One of the villages that were attacked between last night and early today lies near the town of Chibok, where more than 300 schoolgirls were kidnapped last month.
The reports came from residents and were confirmed by a state intelligence agent who spoke on condition of anonymity because he is not authorised to give information to reporters.
Apagu Maidaga of Alagarno village said residents hid in the bush and watched while the extremists set ablaze their homes of thatch-roofed mud huts.
In Jos, where 118 people were killed in twin car bomb attacks Tuesday on a bustling bus terminal and a market, rescue workers armed with body bags today dug into the rubble of destroyed buildings.

Most victims were women and children vendors, said Mohammed Abdulsalam of the National Emergency Management Agency.
"We expect to find more bodies in the rubble," Abdulsalam said.
Jos is tense with fears the attack blamed on Islamic extremists could inflame religious rivalry. The city in central Nigeria sits on a volatile fault line dividing Nigeria's mainly Muslim north from the predominantly Christian south and has been a flashpoint in the past for deadly conflict between adherents of the two religions.
Officials in at least three other central and central-north states have suggested the extremists are feeding into local tribal and religious tensions to spread the insurgency from its stronghold in the northeast into an area where thousands have been killed in recent years in disputes over land, water, religion and tribe.
President Goodluck Jonathan indicated that he blames Boko Haram for Tuesday's attack, assuring Nigerians their government "remains fully committed to winning the war against terror." Jonathan has been saying that for years, despite the lack of results.
