The trial of the Nigerian separatist leader Nnamdi Kanu is expected to resume in Abuja on Thursday.
Mr Kanu – the leader of the Indigenous People of Biafra (a pro-Biafra separatist group) – is charged with terrorism and treason.
He’s also charged with running an illegal company and publishing defamatory materials.
Tension rose in July when the authorities failed to present him before the court for trial.
Mr Kanu was first arrested in 2015, but he fled Nigeria two years later after the Nigerian army invaded his home. He was rearrested in June this year.
His lawyers say he’s been held in solitary confinement, in the custody of the Nigerian secret police.
He faces life imprisonment if found guilty.
