Iran has warned permanent United Nations Security Council members that no amount of pressure will make it abandon its nuclear program.

A Foreign Ministry spokesman, Hamid Reza Asefi, says Tuesday's meeting of the five permanent Council members plus Germany is of more importance to the participants than to Iran.

The talks in Moscow come a week before the full Security Council is to hear a report on Iran from the International Atomic Energy Agency. Russia says it still opposes using sanctions to persuade Iran to abandon its nuclear program.

In Washington, President Bush today reiterated that all options remain on the table with regard to Iran, but that he wants to resolve the issue diplomatically.

Mahmoud Ahmadinejad

Iranian President Mahmoud Ahmadinejad said today any aggressor would regret attacking his country.

Mr. Ahmadinejad spoke at a military parade in Tehran. He called Iran's military one of the world's most powerful armies.

Earlier this month, Iran carried out war games in the Persian Gulf and announced the testing of many new weapons. Among the Iranian-developed devices were a radar-evading missile and a high-speed, sonar-evading torpedo.
