The attacker set off her explosives among a group of men at a hangout next to the local chief’s home, said Ibrahim Liman, an anti-jihadist militia leader who gave the same toll.
Konduga and surrounding villages have been repeatedly targeted by suicide bombers from Boko Haram, which typically attacks soft civilian targets such as mosques, markets and bus stations, often using young women as bombers.
At least 30 people were killed last year in Konduga when three bombers detonated their explosives outside a hall where football fans were watching a match on TV.
Boko Haram and a splinter group, the Islamic State West Africa Province (ISWAP), have killed 36,000 people and displaced around two million since 2009.
The jihadist conflict has spread into neighbouring countries like Chad, Niger and Cameroon, prompting a regional military coalition to end the violence.
