Iran using 100s of centrifuges at Natanz: Elbaradei

RIYADH (Reuters) - Iran, which says it is enriching uranium on an industrial scale, is still using only hundreds of centrifuges at its Natanz facility, the head of the U.N. atomic watchdog said on Thursday.

"(Iran) is still going ahead with the construction of the Natanz reactor ... with the goal of having 54,000 centrifuges. Now it is still at the hundreds stage," Mohamed Elbaradei, head of the International Atomic Energy Agency, told reporters in Riyadh.

Iran said on Monday it had begun industrial enrichment of uranium and injected uranium gas feedstock into a batch of 3,000 centrifuges it is building.
