“Israel”
Yeah that makes more sense than most other possibilities. I guess it could have been Iran, not officially sanctioned but some rogue elements. The Saudi’s and Israeli’s have big smiles on their faces today. Cui Bono? Not Iran I think.
PS The Iranian navy has submarines too.
“These eight ships are supported by three Russian built, SSK Kilo-class attack submarines and Ghadir and Nahang-class mini submarines.[7][8][9][10] ”
