US chides Iran on plan to speed up nuclear fuel work

The White House said on Thursday that Iran's plan to install advanced uranium enrichment machines at its main enrichment plant near the central town of Natanz would be a "provocative step" in further violation of United Nations resolutions against Tehran's nuclear program.

"This does not come as a surprise," White House spokesman Jay Carney told reporters. He said the introduction of new centrifuges would result in Iran's further isolation by the international community. (Reuters)
