US and Nigerian Forces Kill Senior Islamic State Figure in Northeast Nigeria

President Donald Trump announced the killing of Abubakar Mainok, also known as Abu-Bilal al-Mainuki or Abu Bilal al-Minouki or al-Minuki, in a joint operation by US special forces and Nigerian troops carried out in the North-east of Nigeria on May 16, 2026.

Trump described the operation as a meticulously planned and very complex mission. US intelligence tracked Mainok despite his attempts to remain hidden on the African continent.

The president stated that the operation removed the most active terrorist in the world from the battlefield. "He thought he could hide in Africa," Trump said, according to the statement posted by the White House on X. " Abubakar Mainok was described as the Islamic State's global second-in-command and one of the most active global ISIS operatives.

Mr Mainok, according to documents obtained from US registers, was specially designated as a "global terrorist" in 2023. One of the documents traced his origin to Mainok, a town in Kaga Local Government Area of Borno State. A 2023 report by the Jamestown Foundation identified Abubakar Mainok as a senior Islamic State figure coordinating activities between ISWAP and IS-Sahel networks through the group's al-Furqan office.

AllAfrica reported that security analysts have long linked him to the Islamic State's operations in West Africa and the Sahel. The announcement occurred on May 16, 2026. Sources familiar with the situation confirmed the incident to Premium Times, with one source stating that Mr Mainok was killed in the North-east.

Although the Nigerian government has not issued an official statement about the mission, the cooperation marks a significant milestone in recent counterterrorism collaboration between the United States and Nigeria. Approximately 200 US troops were deployed to Nigeria following a diplomatic faceoff between Washington and Abuja.

The diplomatic faceoff concerned what President Trump described as Christian genocide.

AllAfrica reported that the deployment followed renewed warnings from US security agencies that militant organizations continue seeking to reorganize through regional affiliates operating in Africa. The operation comes as Washington continues expanding counterterrorism cooperation with African partners amid growing concerns over extremist activity across parts of the Sahel and West Africa.

ISIS-linked groups have increased attacks in several African countries in recent years, exploiting weak state control, regional instability and ongoing conflicts to expand their operations.

US military officials have repeatedly warned that Africa is becoming an increasingly important front in the global fight against extremist organizations following the weakening of ISIS networks in Iraq and Syria.
