Iran's offer to let a watchdog agency inspect the country's nuclear facilities is a stalling tactic to avoid UN penalties that would further isolate Tehran, Secretary of State Condoleezza Rice says. "I think they're playing games. But obviously, if they're not playing games, they should come clean. They should stop the enrichment, suspend the enrichment," Rice told ABC's "This Week" on Sunday. Iran's deputy oil minister played down the chance of UN action, saying punishing Tehran would send oil prices even higher. Tehran on Saturday offered to allow inspections if the UN Security Council would turn the dispute over to its nuclear monitor, the International Atomic Energy Agency. An agency report confirmed Iran had successfully produced enriched uranium and defied the Security Council's Friday deadline to stop the process.
