Iran's supreme leader Ali Khamenei has hailed a day of rallies in support of the government, as estimates of the number of anti- regime protesters killed by his security forces continue to rise. The Ayatollah said it was a historic day which had thwarted Iran's enemies. He described the rallies as a warning to the United States and what he called its domestic mercenaries. A Norway- based Iranian rights group (Iran Human Rights) says it's now confirmed almost 650 victims of his government's violent crackdown on dissent. But it warned that some estimates exceed 6,000 dead. Witnesses have told the BBC the scale of the use of force was unprecedented.
