LAGOS, Nigeria (AP) -- Authorities say two people were wounded after a bomb exploded in a city in northern Nigeria.
Bauchi state police spokesman Mohammed Barau said Saturday that the explosion happened around 7 p.m. Friday in the state capital of Bauchi. Barau said explosive experts visited the scene of the blast inside the city and have begun an investigation.
Barau said police continued to investigate the blast, but had no idea of the motive behind the attack.
The attack comes after more than 100 people died in bombings and gunfights carried out Nov. 4 in northeast Nigeria. A radical Muslim sect known as Boko Haram claimed responsibility.
Boko Haram has been carrying out a string of targeted assassinations for more than a year by gunmen on motorcycles and carrying out bombings in the north.
