Officials in Nigeria say more than 20 people were killed when gunmen believed to be Boko Haram militants attacked a village in the country's northeast.
Residents in the town of Daku say gunmen surrounded the village market on Sunday and fired indiscriminately at people.
The violence is the latest to hit Nigeria's troubled northeastern region.
Militants from Boko Haram are holding more than 200 schoolgirls they kidnapped from the nearby town of Chibok in mid-April.
The militants also have killed thousands of people during their 5-year insurgency to establish an Islamic state in Nigeria's northeast, with attacks on schools, churches, mosques, bus stations and other public places.
The Nigerian government has struggled to contain Boko Haram, despite a state of emergency in the northeast and deployment of thousands of troops to the area.
It also is facing growing criticism that it is not doing enough to rescue the kidnapped schoolgirls or prevent more attacks.
