Ahmadinejad told the crowd in Azadi Square:

"God willing, the world will witness the inauguration of great achievements in the nuclear sphere in a few days."

He chastised the west for what he called its language of “force and insult,” saying that any talks with Iran over its nuclear program should be within the framework of “justice and respect.”

To mark the anniversary of the 1979 revolution, in which the pro-Western monarchy was toppled, tens of thousands of Iranians joined celebratory rallies across Iran.
