Iran on Wednesday said it warned a U.S. Navy destroyer to change course as it moved through waters close to Iran, but a U.S. defense official said the interaction was safe and professional and had no impact on its mission.

Iran deployed a naval helicopter to warn off a U.S. Navy destroyer in the Gulf of Oman, the country's state media reported, in a clash Tehran says forced the American vessel to retreat. Newsweek has contacted the United States Naval Forces Central Command's press affairs section via email for comment.
