Mingi is defined as being impure or cursed in certain African tribes in the Omo River Valley in Ethiopia, including the Kara and Hamar tribes. Unfortunately, these tribes participate in the tribal ritual of killing children that are declared Mingi.A child can be declared Mingi for the following reasons — Teeth Mingi, Girl Mingi, Woman Mingi and Twin Mingi.
