KADUNA, Nigeria - An explosion near a popular nightspot in the northern Nigerian city of Kaduna injured several people late on Sunday, the latest in a series of blasts in the north of Africa's most populous nation.
Witnesses said half a dozen people were wounded by the explosion at around 10:30 pm (2130 GMT) near a hotel in the Obalende district of Kaduna. A senior state security official said investigations were under way.
The explosion came hours after a bomb blast in Suleja, a satellite town on the outskirts of the capital Abuja, which killed three people and left seven badly injured.
Boko Haram, a radical Islamist sect which says it wants a wider application of sharia Islamic law, has claimed many of the recent attacks, most of which have taken place around the northeastern town of Maiduguri.
The strikes, which often target the police, churches and bars, have killed more than 150 people this year.
