Twin suicide bombers linked to the Boko Haram sect attacked a mosque in Gwoza, Borno state, on Sunday, killing a 12-year-old child and leaving many people injured.
A security source, said the suicide bombers forced their way into the mosque while prayer was ongoing.
The source said before some persons in the neighbourhood raised the alarm, the attackers had already gained entry into the mosque.
The incident happened around Guduf Nagadiyo at Bulabaulin in Gwoza.
Soldiers from 192 battalion of the Nigerian Army later cordoned off the mosque.
A resident said the suicide bombers might have infiltrated the town during a wedding which held at the palace of the emir of Gwoza on Saturday.
