The report, released on November 16, 2015 by the Institute for Economics and Peace, said the Islamist terror group in Nigeria, Boko Haram, overtook ISIL in 2014 to become the most deadly terrorist group in the world.
The Institute for Economics and Peace is an independent, non-partisan, non-profit think tank with offices in Sydney, New York and Mexico City.
The 2015 GTI report said Boko Haram, in 2014, was also able to spread outside Nigeria to launch two deadly attacks in neighbouring Cameroon, killing 530 people.
