Scores of primary and secondary school students have been lined up for the rite in various parts of the region despite spirited efforts by government to clamp down on those promoting the vice.
Kiyapyap said it was unacceptable that in Elgeyo Marakwet, the region was hardest hit by FGM activities. "We will not relent in the fight against the promotion of this outdated culture among the local community," she said.
