This was indeed a treacherous act by a gang of armed thugs. The fact that these pirates are now attacking a large cruise ship this far from land is most unsettling indeed. I personally would not travel that part of the open sea until this matter is resolved through an international joint effort.
As an aside, I did find it more than amusing to read that MSC only days before the incident was advertising a balcony blowout sale.
Talk about bad timing.
