In a speech at a Tehran conference promoting Islamic studies and culture, Iranian President Mahmoud Ahmadinejad said that "America is facing a dangerous future" and that "the Great Satan" (i.e. the U.S.) will lose the battle.  

He called on Muslim clerics to invite all humanity to the true religion, Islam.

He added that "[the Zionist regime] is waving the banner of Satan."

Also participating in the conference were Ahmadinejad's spiritual mentor Ayatollah Mohammad Taqi Mesbah-e Yazdi, Iranian Revolutionary Guards commander Yahyah Rahim Safavi, Hizbullah Deputy Secretary-General Na'im Qasim, and other senior officials.
