Tehran: Iran is "to inaugurate important nuclear projects in the next few days," President Mahmoud Ahmadinejad said on Saturday, adding that his nation "will never yield" to Western coercion aimed at stopping its atomic activities.

Ahmadinejad, giving a speech in Tehran marking the 33rd anniversary of Iran's Islamic revolution, gave no details of the nuclear projects.

But he railed against Western economic sanctions imposed to force Iran to give up its controversial nuclear programme, and at threats of possible Israeli and US military action against Iranian nuclear facilities.

"If the language of bullying and insult is used, the Iranian nation will never yield," he said.

"The only path is to adhere to justice and the respect of Iran's (nuclear) rights and to return to the negotiating table," he said. Otherwise, the West will continue to face "defeat" on the issue, he said.
