A man holds flowers during a memorial service for miners killed during clashes at Lonmin's Marikana platinum mine, in Rustenburg, 100 km (62 miles) northwest of Johannesburg, August 23, 2012. Labour unrest in South Africa's platinum belt spread on Wednesday, raising concerns that anger over low wages and poor living conditions could generate fresh violence after 34 striking miners were shot dead by police last week. The strike that started last week at Lonmin's Marikana mine has driven up platinum prices and stoked worries about investing in Africa's biggest economy, where chronic unemployment and income disparities threaten social stability.

Thousands of people packed a memorial service for 34 South African mine workers. They were shot by police in a dispute over pay. Host Marco Werman talks to the BBC's Nomsa Maseko who was at the service.
