 Interpol now has more than 40,000 profiles of foreign terrorist fighters in its databases, accessible by national police and border services in its 192 member countries. Whilst it is processing tens of thousands more names and pieces of information shared by member countries and establishing additional foreign terrorist fighter profiles, information is key in generating investigative leads. Connecting the dots means we must exploit information left behind by foreign terrorist fighters. We need to collect and consolidate information on IS, which is still in the battlefield or in the hands of authorities, so it can reach the global community.
