Iran tested more missiles in the Gulf on Thursday, state media said, and the United States reminded Tehran that it was ready to defend its allies. Washington, which accuses Tehran of seeking nuclear arms, said after Iran test-fired nine missiles on Wednesday there should be no more such tests if Iran wanted the world's trust. US Secretary of State Condoleezza Rice said on a visit to the former Soviet republic of Georgia that no one should be confused about Washington's commitment to protect its allies. “We are also sending a message to Iran that we will defend American interests and ... the interests of our allies,” she said after meeting Georgian President Mikheil Saakashvili. Rice said a planned US missile defense shield, to be partly based in the Czech Republic and Poland, would dampen any threat of an attack from Iran. Russia opposes the project. “We also are able to look to the future of a missile defense system that will make it more difficult for Iran to threaten (and) and be bellicose and say terrible things because their missiles won't work,” Rice said. Iranian state TV and radio said the Revolutionary Guards – the ideologically driven wing of Iran's armed forces – had fired ground-to-sea, surface-to-surface and sea-to-air missiles overnight. Long-range missiles were also launched.
