Suspected Boko Haram or ISWAP insurgents raided the Gajibo IDP camp, setting fire to approximately 30 newly built houses. The houses were constructed by the Borno State government as part of a resettlement programme for returning internally displaced persons (IDPs). The attackers fired sporadically into the air before setting the structures ablaze.

The Ali Ngulde-led faction of the Jamā'at Ahl as-Sunnah lid-Da'wah wa'l-Jihād (Boko Haram) carried out a public execution of one of its top military commanders, Abou Hassana (also referred to as an "Amir Jaysh" or Leader of the Army), along with three of his alleged accomplices. The executions took place in front of a gathering of other fighters at Mandara Mountain in Gwoza Local Government Area of Borno State, a location that once served as a major stronghold of the group. Abou Hassana was accused of attempting to raise an independent faction within the group to lead his own terror campaigns in Koltafirgi village (also known as Gaizuwa in Sambisa Forest). According to security analysts, Hassana and his co-accused were tried by the group's leadership, sentenced to death, and then publicly eliminated. The execution was ordered by Ali Ngulde, the second highest-ranking leader in the Boko Haram hierarchy, as a decisive measure to crush internal dissent and maintain the faction's cohesion. Following the executions, Alhaji Ari Hajja Fusam, a native of Bama who had previously led Boko Haram fighters in Gaizuwa before being dislodged by the military, was promoted to replace Hassana.

Following the twin bombings in Zaria, a third suicide bomber drove a vehicle laden with explosives (VBIED) into the Shalom Church in the Trikania area of Kaduna South. This blast was the final trigger in a coordinated "triple-strike" across the state. Because Trikania is a densely populated and volatile neighborhood in the southern part of the capital, this specific attack acted as the immediate catalyst for the mass sectarian riots that consumed Kaduna city for the following 48 hours.

Gunmen suspected to be members of Boko Haram stormed the Mafa police station in Borno State, approximately 40 kilometres (25 miles) from the state capital, Maiduguri. The attackers, arriving in vehicles, fired sporadically and used explosives to set the station ablaze, destroying the building. Two policemen and one civilian were killed in the attack, which occurred on the same night as a separate Boko Haram assault on the nearby Jakana police station, where one policeman and a woman were killed.
