U.S. President George W. Bush said Wednesday diplomatic moves to convince Iran not to develop nuclear weapons were "just beginning" but that he would not rule out other options. "It's vital that the Iranians hear the world speak with one voice," said Bush at a joint news briefing with German Chancellor Gerhard Schroeder. "I said all options are on the table ... but diplomacy is just beginning. Iran is not Iraq," said Bush. Earlier this year Bush caused alarm among many Europeans by saying he did not rule out military strikes against Iran over suspicions it is seeking to build a nuclear bomb. --SP 1445 Local Time 1145 GMT
