US Navy 'fired warning shots near Iran vessels' in Persian Gulf

Iran's elite Revolutionary Guard said a US navy aircraft carrier fired a warning shot in an "unprofessional" confrontation with Iranian vessels, the official IRNA news agency has reported.
IRNA quoted a statement as saying that the USS Nimitz and an accompanying ship came near an Iranian oil offshore platform in the Persian Gulf and a helicopter from the ship hovered near vessels manned by Iran's elite Revolutionary Guard.
