U.S. and Nigerian forces launched another strike against ISIS fighters in Nigeria, according to U.S. Africa Command (AFRICOM), just days after they carried out an operation that killed a global ISIS leader.

AFRICOM said it conducted the additional kinetic strikes against ISIS militants on Monday in coordination with Nigeria’s government. It said complete assessments are ongoing, though noted that no U.S. or Nigerian forces were harmed during the operation.

"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," AFRICOM said.

The strikes come after President Donald Trump announced late Friday that U.S. and Nigerian forces killed Abu-Bilal al-Minuki, whom he described as ISIS’s second-in-command globally.

"Abu-Bilal al-Minuki, second in command of ISIS globally, thought he could hide in Africa, but little did he know we had sources who kept us informed on what he was doing," Trump wrote in a post on Truth Social at the time. "He will no longer terrorize the people of Africa, or help plan operations to target Americans."

Secretary of War Pete Hegseth confirmed Saturday that U.S. forces, in coordination with the Armed Forces of Nigeria, killed al-Minuki and other ISIS leaders.

"So, for months, we hunted this top ISIS leader in Nigeria who was killing Christians, and we killed him — and his entire posse," Hegseth wrote.

The announcement also comes after U.S. Central Command (CENTCOM) said it carried out multiple strikes against more than 30 ISIS targets in Syria in February as part of a joint military effort to "sustain relentless military pressure on remnants from the terrorist network."

Abu-Bilal al-Minuki, ISIS’s shadow commander in West Africa, was killed May 16 using what an extremism analyst describes as one of the hardest forms of intelligence to detect, after decades being shielded by "deep local networks" across the region.

While the killing dealt one of the biggest blows to ISIS’s global network in years, disrupting operations in northeastern Nigeria, the terror group's top leader, Abu Hafs al-Hashimi al-Qurashi, remains at large as Africa becomes the movement's global epicenter.

"There is no single ISIS ‘headquarters’ in Nigeria; ISWAP (Islamic State West Africa Province) operates dozens of small, shifting camps scattered across the Lake Chad islands and the Borno bush," Dr. Omar Mohammed, Senior Research Fellow at the GW Program on Extremism, told Fox News Digital.

"Al-Minuki would have had no smartphones, relying instead on courier-based communications and constant movement between these small camps," he said.

President Donald Trump’s explicit reference to "sources who kept us informed" points directly to human intelligence, or HUMINT — the hardest form of intelligence for a target to detect or counter, Mohammed explained.

The precision strike successfully penetrated defenses that had been held for years.

"He would have utilized deep local networks the Nigerian military has struggled to penetrate for over a decade," Mohammed added.

"His operational security would have been severe," Mohammed said. "But two things eventually undo even careful targets: time generates patterns, and human sources are extremely difficult to defeat."

"Despite severe operational security, al-Minuki was ultimately compromised through persistent human intelligence," he noted. "Al-Minuki knew he was marked."

The Nigerian army described the strike as "a meticulously planned and highly complex precision air-land operation" carried out Saturday between midnight and 4 a.m. in Metele, located in Borno State in northeast Nigeria.

U.S. Africa Command, or AFRICOM, placed the strike in northeastern Nigeria, with Nigerian army communications pointing specifically to the Metele region.

Despite the tactical success, the current ISIS "caliph," or overall leader, remains on the run, according to reports.

Al-Qurashi was "named following his predecessor’s death in Syria," Mohammed claimed.

"He is deliberately faceless, with analysts describing this line of leaders as the ‘caliphs of the shadows,’" Mohammed said, noting al-Qurashi assumed leadership after Turkish authorities killed his predecessor in 2023.

While al-Qurashi’s exact location is unknown, reports indicate he traveled from Syria or Iraq through Yemen to Somalia’s semi-autonomous Puntland region.

"This is where the financial hub also sits, meaning the entire center of gravity of the organization — leadership, finance, operational direction — has been quietly relocating to Africa for years," Mohammed said.

Data from the Armed Conflict Location & Event Data Project confirms this regional shift, showing more than two-thirds of all Islamic State global activity now takes place in Africa.

"Africa has transitioned from a peripheral theater to the operational and financial center of global ISIS activity," Mohammed explained. "Africa is no longer a peripheral theater. It is the main one. Funding is overwhelmingly local and extractive — taxation, ransom, smuggling — which is precisely why these networks are so resilient."

"Al-Minuki, for example, rose through ISWAP and operated across the Lake Chad Basin and into the wider Sahel," he noted.

"Still, staking out al-Minuki is the most significant blow to ISIS’ global leadership architecture since the al-Baghdadi raid in 2019, executed in the theater that has quietly become the group’s beating heart," Mohammed said before adding the strike was "not a one-off kinetic moment."

President Donald Trump announced late Friday that U.S. and Nigerian forces carried out an operation that killed a global ISIS leader.

Trump identified the terrorist as Abu-Bilal al-Minuki, whom he described as ISIS’s second-in-command globally.

"Tonight, at my direction, brave American forces and the Armed Forces of Nigeria flawlessly executed a meticulously planned and very complex mission to eliminate the most active terrorist in the world from the battlefield," Trump wrote in a post on Truth Social.

"Abu-Bilal al-Minuki, second in command of ISIS globally, thought he could hide in Africa, but little did he know we had sources who kept us informed on what he was doing," Trump continued. "He will no longer terrorize the people of Africa, or help plan operations to target Americans."

Trump also thanked the Nigerian government for its cooperation in the mission.

"With his removal, ISIS’s global operation is greatly diminished," he added.

In a Saturday morning X post, Secretary of War Pete Hegseth confirmed U.S. forces, in coordination with the Armed Forces of Nigeria, killed al-Minuki and other ISIS leaders and provided more details about al-Minuki's role within ISIS.

"Abu-Bilal al-Minuki was the senior ISIS General Directorate of Provinces Emir — the number two for ISIS globally — responsible for overseeing the planning of attacks, directing hostage-taking and managing financial operations," Hegseth wrote. "The removal of him and other ISIS personnel makes Americans safer by further degrading ISIS’s ability to plan and carry out attacks that threaten the U.S. homeland, American citizens, and innocent civilians. "

"Operations like last night’s demonstrate the exceptional lethality, patience and skill of U.S. forces, amplified alongside willing and capable partners, to address shared threats," Hegseth wrote. "This should serve as a reminder that we will hunt down those who wish to harm Americans or innocent Christians, wherever they are."

Hegseth said U.S. Africa Command carried out the "precise operation to remove this terrorist" at Trump's direction and in conjunction with Nigeria's president. 

The secretary reiterated how Trump in November "declared to the world that we will help protect Christians in Nigeria and instructed the Department of War to prepare for action."

"So, for months, we hunted this top ISIS leader in Nigeria who was killing Christians, and we killed him — and his entire posse," Hegseth wrote.

Fox News Digital has reached out to the White House for comment.

United States Africa Command (AFRICOM) confirmed the ISIS strikes in a Saturday statement.

"At the direction of the President of the United States and the Secretary of War, and in coordination with the Government of Nigeria, U.S. Africa Command conducted an operation against ISIS in Northeastern Nigeria on May 16, 2026," the statement read. "The command’s initial assessment is that multiple terrorists, to include Abu-Bilal al-Minuki, the director of global operations for ISIS, as well as other senior ISIS leaders, were killed during this operation. No U.S. service members were harmed."

"As President Trump shared last night, AFRICOM in coordination with the Armed Forces of Nigeria, bravely and valiantly conducted a successful mission that resulted in the elimination of Abu-Bilal al-Minuki, and multiple other ISIS leaders," AFRICOM commander U.S. Air Force Gen. Dagvin Anderson said in a statement.

"This operation underscores the exceptional value of the U.S.-Nigeria partnership and was made possible through the cooperation and coordination of our forces in recent months. Make no mistake, our two nations will relentlessly pursue and neutralize terrorist threats and are committed to protecting our people and interests," Anderson said.

Al-Minuki, the statement added, provided "strategic guidance to the ISIS global network on media and financial operations as well as the development and manufacturing of weapons, explosives, and drones." 

Al-Minuki was "the most active terrorist in the world and has a significant history of involvement in planning attacks and directing hostage taking," AFRICOM wrote.

The announcement comes after U.S. Central Command (CENTCOM) said it carried out multiple strikes against more than 30 ISIS targets in Syria in February as part of a joint military effort to "sustain relentless military pressure on remnants from the terrorist network."

CENTCOM said U.S. forces struck ISIS infrastructure and weapons-storage targets using fixed-wing, rotary-wing and unmanned aircraft.

Trump told reporters on Jan. 27 that he had a "great conversation" with Syrian President Ahmed al-Sharaa.

"All of the things having to do with Syria in that area are working out very, very well," he said at the time. "So, we are very happy about it."

CENTCOM announced in February that more than 50 ISIS terrorists had been killed or captured and more than 100 ISIS infrastructure targets struck during two months of targeted operations in Syria.

The U.S. launched Operation Hawkeye Strike in response to an ISIS ambush that killed two U.S. service members and an American interpreter Dec. 13, 2025, in Palmyra, Syria.
