Sunday's attack in Benisheik, 72 kilometers (45 miles) west of Maiduguri, took place days after the military says it killed at least 50 insurgents in an area to the north.
Zannah Fannami, an injured operative with the Civilian Joint Task Force, said they were attacked while awaiting Boko Haram's approach on the town. He said the vigilante group was able to kill five of the suspected Islamic sect members. Another Civilian-JTF operative Muhammed Abuwar said the military didn't assist the vigilantes and 18 others were injured.
Though the military couldn't be immediately reached for comment, the road leading to Benisheik was barricaded.
