On 5 December 2015, four suicide bombers attacked a weekly market on an island on the Chadian side of Lake Chad. The attack killed at least 15 people and injured approximately 130 others. The bombers were reported to be four women who carried out the attack at the market.
No organization publicly claimed responsibility for the bombings. Chadian officials suspected that the attack was carried out by members of Boko Haram, a militant group operating primarily out of neighboring Nigeria, though this remained a suspicion rather than a confirmed claim.
The attack fits into a broader pattern of violence attributed to Boko Haram in the Lake Chad Basin region during this period, an area straddling Chad, Nigeria, Niger, and Cameroon that experienced repeated attacks on civilian gatherings, including markets, in the mid-2010s.
No named suspects or defendants are identified in the available reporting.
