Boko Haram has kidnapped at least 185 people, including women and children, in northeast Nigeria, the latest mass abduction in a region where the military has repeatedly struggled to protect civilians.
The attack, conducted on Sunday by well-armed Islamist extremists in the town of Gumsuri, also killed 32 people.
It recalled the April kidnappings in Chibok, where more than 200 girls were taken from a school.
President Goodluck Jonathan, who is standing for re-election in February 14 polls, had pledged that the Chibok attack would mark the beginning of the end of terrorism in Nigeria, but violence has escalated since.
The Islamists have a carried out a series of abductions this year, boosting their supply of child fighters, porters and young women who have reportedly been used as sex slaves.
Boko Haram has not claimed the Gumsuri attack, but multiple sources in the village blamed the extremists, whose five-year uprising has killed more than 13,000 people and forced more than 1.5 million others from their homes.
Northeast Nigeria has been the epicentre of the conflict, but unrest has also spread into neighbouring Cameroon, where the military claimed to have killed 116 insurgents while repelling a Wednesday attack on an army base in the border town of Amchide.
A convoy of gunmen stormed Gumsuri in Borno state on Sunday, throwing petrol bombs into buildings and leaving much of the village destroyed, two local officials and a witness said.
The officials, who put the death toll at 32, said the local government established the number of those abducted by contacting families, ward heads and clerics.
A vigilante leader based in the Borno state capital Maiduguri, Usman Kakani, said that fighters who were in Gumsuri during the attack provided a figure of 191 abducted, including women, girls and boys.
Gumsuri is roughly 70 kilometres south of Maiduguri on the road that leads to Chibok.
Details of the attack took four days to emerge because the mobile phone network in the region has completely collapsed and many roads are impassable.
Mukhtar Buba, a resident who fled to Maiduguri, confirmed that women and children were taken. "After killing our youths, the insurgents have taken away our wives and daughters," he said.
The military and police were not immediately available to comment.
Witnesses said the hostages were carted away on trucks towards the Sambisa Forest, a notorious rebel stronghold, where the Chibok girls were also reportedly taken before being divided into smaller groups.
Vigilantes, who have the military's backing, had defended Gumsuri against waves of previous Islamist attacks but were ultimately overpowered on Sunday, local officials said.
Soldiers on the ground have complained of being used as cannon fodder in battles against militants armed with rocket-propelled grenades and heavy artillery.
