The Legal Committee of the International Maritime Organisation (IMO), a UN body on maritime issues, had called upon contracting states to work on two Protocols and introduce substantial amendments aimed at strengthening the Convention for the Suppression of Unlawful Acts against the Safety of Maritime Navigation also known as the SUA Convention. The SUA convention has been adopted by 126 countries representing 82 percent of the world's merchant fleet and provides for an appropriate response to the risks posed to maritime navigation by international terrorism.
