Iran's Supreme Leader Says: Tehran Will Not Stop Work On Nuclear Program

Iran's supreme leader says his country will not stop work on its controversial nuclear program. State television quoted Ayatollah Ali Khamenei as saying young Iranian scientists have guaranteed Iran's long-term energy security with their successes in nuclear science. He said a retreat would mean a complete loss. His comments Sunday came as Russia's national security chief, Igor Ivanov, met in Tehran with Iran's top nuclear negotiator, Ali Larijani.
