Suspected Boko Haram insurgents dressed in Nigerian Army fatigues entered the Central Mosque in the Tsohuwar Kasuwa area of Konduga town during early morning prayers (approximately 5:00 am). Worshippers did not flee, believing the armed men were soldiers. Once inside, the militants opened fire with assault rifles and used explosives, throwing IEDs into the mosque during the attack. As survivors attempted to flee, they were cut down by a second group of insurgents stationed outside. The attackers also petrol‑bombed and destroyed around 50 homes in the vicinity, and targeted adjoining mosques in the town. The attack lasted about an hour.

Response
The military launched a pursuit operation in the nearby Sambisa fringe. This attack led to the massive scale-up of the Civilian JTF (CJTF) in Konduga, as locals realized the insurgents would no longer spare "fellow Muslims."

Tactical Deception
Trajectory
The Konduga mosque massacre marked Boko Haram‘s first large‑scale attack inside a mosque (previous attacks targeted individuals on their way to or from prayer). It represented a significant tactical escalation: the use of military camouflage to neutralise resistance before opening fire, combined with a secondary cordon to trap fleeing worshippers. This “pincer” tactic — attackers inside and outside — maximised casualties.
Cycle notes
The Konduga mosque massacre directly echoed the 5 April 2012 Maiduguri market attack, where gunmen disguised in military fatigues deceived and killed unsuspecting victims — both involved the use of military uniforms to enable mass casualty attacks. The reprisal motive — punishing a community for cooperating with the Civilian JTF — echoed the 27 July 2013 Dawashe reprisal, demonstrating a sustained insurgent strategy of collective punishment against populations perceived as collaborating with the state. The attack also mirrored the 1990s ethnic and communal violence in the Middle Belt, where local defence groups often drew retaliatory attacks on their home villages, but the scale and coordination — a mosque attack during dawn prayers using military deception — marked it as distinctly post‑2009 Boko Haram.

Approximately nine suspected Boko Haram/ISWAP terrorists, armed with AK-47 rifles, infiltrated Gajiram town through a porous section of the defensive trench dug by the military. They proceeded to Bakassi Joint, where they surrounded a group of youths playing cards and other local games.

Gunmen on motorcycles and motorised tricycles attacked two health centres in Kano where polio immunisation workers had gathered to prepare for a vaccination campaign. In the first attack, at the Hotoro district health centre, gunmen opened fire on the workers, killing at least seven. The victims were all female polio vaccinators. The attackers fled the scenes and no group immediately claimed responsibility, though suspicion fell on Boko Haram, which has consistently opposed Western medicine and polio vaccination campaigns.
A group of gunmen stormed Njilang village in Adamawa State, attacking both a church and a market. At least 10 residents were killed in the assault. Witnesses reported that the attackers arrived suddenly, opened fire on worshippers and traders, and fled after causing widespread panic.
