The officials, who requested anonymity, said locals were still counting those abducted in the attack on Sunday in the remote, isolated area in Borno state, but that the figure could pass 100 and included women and children.
"After killing our youths, the fighters have taken away our wives and daughters," Mukhtar Buba said on Thursday, after fleeing Gumsuri to the Borno state capital Maiduguri.
Details took four days to emerge because the mobile phone network has largely collapsed in the area roughly 70km (43 miles) south of Maiduguri, and many of the roads are impassable.
Gamsuri is located on the road that leads to Chibok, where Boko Haram abducted more than 200 girls from a school in April.
One of the local officials said the village had previously been protected against Boko Haram violence by a strong vigilante force, but that they were overpowered in Sunday's attack.
"For the past one year, the fighters have made several attempts to attack Gumsuri but were resisted by the gallant youths of the village," he told AFP news agency.
"It is sad that on Sunday, the village was subdued," he added.
The military and police were not immediately available for comment.
Boko Haram has repeatedly attacked the vigilante forces which have formed across the northeast, describing them as legitimate targets for siding with Nigeria's military.
