Supreme leader Ayatollah Ali Khamenei says Iran will deliver a “punch” that will stun the Western world during this week’s anniversary of the Islamic revolution. "The Iranian nation, with its unity and God's grace, will punch the arrogance (Western powers) on the 22nd of Bahman (February 11) in a way that will leave them stunned," Khamenei told a gathering of air-force employees, reports AFP. These comments come on the heels of Iran’s announcement that it will begin to produce enriched uranium despite worldwide protest and threats of sanctions. Opposition protesters are expected to take to the streets in demonstrations and marches on the February 11 anniversary. "The clerics should know that since imprisonment, beatings, and other confrontational methods are done in the name of Islam and the Islamic regime, it is hurting Islam and we all should try to stop," said opposition leader Hossein Mousavi on his Web site.
