Nigerian authorities say the Boko Haram militant group kidnapped 100 people, and most were freed by security forces from neighboring Cameroon.
A Nigerian security official said the abductions took place on Aug. 10 in Doron Baga in the Kukawa local government area, near the border with Cameroon.
He said Cameroonian security forces intercepted the group, killed many of the fighters and freed most of those abducted. He spoke on condition of anonymity because he was not authorized to speak to the media.
Muhammed Gava, a member of the anti-Boko Haram vigilante movement, said 20 females and about 70 young men were forced to board speed boats in Lake Chad, which lies on the border between Nigeria, Niger, Cameroon and Chad.
