The operation follows a major joint breakthrough on Saturday, where U.S. and Nigerian forces killed Abu-Bilal al-Minuki. According to U.S. President Donald Trump and Nigerian President Bola Ahmed Tinubu, al-Minuki was the second-in-command of the Islamic State globally.

Military officials confirmed that the subsequent Sunday operations targeted remaining terrorist elements in the region without suffering any casualties.

“Intelligence confirmed the targets were ISIS militants. Complete assessments are ongoing. No U.S. or Nigerian forces were harmed,” read a statement shared by the U.S. Africa Command on its website.

The back-to-back military actions mark a significant blow to the extremist group's operational infrastructure in West Africa.

Following the latest strikes on Sunday, the U.S. Africa Command said that “the removal of these terrorists diminishes the group’s capacity to plan attacks that threaten the safety and security of the U.S. and our partners.”

The command added that the U.S. Africa Command remains committed to using specialised U.S. capabilities to support partners in defeating shared security threats.
