For the first time since CEP reporting began in December 2022, the number of monthly attacks claimed by al-Qaida and ISIS affiliates in West Africa exceeded 90. In December 2023, the claimed number of attacks averaged three per day, just short of 100. This supports earlier CEP predictions that the number of claimed attacks would continue to increase in 2024. At the beginning of CEP’s reporting, regional terror groups claimed on average 38 attacks monthly. This increased steeply during 2023. A first peak was reached during the month of Ramadan 2023, which coincided with April 2023 with a total of 68 claimed attacks. After this peak the numbers somewhat stabilised again on a higher level. However, since October 2023, the monthly level of claimed terrorist violence by al-Qaida and ISIS affiliates in the region has continued to reach unprecedented levels. With 96 claimed attacks in December 2023, the year-by-year increase stands at 252.63 percent.
