35It means Iran could have moved some of its highly enriched uranium to an undisclosed location at the last minute in order to preserve it.
01:43While emerging evidence suggests key Iranian nuclear facilities have suffered major destruction,
01:48it's too early to tell to what extent it set back Tehran's nuclear programme.
