The insurgents, riding on motorcycles, opened fire on farmers working in their fields in Ngawo Fato Bulamari village outside the state capital Maiduguri, the epicentre of the eight-year jihadist rebellion.

"The Boko Haram gunmen while riding past the farmlands opened fire," said Babakura Kolo, a member of a militia force fighting the jihadists, of the incident which happened on Monday.

"Four people were killed while many have gone missing and our assumption is that they ran into the bush to escape the attack," Kolo said.

A militia leader, Ibrahim Liman gave a similar account, saying at least one of the missing farmers later returned to the village.

Last week, a farmer was shot dead while four others were abducted by the Islamists near the town of Konduga, some 40 kilometres from Maiduguri.

The victims were among a group of 20 farmers from a nearby village who went to their fields despite a security warning by the military.
