Terrorists in northeast Nigeria killed a brigadier general in an assault on a military base, a local government chairman told AFP on Thursday, the second killing of a high-ranking officer in five months.
Africa’s most populous country has been fighting a terrorist insurgency for 17 years, since Boko Haram’s 2009 uprising, which has seen the emergence of powerful splinter groups, including Islamic State West Africa Province.
In an overnight attack, unidentified terrorists killed at least 18 soldiers and torched vehicles at a base in Benisheikh, about 75 kilometres from Borno state capital Maiduguri, an intelligence source told AFP.
“Unfortunately, the brigade commander, Brigadier General O.O. Braimah, lost his life,” Kaga Local Government Chairman Zannah Lawan Ajimi told AFP in a phone interview.
Two intelligence sources confirmed Braimah’s death to AFP.
His death follows the killing of Brigadier General Musa Uba by ISWAP in November. He was the highest-ranking military official to die in the long-running conflict since 2021.
“They overran the brigade,” one of the intelligence sources said, giving the death toll as “at least” 18.
The second intelligence source said that “the terrorists killed several troops” and “burnt vehicles and buildings before they withdrew,” without giving a toll.
The army and Nigeria’s Defence Headquarters did not immediately respond to a request for comment.
– Rising terrorist violence –
Researchers have warned of an uptick of violence since 2025.
Borno capital Maiduguri has seen two suicide bombings since December — the type of bloody, urban attacks reminiscent of the insurgency’s peak a decade ago.
On Wednesday, the US State Department said in a notice it was authorising “non-emergency US government employees” to leave Abuja “due to the deteriorating security situation”.
While the insurgency is concentrated in the northeastern countryside, terrorists from Nigeria and the neighbouring Sahel have made inroads western Nigeria, where organised crime gangs known as “bandits” have been raiding villages and extorting farmers and artisanal miners for years.
Gunmen killed at least 90 people across several remote villages in northwest Nigeria this week, according to an AFP tally of tolls given by local and humanitarian sources.
Among the attacks was an assault in Kebbi state that police blamed a local terrorist group known as Mahmuda, which is affiliated with Al-Qaeda.
Kebbi sits on Nigeria’s border with Benin and Niger and since 2025 has been targeted by a rising number of terrorist attacks.
Conflict monitor ACLED says there has been a surge in violence in the area carried out by militants affiliated with Al-Qaeda and the Islamic State group.
In nearby Kwara state, in October, fighters from the Al-Qaeda-affiliated JNIM claimed an attack after years of researchers warning that the terrorist conflict ravaging the Sahel risked spreading south towards coastal West African states.
In December, the United States, with Nigerian assistance, bombed northwest Sokoto state, targeting Islamic State Sahel Province fighters usually found in neighbouring Niger, along with Mali and Burkina Faso.
