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".
The basic education minister said it was an "indignity [which] goes against the values of our cultures".
But the choirmaster has defended the choice - saying he was proud.
According to South Africa's Daily Dispatch website, the unnamed teacher said: "We are proud of our Xhosa tradition. We are proud of 'inkciyo'. We are proud of Xhosa women and girls."
The Xhosa are South Africa's second-largest ethnic group. Footage of the performance at a competition in Mthatha, in the Eastern Cape, emerged earlier this week, showing the girls dancing on stage, their breasts and buttocks exposed.
