Some 190 Nigerian schoolgirls remain missing after being abducted last week, their head teacher has told the BBC – far more than the official figure.
Asabe Kwambura said the parents of 230 girls had reported them missing but 40 had managed to escape.
Earlier, a local state governor said that about 77 of the teenagers had not been accounted for.
Islamist group Boko Haram is suspected to be behind the kidnapping but has not issued any statement.
Some 1,500 people are believed to have been killed in attacks blamed on Boko Haram this year alone. . .
