Nigerian security forces have denied reports that 60 girls and women and 31 boys have been abducted in the northeast of the country.
There is no way to safely and independently confirm the report from Kummabza, located 95 miles from the capital of Borno state, the Associated Press reported.
Aji Khalil, of a local anti-Boko Haram group, told AP the abductions took place Saturday in an attack in which four villagers were killed.
The Associated Press has reported on Twitter:
BREAKING: Witnesses say extremists have abducted 60 more girls and women, 31 boys in northeast Nigeria.
Suspected Islamist militants attacked a village in northeast Nigeria, killing "many" as they fired at villagers and torched houses, a witness told Reuters news agency.
The attackers stormed the village about 9 km (6 miles) from Chibok, where nearly 300 school girls were abducted by an Islamic militant group in April.
Nigerian families have been reunited with 57 of the girls abducted by Islamist militant group Boko Haram but over 200 are still missing, the government said.
Some 219 girls remain at large after the mass kidnapping in April, Brigadier General Ibrahim Sabo, who is chairman of the government's fact-finding committee on the kidnapping, said in a statement.
There are fears the Nigerian terrorist group Boko Haram could be spreading south, after security forces found a senior member in a convoy of nearly 500 travellers arrested this week in the southern state of Abia. Traditionally, the group has been largely confined to the Muslim north.
It also raises the concern that the group, which drew worldwide attention in April when it kidnapped more than 200 girls from a school in northeast Nigeria, could eventually attempt attacks in the oil-rich Niger delta.
Officials said on Monday that nearly 500 people believed to be northerners had been arrested overnight while travelling through the south in a convoy of more than 30 vans.
Boko Haram are suspects in the bombing of a Nigerian television bar yesterday, in which 13 people died while watching a World Cup game. No one has yet claimed responsibility, however.
