Foreign ministers from the five permanent members of the U.N. Security Council and Germany say Tehran is not serious in negotiations to end its nuclear enrichment program. With Tehran hesitating to respond to a proposal from the group, Secretary of State Condoleezza Rice and her colleagues agreed to refer Iran back to the Security Council for possible punishment.
The six powers have sought an Iranian response to an incentive package before the weekend summit of the Group of Eight industrialized nations in St. Petersburg, Russia. But Iranian officials have insisted they won't present a formal response until August.
Tehran was referred to the Security Council earlier this year, but work on a U.N. resolution was delayed to allow the Iranian leadership to respond to the EU incentives, which included a state-of-the-art nuclear reactor with a guaranteed fuel supply, and other economic benefits
The six foreign ministers, meeting in Paris, said they will seek an initial resolution requiring Iran to suspend its uranium enrichment. If Iran does not comply, harsher action such as sanctions will be sought.
