In a further provision, the Council called on Member States to assist Somalia, at the request of the Transitional Federal Government, in strengthening capacity in the country, including regional authorities, to bring to justice those involved in piracy who were using Somali territory for planning or undertaking their criminal acts. It called upon all States to cooperate in determining jurisdiction and in the investigation and prosecution of all persons responsible for acts of piracy off the coast of Somalia, as well as to criminalize piracy under their domestic law.
