Security forces or the police should be used to free more than 230 girls kidnapped by suspected Boko Haram militants in Nigeria, chair of the Africa Progress Panel Kofi Annan has said.

In a video that emerged earlier in the week, which the former UN chief described as "atrocious", the leader of the Islamist group threatened to "sell" the girls seized from their school on 14 April.

Police have also said that eight more girls between the ages of 12 and 15 were kidnapped in north eastern Nigeria on Sunday night.
