How Brig. Gen. Oseni Braimah Died
On 9 April 2026, suspected ISWAP terrorists launched a coordinated attack on the 29 Task Force Brigade Headquarters in Benisheikh, Borno State. The attack began at approximately 12:30 a.m.
The Attack on Benisheikh
The insurgents attempted to breach the defensive perimeter of the military installation using heavy gunfire and explosives. According to the Defence Headquarters, the troops responded under Braimah’s command. The military described the response as one of exceptional courage and superior firepower, forcing the attackers to retreat.
However, the encounter resulted in heavy casualties. The Chairman of Kaga Local Government Area, Zanna Ajimi, confirmed that the Brigade Commander was among those killed. He told journalists that he had personally visited the military base after the attack.
Scale of the Attack
The Benisheikh assault was part of a broader coordinated attack that also targeted Ngamdu and Pulka communities in Borno State. Across the three locations, at least 18 soldiers and officers were killed, including Braimah, his second-in-command, and the brigade’s Imam. The attackers also set combat vehicles and commercial trucks ablaze along the Maiduguri–Damaturu highway.
Security sources suggested that the simultaneous attacks on Ngamdu and Banki Ruwa may have been diversionary tactics aimed at delaying Nigerian Air Force reinforcements.
