The Chibok community leader, Pogu Bitrus, said other kidnapped girls may have been rescued by soldiers hunting down the extremists in the northeastern Sambisa Forest.
Bitrus said he is working with officials to verify identities.
In April, a video by CNN appeared to show some of the kidnapped Chibok girls alive. The footage was allegedly taken at Christmastime in 2015. Some of the girls in the video were identified by their parents.
The number of children and young women kidnapped by the extremist group is not known, although it is believed to be in the thousands. Nigerian officials have reported saving thousands this year, as they push Boko Haram from towns to the Sambisa Forest.
Suicide Bombing
The 7-year-old extremist group has killed 20,000 people, and has turned to soft targets by using suicide bombers.
The number of children involved in Boko Haram suicide attacks has increased dramatically, said a UNICEF report on April 12.
The number increased from 4 in 2014—to 44 in 2015. UNICEF reported that over the past 2 years, 1 in 5 suicide bombers was a child and 75 percent of the children involved in Boko Haram attacks were girls.
The Associated Press contributed to this report.
