The United States denounced Iran's claimed test of a new medium-range missile on Wednesday and warned Tehran to halt its ballistic missile program "immediately" amid a nuclear dispute with the West. "Iran's development of ballistic missiles is contrary to United Nations Security Council resolutions and completely inconsistent with Iran's obligations to the world," said White House spokesman Gordon Johndroe. Johndroe said the United States and its partners in talks with Iran over its suspect nuclear program "are committed to a diplomatic path" and to "generous" rewards if the Islamic republic freezes its uranium enrichment activities.
