The United States and the United Kingdom on Monday commended the Federal Government and its security agencies for the successful arrest of two senior leaders of the terrorist group Jama’atu Ansarul Muslimina fi-Biladis Sudan, also known as Ansaru.
The arrests were confirmed by the National Security Adviser, Nuhu Ribadu, who described the development as the result of a “high-risk, intelligence-led, counter-terrorism operation” carried out between May and July 2025.
The individuals apprehended include Mahmud Usman, identified as the self-styled Emir of Ansaru.
According to the NSA, Usman served as the coordinator of numerous terrorist sleeper cells across the country and was behind several high-profile kidnappings and armed robberies used to fund the group’s activities.
His deputy, Mahmud al-Nigeri, led the group’s “Mahmudawa” cell, which was said to be active around the Kainji National Park area, spanning Niger and Kwara states and extending into neighboring Benin Republic.
Following the arrests, the US Embassy in Nigeria issued a statement via its official X handle, describing the operation as a major step in Nigeria’s ongoing efforts to combat terrorism and extremism.
The embassy praised the Nigerian security forces and described the arrests as a significant achievement.
The post read, “We commend the Nigerian government and security forces on the successful arrest of wanted #Ansaru leaders, Mahmud Muhammad Usman (aka Abu Bara’a) and Mahmud al-Nigeri (aka Mallam Mamuda).
“This is a significant forward in Nigeria’s fight against terrorism and extremism.”
Similarly, the British High Commissioner to Nigeria, Richard Montgomery, also took to X to describe the operation as an extraordinary and very significant success, commending the security agencies and their leadership under the NSA.
“An extraordinary & very significant success. A major step forward in the fight against terrorism. Congratulations to the security agencies & officers involved under the leadership of NSA Ribadu,” Montgomery noted.
According to the Federal Government, the arrested terrorist leaders, who were internationally wanted, are now in custody.
Ansaru, formed in January 2012 as a splinter group from Boko Haram, presented itself as a more “humane” alternative but quickly turned to violent attacks on civilians, security forces, and infrastructure. The group aligned ideologically with global jihadist movements, particularly Al-Qaeda in the Islamic Maghreb, and established a presence in urban cells and forest enclaves, especially around Kainji National Park.
Two key figures from Ansaru, long on Nigeria’s most-wanted list, led several major attacks, including the 2022 Kuje prison break, a uranium facility attack, and high-profile kidnappings such as that of French engineer Francis Collomp and traditional leader Alhaji Musa Uba. They also had strong ties with terrorist groups across the Maghreb. (Punch)
