MIDDLE EAST — On September 21, a tanker on an inbound transit through the Strait of Hormuz was struck by an unknown projectile. Two crew members received minor injuries, after which the ship continued to its next port under its own power.
No environmental impact has been reported, and authorities are investigating the incident, according to the United Kingdom Maritime Trade Operations (UKMTO).
The vessel’s name, flag, and exact strike time have not been released. Military authorities passed the account to a maritime reporting center, which did not name a perpetrator.
US Mission To Saudi Arabia: Government Employees To The Kingdom Now Need Special Authorization For Travel
On September 20, the U.S. Mission in Saudi Arabia said U.S. government employees in the kingdom now need special authorization for official and personal travel to Taif and Yanbu.
The same day, U.S. Central Command said that as of that date its forces had redirected 109 commercial vessels to enforce compliance with the U.S. maritime blockade on traffic to and from Iranian ports, a blockade the command says resumed on July 14.
In a separate series of events inside the same waterway, the Joint Maritime Information Center listed three earlier Hormuz attacks in Update 098, covering March 1 through September 20.
That statement set the regional maritime threat level at SEVERE. One named ship in that list, the tanker MT Trend, was later claimed by Iran’s Islamic Revolutionary Guard Corps Navy.
