Mine supervisors held hostage freed
Four supervisors being held hostage by 500 miners in an underground protest have been released, the management of a platinum mine in South Africa has said.
The miners are holding a "sit-in" 30 metres (100 feet) below the surface at Eastern Platinum's Crocodile River mine northwest of Johannesburg.
Charmane Russell, a spokeswoman for the Canadian-based mining company, said the supervisors were released early on Friday evening.
Eight supervisors were initially being held when the protest began on Thursday morning in a deeper shaft, but four managed to escape using underground tunnels.
Miners' union official Stheti Mxhasi has denied workers took any hostages and said management had cut water supplies to the protesters, a claim the mine denies.
The workers, who are contracted to the mine through other companies, are demanding to be made full-time employees.
