Not a US ship and not Americans

Iranian patrol boats fired on a Marshall Islands-flagged cargo ship in the Strait of Hormuz and seized control of the vessel on Tuesday

There have been no reported injuries to the crew and no Americans are on board

Thanks for letting me know.

I just got online, and responded to a ping. Haven't read anything except headlines, and your post.
