Salehi made the remarks while attending the rallies marking the 33rd anniversary of the Islamic revolution in Tehran.

The foreign minister told Press TV that the Western pressures on the Islamic Republic to abandon its "civilian" nuclear program will lead to nowhere.

"I think this is a good enough message for others to understand that this nation will never ever yield to pressures from outside," Salehi said, referring to the large turnout of people at Tehran's Azadi Square on Saturday.

This was Salehi's second confirmation in two days of Iran's determination to counter the Western pressure concerning Tehran's nuclear issue.

"Our nation should know that the Islamic Republic of Iran takes these threats seriously and we are prepared in every respect and have plans for the worst case scenarios. But we know that nothing will happen," Salehi said Friday.

He said that Iran will announce new nuclear achievements in the coming weeks, stressing the importance of confidence building between the West and Iran over Tehran's atomic case.  

"They should trust us and we will take the required measures within the framework of our nuclear safeguards," he said.

Salehi said Friday that it is possible that nuclear talks between Iran and the five permanent members of the United Nations Security Council plus Germany (G5+1) are to be held in the near future.

On Saturday, the Iranian president hailed Iran's achievements in diverse scientific areas including space technology and medicine and called as "successful" Iran's economic programs in the past years.
