[Ed. – Their investigation has led them to think the attackers used divers to attach limpet mines (magnetic mines with timed fuses or command detonation) below the water line on each of the four oil tankers. The bottom line on any scenario is that it involved the perpetrator being present at the time of the attack.]
The United Arab Emirates, Saudi Arabia and Norway said Thursday that a preliminary investigation into a coordinated attack on four of their oil tankers in an Emirati port last month was likely carried out by a state actor.
In a joint statement, they said limpet mines were used in the May 12 coordinated attacks, which left large holes in the hulls of the four tankers, but did not cause more extensive damage or oil spills. Limpets are a type of naval mine that attach to their target with magnets.
“It appears most likely that the mines were placed on the vessels by divers deployed from fast boats,” the statement said. “While investigations are still ongoing, these facts are strong indications that the four attacks were part of a sophisticated and coordinated operation carried out by an actor with significant operational capacity, most likely a state actor.”
