The GTI attributed more than 6,644 deaths to Boko Haram in 2014, with most attacks occurring in northeastern Nigeria. ISIS killed 6,073 in terrorist attacks in the same year, according to the report.
The GTI noted a 317 percent increase of terrorism deaths in Nigeria, the largest increase ever recorded by any country, where newly elected president Muhammadu Buhari has vowed to contain Boko Haram by the end of 2015.
