Nigeria has achieved a significant milestone in its fight against terrorism by apprehending two high-ranking leaders of the Al-Qaeda-affiliated Ansaru group, officials confirmed on Saturday.
During a press conference in Abuja, National Security Adviser (NSA) Nuhu Ribadu revealed that a meticulously planned, intelligence-led operation culminated in the capture of Mahmud Muhammad Usman, widely known as Abu Bara’a, and Mahmud al-Nigeri, also referred to as Mallam Mamuda.

Abu Bara’a, recognized as the “Emir of Ansaru,” orchestrated the group’s covert cells nationwide and was the mastermind behind numerous abductions and terror financing schemes. His deputy, Mamuda, led the “Mahmudawa” faction, operating primarily around Kainji National Park, and had received training in Libya from foreign jihadist mentors.
“These two men have been on Nigeria’s most-wanted list for years and are also internationally sought terrorists,” Mr Ribadu said. “Their capture marks one of the most decisive blows against Ansaru since its emergence in 2012.”
Ansaru, officially named Jama’atu Ansarul Muslimina fi-Biladis Sudan, splintered from Boko Haram in 2012 and gained infamy for targeting civilians, security personnel, and critical infrastructure. Pledging loyalty to Al-Qaeda in the Islamic Maghreb (AQIM), the group was behind major incidents, including the 2022 Kuje prison break in Abuja, the 2013 kidnapping of French engineer Francis Collomp in Katsina, the 2019 abduction of Alhaji Musa Umar Uba, Magajin Garin Daura, the kidnapping of the Emir of Wawa, attacks on a Niger uranium facility, and other cross-border operations.
According to Mr Ribadu, the arrests, which occurred between May and July 2025, have effectively disrupted Ansaru’s leadership structure. Recovered materials and digital evidence are currently under forensic examination, expected to provide further insights into the group’s regional networks across Nigeria and the Sahel.
Ribadu commended President Bola Tinubu for his strategic guidance and lauded the collaborative efforts of the military, intelligence agencies, and other partners in executing the operation.
“The fall of Ansaru’s leadership signals the beginning of the end of impunity for terrorist leaders in Nigeria,” the NSA declared. “We will continue to pursue extremists with precision, resolve, and unwavering determination.”
Officials called on citizens to stay alert and share actionable intelligence with security agencies, emphasizing that national security is a collective responsibility.
