Iranian President Mahmoud Ahmadinejad dismissed UN sanctions against Tehran over its nuclear program as having "no effect" Thursday as the country kicked off celebrations to mark the anniversary of the 1979 Islamic Revolution.

"The enemies know that sanctions imposed on the country will have no effect," the official IRNA news agency quoted Ahmadinejad as saying at the mausoleum of the late Iranian Supreme Leader Ayatollah Ruhollah Khomeini.

The Iranian president and his cabinet members, accompanied by Khomeini's grandson Hojjatoleslam Hassan Khomeini, paid tribute to the father of the Islamic Revolution on the first day of the Ten-Day Dawn ceremonies.

Iran holds the Ten-Day Dawn celebrations on Feb. 1-11 every year to mark the victory of the 1979 Islamic Revolution, which overthrew the monarchy of the Iranian shah and established the Islamic Republic.

"Despite pressure from the enemies, certain countries continue to express favorable stances on the Iranian nation's right to peaceful nuclear energy," Ahmadinejad said.

"If bullying states mobilize all resources in their power they still cannot do anything," he said. "At most, they can take measures that will irritate but will have no impact on the Iranian nation's will."

He noted that Iranians will display their power and unity by massively participating in the Feb. 11 rallies which will culminate the celebrations of the revolution anniversary.

The UN Security Council adopted Resolution 1737 on Dec. 23, 2006, demanding Iran suspend all enrichment-related and reprocessing activities but Iran has rejected the resolution as an "illegal measure" and vowed to continue the country's nuclear programs.
