IMO’s MSC has clarified that acts of piracy in the territorial seas of coastal States are named “Armed Robbery” to distinguish it from piracy which are acts committed in the High Seas. It is defined as follows:
“Armed robbery against ships” means any unlawful act of violence or detention or any
act of depredation, or threat thereof, other than an act of “piracy”, directed against a ship or against persons or property on board such a ship, within a State’s jurisdiction over such offences.
