The Taliban overtook ISIS as the world’s deadliest terrorist group in 2018, according to a report released by an international think tank on Nov. 20.
The 2019 Global Terrorism Index (pdf), now in its seventh edition, analyzed the impact of terrorism for 163 countries over the past year, using data from the Global Terrorism Database of the National Consortium for the Study of Terrorism and Responses to Terrorism. The results marked the first time since 2014 that ISIS was not the single deadliest terrorist group.
