Well! Good for Iranian sailors but don't overlook the scary part of this news.
This did not happen in waters of Gulf of Adan or western Indian Ocean just of the shores of Somalia, it apparently happened just "northeast" of Fujairah UAE which is located just about 60 miles south of Bandar Abbas.
Not only Somali pirates have not disappeared or weakened but they were able to stretch their arms all the way up next to Hormuz.
