Eighty children Boko Haram kidnapped and brainwashed can't remember their own names and have little recollections of their past, an aid official who met them after their rescue has revealed.
The startling discovery was made by National Democratic Institute's Christopher Fomunyoh, who says the kids spent so much time in militants' captivity and were subjected to such powerful doses of mind-altering indoctrination that they have forgotten their identities.
In an interview with BBC, Fomunyoh said: "They've lost touch with their parents. They've lost touch with people in their villages, they're not able to articulate, to help trace their relationships, they can't even tell you what their names are."
While Boko Haram was formed in Nigeria in 2002, it has since branched out into Cameroon, Niger, Chad and Benin. With its aim being to forcefully establish an ISIS-style Islamic caliphate, the terror group often distorts religious ideologies of young minds to lure them into committing acts of mass terrorism later.
Aged between 5 and 18, the 80 children in their captivity were perhaps being readied for future use before Cameroon forces raided a madrasa (Quranic school) and rescued them.
As of June 2014, Boko Haram had killed 5,000 people, although that number must have gone up significantly now that they have amped up their activities and are in direct military conflict.
Before pledging allegiance to ISIS last week, Boko Haram launched at least five major assaults on villages and military forces in the countries fighting against them.
