A significant controversy has erupted following the reported killing of Abu-Bilal Al-Manuki, a senior leader of the Islamic State West Africa Province (ISWAP) and the Islamic State (ISIS), in a joint operation by Nigerian and United States forces in May 2026. Public skepticism was immediately raised as the Nigerian military had previously announced the death of a terrorist bearing the same name in 2024, leading to questions about the accuracy of intelligence and counterterrorism announcements.

The latest operation, which President Bola Tinubu and US President Donald Trump both confirmed, was described by Trump as a "meticulously planned and very complex mission." Al-Manuki, also known as Abu-Mainok or Abu-Bilal Al-Minuki, had been specially designated as a "global terrorist" in 2023. Operational details provided by the Nigerian Army, through its Operation Hadin Kai spokesperson Sani Uba (also referred to as Major General Samaila Uba of Defence Headquarters), indicated that the mission involved troops from Operation Hadin Kai and the United States Africa Command (AFRICOM). It was a "precision air-land operation" carried out in Metele, a border community in Borno State near Niger Republic, within the Lake Chad Basin area. The operation, which commenced around 12:01 a.m. and concluded about 4:00 a.m. on Saturday, May 16, 2026, followed prolonged intelligence gathering, including legal intercept operations and sustained reconnaissance that reportedly began in December 2025. Military sources confirmed that Al-Manuki and his international terrorist cell had established a concealed and fortified enclave in Metele. Coordinated air and ground strikes were launched, with Special Forces deployed to block escape routes. The operation was executed with "zero casualties or loss of assets" and was hailed as "the single most consequential counter-terrorism outcome in the North East Theatre since the inception of Operation Hadin Kai."

The root of the controversy lies in an April 2024 announcement by the Nigerian Defence Headquarters, then led by Major General Edward Buba, which listed Abu Bilal Minuki, also known as Abubakar Mainok, among 11 notorious terrorist commanders killed by Nigerian troops between January and March 2024. At that time, he was identified as the "Head of IS-Al Furqan Province" and linked to operations around the Birnin Gwari forest axis in Kaduna State and along the Abuja-Kaduna highway, with his elimination reported on February 21, 2024.

President Tinubu's spokesperson, Bayo Onanuga, sought to clarify the confusion, attributing the 2024 report to "inaccurate information" and a "case of mistaken identity or misattribution in the fog of sustained counterinsurgency operations." Onanuga stated that intelligence now confirms the Birnin Gwari theatre was never within Al-Manuki’s established operational sphere, negating the accuracy of the earlier assessment. For the 2026 killing, security and military authorities maintain a "far higher level of confidence," stating they are "100 per cent certain." This latest operation, according to Onanuga, resulted from prolonged Intelligence, Surveillance, and Reconnaissance (ISR) efforts, supported by communications monitoring, phone intercepts, digital surveillance, and human intelligence gathered over months across key locations in northern Nigeria, including Abuja and Maiduguri. Efforts initially focused on capturing Al-Manuki alive. Onanuga emphasized that multiple layers of verification were applied before authorization of the final kinetic action, making this operation distinct and unambiguous. He cautioned against comparing it to past cases of wrongly declared deaths, such as that of Boko Haram leader Abubakar Shekau.

The Defence Headquarters, in a statement by Major General Samaila Uba, further explained that the use of similar or identical names, aliases, and nom de guerres is common among ISWAP and Boko Haram terrorists, deliberately obscuring identities and complicating intelligence gathering. Despite these similarities, the military insisted that the individual killed on May 16, 2026, was conclusively identified through both human intelligence and technical surveillance as a senior global operative within the Islamic State network, with direct links to international terrorist coordination, financing, and militant activities across the Sahel region.

Al-Manuki's profile within extremist networks is significant. He was described as a central operational figure within ISIS, potentially elevated to the position of Head of the General Directorate of States by February 2026, making him the second most senior leader within the ISIS global hierarchy. He was responsible for coordinating international funding and operational directives to terrorist cells across the Sahel and the Lake Chad Islands, directing ISIS affiliates on media propaganda, economic warfare, and the development of weapons, explosives, and drone technology. His origin was traced to Mainok, a town in Kaga Local Government Area of Borno State. Before joining ISIS, he was a prominent Boko Haram commander and pledged allegiance to ISIS in 2015, becoming deeply involved in operations across West Africa and the Sahel. He was also linked to the infamous mass kidnapping of over 100 schoolgirls in Dapchi, Yobe State, in 2018, and facilitated the movement of fighters into Libya between 2015 and early 2016.

Reactions to the killing were varied. Human rights lawyer Femi Falana criticized President Tinubu for relying on President Trump's claims instead of obtaining accurate briefings from the Nigerian Defence Headquarters, urging the government to strengthen Nigeria’s military capacity rather than depending on foreign validation. Controversial Islamic cleric Sheikh Ahmad Gumi condemned the involvement of those with "hands stained with the blood of innocent men, women, and children" while affirming that combating terrorism is a religious obligation. Despite the controversy, military authorities and the presidency maintain that the operation represents a validated, intelligence-driven success against a senior figure of the Islamic State network, underscoring the deepening security cooperation between Nigeria and the United States in the global fight against terrorism.
