Seyyed Ali Khamenei

Addressing a group of visitors from the northwestern city of Tabriz on Wednesday, the leader said, "Iran will not allow a few countries to ruin the future of the world."

Ayatollah Khamenei further pointed out that Western countries spread lies about the Iranian nuclear energy program and the state of democracy and human rights in Iran because Tehran is determined to maintain its rights.

Meanwhile, the leader slammed US Secretary of State Hillary Clinton's comments during her recent tour of the Persian Gulf region, saying, "Yet again the Americans have sent their agent (Clinton) like a traveller to the Persian Gulf to repeat the same lies about Iran."

"However, nobody will believe their words anymore, as the United States has never cared about the interests of regional nations," the leader said, adding that "quite to the contrary, [Washington] has trampled on the rights of the regional countries".

Ayatollah Khamenei said that the US has turned the Persian Gulf into an arsenal, has attacked Iraq and Afghanistan and now is interfering in Pakistan.

"All the nations and most of the governments in the region are aware that the Islamic Republic supports peace, brotherhood, and dignity of the regional and all the Islamic countries," Khamenei said.

Ayatollah Khamenei also mentioned the mass rallies to mark the 31st anniversary of the victory of the Islamic Revolution.

"The enemies predicted that the rallies would plunge Iran into civil war," he said. "But the massive turnout of the Iranian nation was tantamount to a punch in the mouth for Iran's enemies."

Millions of Iranians took to the streets across the country on Thursday to celebrate the 1979 Revolution, which overthrew the US-backed Pahlavi monarchy.
