More than 100 miners escaped from a gold mine in South Africa on Wednesday after being held underground for three days by fellow employees in a union dispute, a company official said. Around 450 workers remain in the mine, the official said, with an unknown number of them preventing the others from leaving as they demand formal recognition of their labor union. The union - The Association of Mineworkers and Construction Union - gave another version of the events and says the miners were staying underground willingly as a protest in support of the union.
