To add to their suspicions, some traces of low-enriched uranium found in Iran have yet to be explained, and may indicate more enrichment work than has been owned up to.

Iran would find it much harder to get foreign uranium for its enrichment machines, which Mr Ahmadinejad claims he set spinning merely to produce under 5% low-enriched uranium for nuclear-power reactors (though Iran has none that can use it), while others suspect it may eventually be used to make the 90%-enriched stuff needed for a bomb.
