Iran claims to have smuggled almost all of the country’s highly enriched uranium to a secret location before the US launched strikes on its nuclear bases.
Iran has vowed to continue enriching uranium in defiance of Donald Trump, raising further concerns over its nuclear programme.
Two Israeli officials with knowledge of the intelligence told The New York Times that Iran had transferred equipment and uranium outside Fordow in recent days.
There was also evidence to suggest Iran had moved its 400kg stockpile of 60 per cent enriched uranium, which had been stored inside Isfahan, to a secret location.
Uranium enrichment is the process of increasing the concentration of the uranium-235 isotope in natural uranium.
Iran enriches uranium using centrifuges, which spin uranium hexafluoride gas at high speeds to separate the uranium isotopes, increasing the concentration of U-235.
As of May 17, Iran had amassed 408.6kg (901lb) of uranium enriched up to 60 per cent, a report by the IAEA found. »
