JOHANNESBURG, Oct 2 (Reuters) - Petra Diamonds said on Tuesday that a "limited number" of workers at its Kimberley Underground mine had gone on strike, although production had not been affected.
A spokeswoman for the London-listed company said in an e-mailed statement that the strike had started on Tuesday and the company was in talks with the National Union of Mineworkers.
