Supreme Leader Ayatollah Ali Khamenei denounced on Sunday what he called "interfering statements" by Western officials following Iran's disputed presidential election, state media reported, Reuters reported. "If the (Iranian) nation and officials are unanimous and united, then the temptations of international ill-wishers and interfering and cruel politicians would no longer have an impact," state radio quoted Khamenei as saying. Iran has accused Western powers -- Britain and the United States in particular -- and media of fomenting street protests and violence that rocked the Islamic Republic after its June 12 election. Britain has rejected the accusations.
