At least 20 people have been jailed in Nigeria for being members of the Islamist militant group Boko Haram.
The accused were sentenced to jail terms of between three and 15 years as part of the ongoing mass trials of more than 1,000 suspects at a military facility in the north-central town of Kainji.
Among the convicted was a disabled man found guilty of participating in the abduction of more than 200 schoolgirls in the north-eastern town of Chibok in 2014.
He has been sentenced to 15 years in prison, the first time someone has been jailed in connection with the Chibok abductions.
Sources at the courts told the BBC that a further 700 suspects are due to stand trial this week.
The Nigerian authorities say there are more than 6,000 Boko Haram suspects being detained across the country.
In October, 45 people were sentenced to between three and 31 years in prison for being members of the militant group.
