After Khadafi opened up his nuclear program to the US and Brits they found that had a large stockpile of yellowcake uranium.
Half of it had been smuggled in from Niger, and after some years declared to IAEA.
The other half he had subsequently smuggled in from Niger and never declared it until his “surrender”.
I only mention that because a number of years back we had people swearing that the very notion of uranium being smuggled out of Niger was preposterous.
75% of France's electricity comes from nuclear power which might help explain their interest in stopping Al Qaeda in Mali and sending more troops to Central African Republic. Lots of uranium in those countries.
