TEHRAN, July 10 (Reuters) - 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.

The United States, which accuses Tehran of seeking nuclear arms, said after Iran test-fired nine missiles on Wednesday that there should be no more such tests if Iran wanted the world's trust. An intelligence official in Washington said there had been a second test and that it was small.

U.S. leaders have not ruled out military options if diplomacy fails to assuage fears about Iran's nuclear program, which Tehran says is only to produce electricity.
