Eight US Marines were injured after an Iranian cruise missile struck a commercial vessel in the Strait of Hormuz on September 14, 2026, according to three US officials cited by NBC News.
The service members suffered smoke inhalation and symptoms consistent with traumatic brain injury, including concussions and severe headaches.
All eight have since returned to active duty, the officials said.
The Pentagon has recorded more than 800 American service personnel injured in the military conflict with Iran since the start of the year.
Authorities did not disclose the identity of the vessel or its type.
Officials confirmed the targeted ship was not a US Navy warship, matching private maritime security reports of a Western-operated vessel hit that day.
Shipping Traffic Stabilizes Despite Strikes
International shipping through the southern corridor of the Strait of Hormuz has stabilized despite the persistent attacks.
Supertanker traffic has recovered to more than 10 million barrels per day under ongoing oversight by US Central Command.
Separately, Iranian forces claimed the seizure of a US Navy Remus 600 intelligence-gathering drone in the waterway.
The claim follows a prior incident involving a disabled Anduril Dive-LD unmanned submersible.
