TEHRAN, Iran - Iran says it is installing new and efficient centrifuges aimed at speeding up its nuclear enrichment.
The spokesman for the Iranian Foreign Ministry, Ramin Mehmanparast, made the announcement Tuesday.
The move comes despite four rounds of UN Security Council sanctions over Tehran's refusal to halt enrichment.
Iran says it wants to enrich only to power a future network of reactors and medical isotopes. Over the past two years it has started to enrich uranium to a level closer to the grade used to make the fissile core of nuclear warheads.
The West suspects Iran is pursuing a nuclear weapon program, a charge that Iran denies.
