Iran says it has developed a clutch of new nuclear centrifuges which can enrich uranium much faster. They are a key part of the process to generate nuclear power.

Iran’s President Mahmoud Ahmadinejad touted the new nuclear developments in a broadcast on state television yesterday, criticising “propaganda used against” his country, while footage showed him being shown around nuclear facilities with a host of scientists in white coats.

Fereydoon Abbasi Davani, head of Iran’s Atomic Energy Organisation said the centrifuges were three times more efficient than their existing capacity.
