Maiduguri - Security agents say suspected Boko Haram members have gunned down 44 people praying at a mosque in a town 35km from Maiduguri.
The mosque was located in Konduga town.
A state security service agent and a member of a civilian vigilante group working with the military said on Monday they counted the bodies at the mosque after Sunday morning's attack.
The state security agent spoke on condition of anonymity because he was not authorised to talk to reporters.
Usman Musa of the civilian group says four of its vigilantes were also killed when they responded to calls for help.
