US Marines boarded a commercial vessel in the Gulf of Oman on Thursday, July 16, 2026, as part of a newly reinstated naval blockade targeting Iranian ports, according to US Central Command.
The operation involved the vessel M/T Wen Yao and was intended to enforce compliance with the blockade that began earlier in the week after the collapse of an interim peace deal.

US forces also redirected three other commercial ships attempting to bypass the security perimeter, Centcom confirmed.
Expanded Military Campaign
The boarding coincided with an expanded US airstrike campaign hitting southern Iranian infrastructure, including key bridges.
Iran retaliated with missile attacks toward Bahrain, Qatar, and Kuwait, further escalating tensions in the region.
These developments have significantly reduced cargo transit through the strategic Strait of Hormuz, a vital shipping lane for global oil supplies.
In a statement on social media, US Central Command said the boarding was conducted "to ensure full compliance with the ongoing US naval blockade."

The US President announced on social media that Tehran had released a US-Iranian citizen as a goodwill gesture.
Human rights lawyer Jared Genser identified the freed individual as Dena Karari, who had been charged with espionage.
