The highest court in Nigeria will soon make a decision about whether to release separatist leader Nnamdi Kanu.
Mr Kanu leads a group called the Indigenous People of Biafra (Ipob) that wants to make a new country in south-eastern Nigeria.
He wants to be let out of jail because he believes there is no reason for the government to keep him there. The government wants to keep him in jail for a longer time and is asking the court to agree.
Mr Kanu was arrested in 2015 and then ran away from Nigeria in 2017 while he was waiting for his trial to start.
He has been in jail since 2021, when he was brought back from Kenya to be charged with terrorism.
Last year in October, a court said Mr. Kanu should be released because there were legal problems with how he was sent to jail.
The government tried to stop the separatist leader from being released because they were afraid that he might run away and cause trouble.
Some leaders from the south-eastern part of Nigeria want him to be set free.
