JOHANNESBURG (Reuters) - South Africa's Harmony Gold stopped all its operations for a 24-hour safety shift on Friday after at least eight workers were killed in a rock-fall and fire, the worst accident in South Africa's mines in nearly five years.
In addition to the accident at its Doornkop mine near Johannesburg, South Africa's third-largest bullion producer said two other workers had died in separate incidents at different mines on Thursday.
