Nnamdi Kanu, leader of the Indigenous People of Biafra (IPOB), has been re-arraigned at a federal high court in Abuja on terrorism charges.
The federal government recently amended the charges against him raising them to seven counts as against the five counts he was previously answering to, bordering on treasonable felony and terrorism.
The court session on Thursday commenced at 10 am.
When the charges were read to him, the IPOB leader pleaded not guilty.
In June, Kanu was arrested abroad and brought to Nigeria after he jumped bail and fled to the UK in 2017.
He has been in the custody of the Department of State Services (DSS) since his arrest.
