Islamic extremists have abducted 60 more girls and women and 31 boys from villages in northeast Nigeria, witnesses said Tuesday.
Security forces denied the kidnappings. Nigeria's government and military have attracted widespread criticism for their slow response to the abductions of more than 200 schoolgirls kidnapped April 15, AP reported.
There was no way to safely and independently confirm the report from Kummabza, 150 kilometers (95 miles) from Maiduguri, capital of Borno state and headquarters of a military state of emergency that has failed to curtail near-daily attacks by Boko Haram fighters.
Kummabza resident Aji Khalil said Tuesday the abductions took place Saturday in an attack in which four villagers were killed. Khalil is a member of one of the vigilante groups that have had some success in repelling Boko Haram attacks with primitive weapons.
A senior local councilor from the village's Damboa local government told The Associated Press that abductions had occurred but requested anonymity because he was not authorized to give information to reporters. He said elderly survivors of the attack had walked some 25 kilometers (15 miles) to the relative safety of other villages.
The Damboa council secretary, Modu Mustapha, said he could not confirm or deny the abductions and directed a reporter to the council chairman, Alamin Mohammed, who did not answer phone calls or respond to text messages.
Boko Haram has been demanding the release of detained members in exchange for its hostages but President Goodluck Jonathan has said he will not consider a swap.
A strategy to rescue the girls appears to have reached an impasse. Nigeria's military has said it knows where they are but fears their abductors would kill them if any military action is taken.
Politics have bedeviled the issue, with many distracted by upcoming presidential elections in February 2015. The first lady, Patience Jonathan, and some other supporters have claimed the reports of the April abductions of the schoolgirls were fabricated to discredit her husband's administration.
Last week, a presidential committee investigating the kidnappings stressed that they did in fact happen and clarified the number of students who have been kidnapped. It said there were 395 students at the school, 119 escaped during the siege of the school, another 57 escaped in the first couple of days of their abduction, leaving 219 unaccounted for.
This year, the Boko Haram insurgents have embarked on a two-pronged strategy - bombing in cities and a scorched-earth policy in rural areas where they are devastating villages. Nigeria's capital, Abuja, the central city of Jos and the northeastern state capital of Maiduguri, the birthplace of Boko Haram, all have been bombed.
On Monday, an explosion at a medical college in the northern city of Kano killed at least eight people and wounded 12, police said. It was the third bomb blast in four months in Kano, Nigeria's second city.
Also on Saturday, the same day as the latest abductions, scores of Boko Haram fighters attacked four other villages, near Chibok town from which the girls were kidnapped. Witnesses said at least 33 villagers were killed as well as six vigilantes and about two dozen Boko Haram fighters.
