At least 30 people have been killed and some 80 more wounded in a bombing attack in Nigeria’s northeastern state of Borno.

According to a member of the local civilian defense forces, the attack was carried out in the town of Mandarari, located some 25 kilometers from the state capital Maiduguri.

“Three female bombers triggered their explosives outside of the IDP (internally displaced persons) camp... killing 28 people and wounding 82 others," said Baba Kura. “People were trying to close their shops when two other female bombers triggered their explosives, causing most of the casualties," he added.

A local medical source said that following the blasts a "huge number" of people were admitted to the Maiduguri hospital. Two of the wounded succumbed to their injuries in the hospital.

No individual or group has claimed responsibility for the attack yet, but such incidents are usually blamed on the Takfiri Boko Haram terrorist group, which is particularly active in the country’s northeast region.
