Interpol launched the Interpol Terrorism Watch List on 11 April 2002 for access by Interpol offices and authorized police agencies in its 184 member countries, during the 17th Interpol Regional Conference for the Americas in Mexico City. Following the September 11 terrorist attacks and United Nations Security Council Resolution 1373, Interpol took a number of steps, including the establishment of a 24-hour, 7 days a week command center and a linkage system to identify terrorist financing lists, to support its member countries' police forces.
