Boko Haram has released a video purporting to show some of the Chibok schoolgirls still in captivity.

“In the video, a girl dressed in a full niqab [Islamic dress] appeals to her parents to embrace Islam,” the BBC’s Stephanie Hegarty reports.

“Dressed in a blue and white niqab, the young woman’s face is concealed. Only her eyes can be seen as she recites prayers in Arabic and then switches to [the] Hausa language.”

The girl says the video is meant for her parents and asks them to convert to Islam. She adds that she doesn’t want to return home because the girls are “well-treated”.

“It’s unclear whether she’s being forced to speak,” Hegarty says.

“She’s surrounded by about ten other young women, most of whose faces can be seen. Their identities have yet to be confirmed.

“One of them is holding a small baby and, beside her, a little girl of about two years is playing.”

On 4 January, the Nigerian Army announced it had rescued another of the schoolgirls kidnapped in Chibok four years ago.

The girl, identified as Salomi Pogu, was found in Pulka, in the north-eastern state of Borno, with another girl, aged 14, who was carrying a baby with her.
