'Each year in the Mediterranean, as many as 9 ships suffer "suspect sinking."'
A sunken ship is termed a "suspect sinking" when officials believe, for a variety of reasons that depend on a host of factors, that a ship's owner has deliberately had her sunk. Often, these ships are believed to have dangerous cargo that the owners can't otherwise unload, such as radioactive waste. According to officials at one Italian university, there are as many as nine such suspect sinkings in the waters of the Mediterranean each year.
