On 26 March, the International Atomic Energy Agency (IAEA) said that UN inspectors visiting southern Libya had found drums containing natural uranium. In a statement to the Associated Press, the IAEA said inspectors visited the area on 21 March and saw the material being transferred to the storage site. However, they said that a ‘relatively small amount of UOC (Uranium ore concentrate) was still unaccounted for’ though clarified that there was no immediate radiological risk at the location. The statement said investigations were still underway on the matter including reconciling the quantities of natural uranium at the site with those previously verified by the IAEA. The IAEA said its director-general, Rafael Mariano Grossi, informed member states on 24 March about the findings of the visit.
