Gunmen have killed 15 village traders returning from a market at night and set their bodies ablaze in northern Nigeria's Zamfara state, a local police chief said on Friday.
"Gunmen, suspected to be armed robbers, attacked some local traders on their way back from a market in neighbouring Katsina state late Thursday," Zamfara state police commissioner Tambrai Yabo told AFP.
"The armed robbers waylaid the traders travelling back in an open truck and opened fire on them. They then loaded the truck with 14 bodies and burnt them," said Yabo, adding that a 15th victim had died in hospital.
Villagers said around 100 robbers came out of the bush and forced the truck to stop. The attack ocurred near a village that is close to the town of Birnin Magaji in Zamfara state, which borders Niger.
Armed robberies have been on the rise in Zamfara in recent months.
In October, marauding bandits combed a village in Lingyado and killed 19 people in response to an attack on a gang of robbers by local vigilantes, residents said.
In December, four policemen and two children from one family were killed by armed men in Dansadau village.
Zamfara is around 350 kilometres west of Kano city, where Islamist sect Boko Haram killed 185 people in a wave of gun and bomb attacks a week ago.
