Iran's government has no legitimacy left: Rice

Iran`s government has no legitimacy left: Rice Washington: Former Secretary of State Condoleezza Rice says the US should consider even tougher penalties against Iran's government and "be doing everything we can to bring it down."

Rice tells ABC television's "This Week" that the US should never take the option of military force off the table when it comes to dealing with Iran.

She says the current Iranian government is trying to obtain a nuclear weapon and has repressed its own people. Rice says "the regime has absolutely no legitimacy left."

Diplomats have said that the UN atomic agency plans to disclose intelligence this coming week suggesting that Iran made computer models of a nuclear warhead.

Iran says its nuclear programme is only for peaceful aims such as energy production.
