ANKARA - Iran's Supreme Leader said on Thursday he backed a parliamentary vote on a historic nuclear deal reached with six major powers and said sanctions against his country should be lifted completely rather than suspended, state television reported."The parliament should not be sidelined on the nuclear deal issue ... I am not saying lawmakers should approve the deal or reject it. It is up to them to decide," Ayatollah Ali Khamenei said."Sanctions imposed on Iran should be lifted and not only suspended ... If not, then we will only suspend our nuclear activities ... Our officials only discuss the nuclear deal with America ... We will never support America's policies on Syria and Iraq."
