Nigeria has launched one of the largest terrorism prosecutions in its history, beginning the mass trial of more than 500 suspected militants at the Federal High Court in Abuja. The suspects, many held in custody for years without charge, face terrorism-related offences including aiding and abetting Islamist insurgents, providing material support to militant groups, and participating directly in attacks across northern Nigeria.
The opening of the trial marked a significant moment for a country where critics have long complained that suspects are routinely arrested but rarely brought to justice. Attorney General Lateef Fagbemi said the scale of the prosecution demonstrated the federal government’s commitment to ensuring that those involved in terrorism face the full weight of the law.
Five of the accused have already been convicted and sentenced. They pleaded guilty to charges of supplying food, livestock, and information to Boko Haram fighters — offences carrying sentences of between seven and twenty years.
The trial is being conducted simultaneously across 13 courtrooms, with ten federal high court judges presiding. International observers, including representatives of human rights organisations and the Nigerian Bar Association, have been given access — a notable departure from the opacity that has characterised many previous security-related prosecutions.
Security analyst Bashir Galma, a retired army major, described the prosecution as a positive development and a significant milestone, though he warned that the passage of time since many suspects were first detained was likely to complicate the prosecution’s task.
The trial opens against a backdrop of continued violence. Gunmen killed at least 20 people in Niger State days before proceedings began, highlighting overlapping threats in northwestern Nigeria where kidnapping gangs operate alongside Islamist militants.
