The Islamic extremists targeted the women of Gagalari, in Yagoua Diocese during the night, kidnapping them from their homes and cutting off their ears, according to Catholic charity Aid to the Church in Need (ACN).
ACN's source said: "They arrived during the night, entered the houses one by one and kidnapped the women. Only the women.
"They took them to the outskirts and amputated one ear of each of the victims.
"Then they released them threatening them and telling them that they would return, that this is the first [such] intervention, but others will follow. It is terrifying."
Armed forces then took the victims 160 miles away from the village, to receive medical care.
According to local news reports, Boko Haram fighters drove away members of the Vigilance Committee who tried to stop them.
The source said: "It was no use in this repulsive surprise attack. The women were dragged out of their homes before the eyes of their children."
Two other villages in the area were reportedly attacked by Boko Haram in the days leading up to the Gagalari raid in which three members of a local Vigilance Committee were killed.
