Nigeria's government is negotiating the release of another 83 of the schoolgirls taken in a mass abduction two-and-a-half years ago, but more than 100 others appear unwilling to leave their Boko Haram captors, a community leader says.
The unwilling girls might have been radicalised by the Islamic extremists or are ashamed to return home because they were forced to marry and have babies, chairman Pogu Bitrus of the Chibok Development Association said.
He told the Associated Press the 21 Chibok girls freed last week in the first negotiated release between Nigeria's government and Boko Haram should be educated abroad because they will probably face stigma in Nigeria.
The girls and their parents were reunited on Sunday and were expected to meet Nigerian President Muhammadu Buhari, Bitrus said.
Buhari said on Monday his government was prepared to talk with Boko Haram as long as the extremists agreed to involve organisations such as the International Committee of the Red Cross, which was an intermediary in last week's release.
About 276 schoolgirls were kidnapped from a school in northeastern Chibok in April 2014.
Dozens escaped early on and at least half a dozen have died in captivity, according to the freed girls.
Those who escaped on their own have left Chibok because, even though they were held only a few hours, they were labelled "Boko Haram wives" and taunted, he said.
At least 20 of the girls were being educated in the US.
All Nigerian institutions and the freed girls' communities and families must "stand strong" to "protect them from stigma, ostracisation and rejection", the UN special rapporteurs on the sale of children, on slavery and on the right to health said in a statement.
One Chibok girl, Amina Ali Nkeki, escaped in May.
Chibok Parents Association chairman Yakubu Nkeki said the young woman had been reunited with her freed classmates, all of whom were being treated at a hospital in Abuja, Nigeria's capital.
