Rice threatens sanctions on Iran over nuclear program

US Secretary of State Condoleezza Rice threatened Iran with more sanctions Thursday after it failed to give an adequate response to the latest bid by Western powers to induce it to freeze uranium enrichment. "You have to hope that there are reasonable people in Iran who see this as not the way to run a country." Tehran's latest response to a demand for the enrichment freeze in exchange for trade and technology incentives "is not a really serious answer," she said in her first comments since six world powers discussed the matter in a Wednesday conference call.
