Gunmen on Monday killed 15 farmers in Nigeria's northwest Katsina state, police said, in the latest violence by cattle thieves in the restive region.
Roughly 200 gunmen on motorcycles besieged the farmers in Yargamji village, 25 kilometres (15 miles) from the state capital Katsina, opening fire on them, police spokesman Gambo Isah told AFP.
"Fifteen bodies were recovered from the farms after the attack which was carried out by bandits," Isah said.
"They came on motorcycles numbering around 200."
Local residents confirmed the attack, adding that the assailants arrived around 1000 GMT and stopped at the crop fields outside the village where they opened fire on the farmers.
Isah said counter-terrorism personnel were sent to "engage the bandits".
Rural communities in Katsina, President Muhammadu Buhari's home state, have been repeatedly targeted by gangs of cattle thieves and kidnappers.
Last month, bandits killed 57 people in raids on several villages in the state.
Attempts by local authorities to broker peace with the criminal gangs have not been successful.
