U.S. warns defiant Iran

By Fredrik Dahl

TEHRAN (Reuters) - The United States warned a defiant Iran on Wednesday that "all options are on the table" to thwart its nuclear ambitions and the EU's top diplomat prepared to travel to Tehran in the latest bid to resolve the dispute.

As part of carrot-and-stick diplomacy, European Union foreign policy chief Javier Solana said he would be in Iran on June 14-15 to discuss an offer by major powers of trade and other benefits if it halts uranium enrichment.

But the Islamic Republic made clear it had no intention of bowing to international demands and halting a nuclear programme which it says is aimed at generating electricity but which the West fears is a covert drive to build bombs.

President Mahmoud Ahmadinejad said Western pressure had failed to stop Iran's nuclear activities.

"With God's help today (the Iranian nation) have gained victory and the enemies cannot do a damned thing," he said in a speech broadcast live on state television.

The U.N. Security Council has imposed three rounds of limited sanctions on Iran since 2006 over its refusal to suspend nuclear enrichment, which can provide fuel for power plants or material for weapons if refined much more.

This week U.S. President George W. Bush said an "Iran with a nuclear weapon would be incredibly dangerous for world peace". On a farewell tour of Europe he threatened Tehran with more sanctions if it failed to stop enriching uranium.

Bush, who met German Chancellor Angela Merkel north of Berlin as part of his week-long tour of Europe, is pressing allies to agree new punitive measures against Iran.
