In the early hours of Sunday, dozens of ISWAP (Islamic State West Africa Province) fighters in gun trucks and on motorcycles attacked the military base in Ajiri, a town in Mafa LGA about 20 km (12 miles) from Maiduguri. Troops fought a two‑hour gun battle, but the insurgents eventually breached the base, forcing troops to withdraw and escape with weapons. The commanding officer of the base was killed; at least six civilians caught up in the fighting were also killed. The attack was one of two simultaneous ISWAP operations that weekend — the other occurred in Rann, Kala‑Balge LGA, where insurgents in six gun trucks attacked a base but were repelled by troops using artillery.

Response
The Nigerian Air Force has been conducting airstrikes in the Lake Chad region. However, critics argue that the military's strategy of withdrawing to “super camps” has left rural areas more vulnerable to attacks
Displacement
0
Socioeconomic drivers
The attack demonstrated ISWAP's continued ability to launch coordinated, large-scale assaults on fortified military positions, as part of an intensified campaign against army camps
Trajectory
The assault on the base in Rann was repelled, but the Ajiri base was overrun. These simultaneous attacks on separate bases demonstrated ISWAP's ability to coordinate operations across a wide geographical area.
Cycle notes
The attack on the Ajiri military base in Borno State exemplified recurring insurgent patterns, as fighters arrived in gun trucks fitted with machine guns, stormed the town, engaged troops in intense fighting for around two hours, breached the fortified garrison, forced a withdrawal, and escaped with looted weapons. This directly paralleled the 15 January 2021 Marte base overrun (fierce assault shortly after repopulation efforts, with troops and residents fleeing), the 10 April 2021 Damasak assaults (multiple raids impacting military positions and a humanitarian hub, triggering major displacement), and the 25 April 2021 Mainok ambush (killing around 33 soldiers in a multi-phase attack with reinforcement challenges). The near-simultaneous strikes on Ajiri and Rann reflected ISWAP’s sustained tactic of multi-location operations to overstretch Nigerian forces — seen in earlier coordinated assaults — while the use of mobile firepower against isolated bases echoed longstanding methods from 2013 ambushes such as Baga-Maiduguri road and Monguno operations. Ajiri’s resettlement in August 2020 (approximately 500 households) made it a symbolic target, similar to Marte and prior Rann incidents where withdrawals left civilians exposed. The attack also highlighted criticisms of the military’s “super camp” strategy of concentrating troops in larger garrisons, which left rural areas vulnerable with delayed reinforcements, as noted in earlier cases like Dalori 2016 and Benisheik 2013. Follow-up violence around 3 May in the Ajiri/Rann area, killing soldiers, CJTF members, and civilians, further aligned with ISWAP’s pattern of repeat targeting vulnerable communities to maximize impact.

A gun battle near a mosque in Kano city and two other shootings left at least eight people dead. The deadliest incident occurred when gunmen opened fire around a mosque during Ramadan prayers, where a police team had been deployed to protect worshippers. Police exchanged fire with the attackers; one assailant was killed when his own explosive device detonated, while three other gunmen were shot dead. Among the victims were two Nigerian Air Force personnel. Civilians also fled in panic during the clashes.
