The Federal High Court in Abuja has sentenced two senior commanders of the Ansaru terrorist group to life imprisonment after they pleaded guilty to multiple terrorism-related charges brought against them by the Federal Government.
The convicts, Mahmud Usman, also known as Isah Adam, and Abubakar Abba, alias Abu Bara, admitted their involvement in terrorism, terrorism financing and other serious crimes before Justice Emeka Nwite, who convicted and sentenced them on Monday.
The prosecution was conducted by the Department of State Services (DSS) on behalf of the Federal Government.
Justice Nwite sentenced both men to life imprisonment on counts 30 and 31 of the 32-count charge filed against them.
In addition, the court imposed 20 years’ imprisonment on each of the remaining counts. The judge directed that all the prison terms should take effect from the dates of their arrest.
The judgment marks another major conviction in Nigeria’s ongoing efforts to prosecute suspected terrorists and dismantle extremist networks operating within the country and across West Africa.
The DSS arrested the two men in separate operations carried out between May and July 2025 after months of intelligence gathering and surveillance.
According to the Federal Government, both men occupied leadership positions within Ansaru, a terrorist organisation affiliated with Al-Qaeda.
The government accused them of participating in several terrorist activities, including financing terrorist operations, coordinating attacks and supporting violent extremist groups operating in Nigeria and neighbouring countries.
The 32-count charge also accused the convicts of kidnapping victims for ransom, engaging in illegal mining to generate funds for terrorist activities and manufacturing improvised explosive devices (IEDs).
Prosecutors further alleged that the two men coordinated sleeper cells and maintained operational links with terrorist organisations across the Sahel and Maghreb regions of Africa.
Security agencies told the court that these connections enabled the movement of funds, weapons and personnel across borders, strengthening terrorist networks in the region.
The Federal Government argued that the activities of the two men posed a serious threat to Nigeria’s national security and justified the severe punishment provided under the country’s anti-terrorism laws.
Court records showed that Mahmud Usman had earlier pleaded guilty to one count of illegal mining carried out for the purpose of financing terrorism and procuring weapons for terrorist operations.
Following that admission, Justice Nwite sentenced him to 15 years’ imprisonment on the count while the trial continued on the remaining charges.
At that stage, Usman had denied the other 31 counts brought against him.
His co-defendant, Abubakar Abba, initially pleaded not guilty to all 32 counts when the charges were first read to him.
However, during the last hearing on July 9, 2026, Abba informed the court that he intended to change his plea.
Although he briefly expressed reservations during the proceedings, he eventually admitted guilt to all the charges filed against him.
Usman also changed his position and pleaded guilty to the remaining counts.
Their decision to admit guilt meant that the court no longer needed to conduct a full trial or hear additional witnesses before delivering judgment.
Justice Nwite subsequently convicted both men on all the charges before pronouncing sentence in accordance with the provisions of the Terrorism (Prevention and Prohibition) Act and other relevant laws.
The convictions are seen as another important step in Nigeria’s efforts to strengthen the prosecution of terrorism cases.
In recent years, security agencies have increased intelligence operations targeting terrorist financiers, arms suppliers and leaders of extremist organisations operating in different parts of the country.
The Federal Government has repeatedly stated that military operations alone cannot end terrorism and that successful prosecution of suspects remains essential to weakening terrorist groups.
Ansaru, formally known as Jama’atu Ansarul Muslimina Fi Biladis Sudan, emerged more than a decade ago after breaking away from Boko Haram.
Unlike Boko Haram, which largely focuses its operations within Nigeria, Ansaru has maintained ideological and operational ties with Al-Qaeda and has been linked to extremist groups across the Sahel region.
The group has been accused of carrying out attacks on security personnel, kidnapping foreign nationals, attacking communities and supporting cross-border terrorist activities.
Although its activities reduced for some years following military offensives, security agencies have continued to warn that the group remains active in parts of northern Nigeria.
Authorities have also expressed concern over growing cooperation among terrorist organisations operating across the Sahel, where political instability and weak border controls have created opportunities for extremist groups to expand.
The Federal Government has therefore intensified efforts to cut off sources of terrorist financing.
One area of concern has been illegal mining, which security agencies say has increasingly become a source of funding for armed groups.
Authorities have repeatedly warned that proceeds from illegal mining have been used to purchase weapons, recruit fighters and finance terrorist attacks in parts of the country.
Kidnapping for ransom has also become another major source of income for terrorist and criminal groups, with victims often held for weeks or months before large sums are paid for their release.
The government has introduced stricter laws against terrorism financing, money laundering and the payment of ransom in an effort to reduce the financial strength of violent groups.
The DSS has continued to work with the military, the Nigeria Police Force and other security agencies to identify, arrest and prosecute individuals linked to terrorism.
Several terrorism cases are currently pending before Nigerian courts as the government continues its efforts to ensure that suspects are brought to justice.
With the life sentences handed down by the Federal High Court, Mahmud Usman and Abubakar Abba are expected to remain in custody as the government continues its broader campaign to dismantle terrorist networks, disrupt their funding sources and improve security across the country.
