Boko Haram jihadists attacked two fishing islands in Lake Chad in a coordinated operation. The attackers first struck Duguri island, killing 12 fishermen and wounding two others who later died (bringing the Duguri toll to 14). The attackers then split into two groups; while the first group attacked Duguri, the second went to nearby Dabar Wanzam island, where they lay in wait for fishermen who fled the first attack, killing 17 there. The attackers spared one fisherman in Duguri, loading the 12 bodies of those killed into a canoe and ordering him to take them to Baga as a warning. They also instructed the spared man to "inform the troops in Baga that they were waiting for them on the islands."

Cycle notes
Mirrored earlier attacks by Boko Haram including the 16 February 2017 multi-phase Maiduguri attack combining initial strikes with follow-on engagements, the 11 July 2017 attack on mourners as a secondary strike pattern, the 20 June 2017 ambush on the Maiduguri–Damboa highway targeting vulnerable segments after movement disruption, repeated 2013–2015 village raids involving the pursuit of fleeing civilians (such as Gumsuri and surrounding Borno communities), the 19 November 2017 Dimge farmers’ execution involving capture and the use of a survivor as a messenger, and the 2014 Chibok/Damboa axis raids where spared survivors were used to spread terror, collectively reflecting a recurring pattern of “double-tap” or sequential targeting in which Boko Haram conducts an initial attack to displace victims and then strikes anticipated escape routes or gathering points to maximize casualties, while also employing psychological warfare through deliberate messaging to reinforce territorial dominance and deter economic activity, particularly in the Lake Chad Basin.

Boko Haram militants carried out coordinated bomb and gun attacks in Potiskum, Yobe State, killing at least 23 people. Several government buildings and schools were set ablaze during the assault.
In a massive nighttime assault, dozens of Boko Haram gunmen launched a coordinated raid on the Gombe State Police Command Headquarters and a nearby divisional station. The attack began with the detonation of several improvised explosive devices (IEDs) to breach the perimeter, followed by a heavy firefight using assault rifles and rocket-propelled grenades (RPGs). The insurgents aimed to overawe the state's security apparatus and likely targeted the armory and detention cells.
Gunmen invaded the Ansarudeen Private School in the Jajeri ward of Maiduguri. They opened fire on students who were writing their final year examinations.
