Here is an article written in 1998 at the Islamic Supreme Council website, which talks about Bin Laden having bought 20 nuclear warheads. It's four pages, too long to post, but here is the link ( it's in Adobe format)

House Committee of National Security Allegations of Russia's Missing Suitcase Bombs
October 1-2, 1997
In September 1997, General Alexander Lebed made international headlines with his allegations that over 100 small atomic demolition munitions were missing from the Russian nuclear arsenal. He asserted that the weapons were perfect terrorist devices as they were designed to resemble an ordinary suitcase and could be detonated by a single person with less than 30-minutes preparation. Any one of them, he warned, could kill 100,000 people.
