Four countries suffer 80% of losses
The data gathered by the BBC found that 5,042 people were killed in 664 jihadist attacks across 14 countries – a daily average of 168 deaths, or seven every hour.
About 80% of the deaths came in just four countries – Iraq, Nigeria, Syria and Afghanistan, according to the study of media and civil society reports.
Iraq was the most dangerous place to be, with 1,770 deaths in 233 attacks, ranging from shootings to suicide bombings.
In Nigeria, 786 people, almost all of them civilians, were killed in 27 Boko Haram incidents. These tended to be large and indiscriminate bombings and shootings such as the attack on the central mosque in the northern city of Kano, which left 120 dead.
