Boko Haram has allegedly abducted dozens more girls in northeast Nigeria, damaging hopes of a ceasefire agreement with the Government.
The latest kidnappings took place during a large-scale assault by the insurgent group on two villages in the lawless Adamawa state, according to residents.
The attacks on the villages of Waga Mangoro and Garta happened last Saturday - a day after the Nigerian Government claimed to have brokered a truce with the group.
Government officials said the truce was expected to lead to the freeing of more than 200 schoolgirls kidnapped by Boko Haram from a school in the town of Chibok, also in northeast Nigeria, in April. But doubts have since been expressed about the credibility of the intermediary who was said to have brokered the deal.
The latest abduction is one of a series of further mass kidnappings that the group has carried out as part of its terror campaign, in which it has also massacred hundreds of people at a time.
