Iranian president set to make nuclear announcement

President Mahmoud Ahmadinejad of Iran is due to make an announcement on its new generation of faster uranium enrichment centrifuges.

President Ahmadinejad said last week that his country would be announcing "great" nuclear achievements, adding that Iran would never halt its programme to enrich uranium.

In January the International Atomic Energy Agency (IAEA) confirmed that Iran had started the production of uranium enriched up to 20% at its Qom plant.

Western countries fear Iran is working towards making its own nuclear weapons, while Tehran insists its nuclear facilities are purely for energy purposes.
