General Treaty for the Cessation of Plunder and Piracy by Land and Sea
“ Article 2 If any individual of the people of the Arabs contracting shall attack any that pass by land or sea of any nation whatsoever, in the way of plunder and piracy and not of acknowledged war, he shall be accounted an enemy of all mankind and shall be held to have forfeited both life and goods. An acknowledged war is that which is proclaimed, avowed, and ordered by government against government; and the killing of men and taking of goods without proclamation, avowal, and the order of a government, is plunder and piracy. ”
