In a thunderous breakthrough against terrorism, Nigeria’s security forces have netted two of the most dreaded terror masterminds in a high-risk operation hailed as one of the country’s biggest counter-terrorism victories.
National Security Adviser (NSA), Nuhu Ribadu, revealed that the dramatic sting led to the arrest of Mahmud Muhammad Usman a.k.a. Abu Bara’a/Abbas/Mukhtar, the self-proclaimed Emir of Ansaru, and his ruthless deputy, Mahmud al-Nigeri a.k.a. Mallam Mamuda.
“These men were international fugitives, long on our radar. Today, I am glad to announce they are in our custody,” Ribadu declared triumphantly.
The Terror Lords of Ansaru
Usman, described as the shadowy coordinator of Ansaru sleeper cells across Nigeria, is accused of masterminding high-profile kidnappings, armed robberies, and countless bloody assaults against civilians and security forces.
His partner-in-crime, al-Nigeri, infamously commanded the deadly “Mahmudawa” cell entrenched in the Kainji National Park axis stretching from Niger and Kwara States to the Benin Republic. A Libyan-trained jihadist, he specialised in IED fabrication and guerrilla warfare tactics after training with North African extremists.
Ansaru: Boko Haram’s Ruthless Offshoot
Formed in 2012 as a splinter from Boko Haram, Ansaru once pretended to be a “humane alternative.” But that façade quickly crumbled as the group unleashed a reign of terror — from ambushing security forces to staging high-profile kidnappings and aligning itself openly with Al-Qaeda in the Islamic Maghreb (AQIM).
Over the years, Ansaru embedded itself deep into Nigeria’s forests and cities, running sleeper cells and expanding its tentacles into the wider Sahel.
Trail of Blood and Infamy
The two captured kingpins are said to be architects of some of Nigeria’s most shocking terror strikes:
The 2022 Kuje Prison Break.
The assault on Niger’s uranium facility.
The infamous 2013 kidnapping of French engineer Francis Collomp in Katsina.
The brazen 2019 abduction of Alhaji Musa Umar Uba, Magajin Garin Daura.
The kidnapping of the Emir of Wawa.
“These men had ties with terror networks in Mali, Niger, and Burkina Faso. Their arrest cripples a critical artery of international jihadism,” Ribadu emphasised.
Nigeria Roars Back
The NSA confirmed that the painstaking operation — conducted between May and July 2025 — was intelligence-led and executed with surgical precision.
Minister of Information, Mohammed Idris, called on Nigerians to rally behind the government:
“This is a turning point. We must not let terrorists feed off publicity. The real story is that Nigeria is winning.”
With these arrests, security analysts say Ansaru has suffered its biggest blow in a decade — a strike that could tilt the balance in Nigeria’s long war against terror.
