A senior US official said here on Friday that it would be "major miscalculation" by the government of Iran if it insists to install 3,000 centrifuges for the production of uranium enrichment.

"If Iran takes this step, it is going to confront universal international opposition," Undersecretary of State Nicholas Burns said at a news briefing.

"If they think they can get away with 3,000 centrifuges without another Security Council resolution and additional international pressure, then they are very badly mistaken."

The UN Security Council passed Resolution 1737 on Dec. 23, 2006,calling on Tehran to suspend its enrichment activities and imposing sanctions on Iran's nuclear and missile programs but was rejected by Iran who vowed to install at least 3,000 centrifuges by the end of March.
