Iran has started the process of injecting uranium gas into centrifuges at its underground Fordow facility in the latest move away from its unravelling nuclear deal with world powers since the US pulled out of the landmark agreement in 2018.

Behrouz Kamalvandi, spokesman for the Atomic Energy Organisation of Iran, told state television the agency has delivered 2000 kilograms of Uranium or UF6 to the Fordow plant, under the supervision of United Nations inspectors, on Wednesday. 

KAN's Mark Weiss discussed the significance of the Iranian move with Dr Emily Landau, a senior research fellow at Tel Aviv's Institute for National Security Studies and head of the Arms Control and Regional Security Program.
