A South Africa minister has apologized after being accused of beating up a woman called him gay. "I will also meet with my organisation‚ the ANC‚ and President Zuma to give a full account of the incident".
He said while he was provoked, he "should have exercised restraint". The media statement adds that the president must show that he is serious about fighting the scourge of violence and abuse against women.
"Such behaviour is unacceptable and should be roundly condemned by all in our society. While we take into account the principles of innocent until proven guilty, the ANCWL is resolute in supporting the victims of violence and wishes to reiterate this position".
