Witnesses say 34 persons have been killed by a teenage girl suicide bomber at a crowded market in the northeastern Nigerian city of Maiduguri.

Musa Danbaba, a member of a civilian protection militia, said the blast by a female teenager occurred in the market near the Old Elkanemi Cinema in the late afternoon. He said the 34 bodies were counted and many more were wounded.

No group immediately claimed responsibility for the bombing, but it bears the hallmarks of Nigeria's Islamic extremist group, Boko Haram.

The Maiduguri market is where suicide bombers on Saturday detonated explosives that killed 54 people.
