The leader of striking miners (C) addresses his colleagues as they gather outside a South African mine in Rustenburg, 100 km (62 miles) northwest of Johannesburg, August 15, 2012. Thousands of striking miners armed with machetes and sticks faced off with South African police on Wednesday at Lonmin's Marikana mine after it halted production following the deaths of 10 people in fighting between rival unions.
