According to three U.S. officials who spoke to NBC News, eight U.S. Marines — one officer and seven enlisted — were injured on September 14 when an Iranian cruise missile struck a vessel they were operating in the Strait of Hormuz. Officials said none of the injuries were serious, but the Marines suffered smoke inhalation and symptoms consistent with concussions, including possible traumatic brain injuries. They returned to duty soon afterward. The vessel was not a U.S. Navy ship; officials described it only as a “maritime vessel” and would not identify its type or flag. The Pentagon did not publicly announce the attack, and the eight injuries were added to the Defense Department’s casualty database about ten days later, alongside 29 Navy sailors. Some outlets tie the incident to a broader, disputed U.S. casualty count in the Iran conflict.

What is contested

Where accounts differ

Points the coverage does not agree on, and who says what.

  • The overall U.S. casualty total in the Iran war

    Truthout describes casualties as “approaching 900,” while The Intercept cites an official Pentagon count of 880 wounded or dead, with 444 of those since July 7.

  • Who is responsible for the non-disclosure of the attack

    Daily Mail frames the story as an accusation that Secretary of War Pete Hegseth personally covered up the injuries, while NBC and other left-leaning outlets describe the non-disclosure as a Pentagon or Defense Department failure without naming a specific official as the target of blame.
