Boko Haram released a new video on claiming to show the missing Nigerian schoolgirls, alleging they had converted to Islam and would not be released until all militant prisoners were freed.  A total of 276 girls were abducted on April 14 from the northeastern town of Chibok, in Borno state, which has a sizeable Christian community. Some 223 are still missing. AFP PHOTO / BOKO HARAM

A female bomber blew herself up Sunday in northeast Nigeria, killing at least 15 people and injuring 46 others, according to the head of the Nigeria’s National Emergency Management Agency.

The woman lived in the area where the attack happened in the city of Damaturu in Yobe state, residents Kulo Fannami and Halilu Grema told CNN. The bomb went off at a busy market, witnesses and medical officials said.

No one has claimed responsibility for the attack.
