Civil rights organisation AfriForum has condemned Kommando korps training camps.
On Friday, the Mail & Guardian newspaper reported that a camp outside Carolina, Mpumalanga, was training teenage boys to hate black people.
The camp, called Kommando korps, claims to have trained over 15-hundred boys aged 13 to 19.
AfriForum CEO Kallie Kriel said the treatment of the boys was immoral and inexcusable.
He said it was regrettable that a small fringe group's actions can time and again be used to try and portray all Afrikaners in a bad light.
