The gradual decline in the number of suicide bombings in 2018 and 2019 continued in 2020, with a 14.5 percent drop from the previous year. Most of the suicide bombings were concentrated in three countries: Afghanistan, Somalia, and Syria. There was also a steep drop in the number of victims. Salafi-jihadist organizations again accounted for a decisive majority of the world’s suicide bombings, and were directly or indirectly responsible for 95 percent of all such attacks. Whether the decline in suicide bombings in recent years results from the diminishing returns from this activity, or from a combination of the circumstances of the organizations involved and improved counteraction capabilities on the part of the countries attacked will become clear in the following decade.
