Terrorism in the seas and fighting against it is one of the issues discussed in international law, especially the international law of the seas, so that the first measures in this direction also go back to the era of the League of Nations. Maritime terrorism, especially in areas where other maritime crimes are prevalent, is considered a serious threat to the peace and security of the seas due to the creation of criminal links between the perpetrators of these crimes. The organized nature of these crimes makes fighting against them effective only through collective efforts. Meanwhile, due to the increasing spread of terrorist acts since 1963, several conventions to fight terrorism have been approved. Modern maritime terrorism has endangered maritime security and international trade so much that it has led to intervention by international organizations such as the International Maritime Organization. One of the challenges of dealing with maritime terrorism is the inefficiency of the tools to deal with it, included in the Convention on the Law of the Sea. In fact, maritime terrorism has been carried out using new technologies, but the tools to deal with it are old. For a serious fight against maritime terrorism, tools beyond this convention are needed.
