South Africa outrage over 'naked' school choir performance

The footage emerged earlier this week at a competition showing the girls dancing on stage, their breasts and buttocks exposed

A "naked" choir performance by a group of South African schoolgirls has led to calls for investigation by the country's education minister.

Angie Motshekga said she was "extremely disappointed" after seeing footage of the Xhosa girls performing wearing only a small apron, known as an "inkciyo".
