I can't stand it. These Somali pirates are great entertainment.
I think they probably attacked this ship knowing full well that it was- a French warship. Perhaps they never knew such a thing actually existed. A ghost ship. They were probably shocked as hell that the French Navy put up any kind of resistance at all. Maybe the worst they expected were some drunken frogs hurling the customary insults or flinging wine bottles at them.
Tough luck for me. I can't load the link. BBC is carrying the story. Pirates. French Navy. Keywords. Worth a chuckle.
