Suspected Boko Haram gunmen killed 10 people who had fled their homes to escape repeated attacks by the insurgents, after hunting them down in a nearby village, witnesses said on Monday.
Residents of Krenuwa village fled to nearby communities after a Boko Haram raid last month that left seven dead and saw the extremists raze a military camp, police station and several homes.
About a dozen militants stormed the villages of Durwa and Maforo in the Marte district on Sunday, where some of them were seeking refuge.
"They came on motorcycles and gathered people before singling out their victims who moved in from Krenuwa after it was attacked", said Usman Ari, a Durwa resident.
"They shot six of them dead and slaughtered four," said Ari, who fled to the Borno state capital, Maiduguri, some 100 kilometres (60 miles) away after the attack.
