FG Arrests Kuje Prison Break Masterminds

The Federal Government on Saturday announced the arrest of two top leaders of Jama’atu Ansarul Muslimina fi-Biladis Sudan, an Al-Qaeda affiliate in Nigeria, following a months-long counter-terrorism operation.

The National Security Adviser, Nuhu Ribadu, disclosed this at a press briefing held at the Office of the National Security Adviser in Abuja.

Ribadu said the intelligence-led operation was carried out between May and July 2025 in collaboration with security and intelligence agencies.

Those arrested are Mahmud Muhammad Usman, also known as Abu Bara’a, Abbas or Mukhtar, identified as the self-styled Emir of Ansaru, and his deputy, Mahmud al-Nigeri, also known as Mallam Mamuda.

According to Ribadu, Abu Bara coordinated terrorist sleeper cells across Nigeria and masterminded high-profile kidnappings and armed robberies to finance terrorism.

He added that his deputy, Mamuda, led the “Mahmudawa” cell around Kainji National Park and trained in Libya between 2013 and 2015 under foreign jihadist instructors.

Ribadu said, “The targeted operation, which was conducted between May and July 2025, led to the capture of two top ANSARU leaders who have been responsible for masterminding several terrorist attacks against Nigeria over the past years. The first is Mahmud Muhammad Usman (aka Abu Bara’a/Abbas/Mukhtar), the self-styled Emir of ANSARU.

“He is the coordinator of various terrorist sleeper cells across Nigeria. He is also the mastermind of several high-profile kidnappings and armed robberies used to finance terrorism over the years.

“The second is Mahmud al-Nigeri (aka Mallam Mamuda), Abu Bara’s proclaimed Chief of Staff and Deputy. He is the leader of the so-called “Mahmudawa” cell hiding out in and around the Kainji National Park, straddling Niger and Kwara States up to the Benin Republic. Mamuda trained in Libya between 2013 and 2015 under foreign jihadist instructors from Egypt, Tunisia, and Algeria, specialising in weapons handling and IED fabrication.”
