Co-workers of 34 miners shot dead by South African police during a violent wage strike pray during a ceremony to mark the first anniversary of their deaths on August 16, 2013 in Marikana. Today marks a year after police opened fire on thousands of strikers at platinum producer Lonmin's mine, northwest of Johannesburg, which killed 34 and injured 78 people. The August shooting was described as the worst police brutality since the end of apartheid two decades ago.
