Nigerian police say attackers killed 16 people in a mostly Christian village late Friday.
The attackers also set fire to more than one dozen homes in the village in Bauchi state.
Nigeria has a history of deadly clashes between Muslim and Christians.
Last month, riots broke out in the predominantly Muslim north after incumbent President Goodluck Jonathan, a Christian from the south, won reelection.
Supporters of his challenger in the race, Muhammadu Buhari, attacked churches, homes, and a police station, sparking counterattacks by Christians.
Media reports say more than 100 people were killed in the violence, though officials have declined to give a death toll for fear of prompting more attacks.
Some information for this report was provided by AP, AFP and Reuters.
