A South African union representing striking platinum miners is holding wage talks with employers amid reports of some confrontations around the mines.
Union representatives on Friday met senior managers of mining companies to discuss worker demands for higher wages in one of South Africa's major industries. South Africa is the world's top producer of the platinum, which is used in medical, electronic and other industries.
Tens of thousands of platinum miners went on strike on Thursday.
Eyewitness News, a media outlet, reported confrontations between striking miners and mine security officials in one area, as well as incidents of protesters blocking roads and throwing stones at motorists.
In 2012, South African police shot and killed several dozen miners during labor unrest. An inquiry is underway.
