Some 400 European nationals have been taken hostage on foreign soil since 2000 - with more than one in ten dying in detention, according to a data-mining study of AFP news archives covering the period. The study, carried out jointly by AFP and a team of 10 journalism students from the Institut Français de Presse, analysed the contents of more than 40,000 AFP dispatches published between January 1, 2000 and March 31, 2015.
