URGENT ¥¥¥ White House condemns Iran for nuclear upgrade 'escalation'

The White House warned Thursday that Iran's decision to install more modern equipment at its Natanz nuclear plant was a "further escalation" in the showdown over its atomic program.

"The installation of new advanced centrifuges is a further escalation and a continuing violation ... of Iran's obligations under relevant United Nations Security Council and IAEA board resolutions," White House spokesman Jay Carney said.
