They were kidnapped last month in the town of Damboa, south of Borno state’s capital Maiduguri. This is the same state where nearly 300 schoolgirls were taken in mid-April.
The women and girls reportedly escaped while Boko Haram militants left to attack a Nigerian military base.
More than 200 schoolgirls are still being held by Boko Haram, along with a couple dozen boys.
Last week, the Nigerian military announced it had captured several suspects in the kidnappings, including a businessman believed to be in charge of an intelligence network for Boko Haram.
