Khamenei blames Iran's 'enemies' for unrest as US ups the pressure

Iran's supreme leader blamed "enemies" Tuesday for unrest that has seen 21 deaths as Washington sought to increase pressure on the Islamic regime that was facing its biggest test in years. In a speech carried on state television, Ayatollah Ali Khamenei broke his silence on the protests for the first time since they erupted last Thursday. "The enemies have united and are using all their means, money, weapons, policies and security services to create problems for the Islamic regime," the supreme leader said.
