Islamist extremism remains the most threatening form of terrorism worldwide by far, according to the latest Global Terrorism Index (GTI) 2020 report. Among the top 20 states most vulnerable to terrorism, 19 of them are mainly targeted by armed Islamist actors.
The four deadliest terrorist organizations identified in the study are the Taliban, Boko Haram, the Islamic State, and the al-Qaida affiliated al-Shabaab group based in Somalia. These Islamist organizations were behind over half of the total deaths recorded in 2019.
