ISWAP terrorists, aided by local informants and sympathisers, attacked a military base in Kumuya, a village on the border of Borno and Yobe states and the hometown of former Army Chief Lt.-Gen. Tukur Buratai. The attack occurred when the Special Forces of the 27 Task Force Brigade, stationed at Buni Gari, had left for a clearing patrol. The insurgents stormed the Kumuya community, attacked villagers, and then descended on the base using heavy weapons, destroying equipment. They patrolled the area to prevent reinforcement, overwhelming the troops left behind. The base was set on fire, and troops on the ground were forced to withdraw in disarray. Following the attack, the military restricted movement along the Damaturu-Damboa-Biu road.

The use of local informants and sympathizers was crucial to the attack's success, demonstrating ISWAP's continued influence and intelligence-gathering capabilities in the region.
Trajectory
This attack was one of the most significant ISWAP operations in Yobe State up to that point, demonstrating the group's ability to strike deep into "liberated" areas.
Cycle notes
Mirroered earlier insurgent attacks including 18 November 2018 – Metele base overrun exploiting gaps in troop readiness, 04 March 2020 – Damboa Super Camp attack during active military operations, 15 January 2021 – Marte assault occurring amid troop redeployment, 01 March 2021 – Dikwa takeover leveraging initial military withdrawal, and 10 April 2021 – Damasak attack targeting both military and humanitarian assets, collectively reflecting a recurring pattern in which Islamic State West Africa Province exploits timing, local intelligence, and temporary force gaps—such as when troops are on patrol—to launch coordinated assaults on military bases, destroy infrastructure, and disrupt reinforcement efforts, highlighting the group’s growing intelligence network and operational depth in contested regions.
