Nigeria's President Bola Tinubu and the west African country's military on Saturday confirmed the killing in Nigeria of a senior ISIS leader in a joint operation with US forces.
"Our determined Nigerian Armed Forces, working closely with the Armed Forces of the United States, conducted a daring joint operation that dealt a heavy blow to the ranks of ISIS," Tinubu said in a statement after US President Donald Trump first announced the killing.
Abu-Bilal al-Minuki was the second-in-command of ISIS worldwide, according to Trump.
He was killed overnight, according to both Trump and Tinubu.
Tinubu said in a statement that Al-Manuki, also known as Abu-Mainok, was killed "along with several of his lieutenants, during a strike on his compound in the Lake Chad Basin".
The Nigerian defense forces said al-Minuki was a "senior ISIS leader and one of the world's most active terrorists".
It described him as an "operational and strategic figure who provided guidance to ISIS entities outside Nigeria on matters relating to media operations, economic warfare and the development and manufacturing of weapons, explosives and drones".
It said his "death removes a critical node through which ISIS coordinated and directed operations across different regions of the world".
Nigeria is battling extremist insurgents, including regional offshoots of the ISIS organization, as well as extremist rival Boko Haram. It has also carried out strikes and operations against non-ideological violent gangs of criminals known as "bandits".
Since late 2025, the Nigerian government has been under pressure from the United States, which has accused it of not doing enough to combat the extremist militant threat.
On Christmas Day, the United States, in collaboration with Nigerian authorities, carried out airstrikes in northwestern Sokoto State targeting fighters from the ISIS in the Sahel group, usually active in neighboring Niger.
Washington has since deployed hundreds of troops to Nigeria to support and train its forces.
