Footage has appeared online showing South African police shooting and killing protesting platinum miners in South Africa.
The Guardian reports as many as 18 have been killed, and the clash follows earlier violence at the Lonmin-owned Marikana mine, where ten people have already been killed.
Lonmin is the world's largest platinum miner and the company has shut down the mine following the violence.
Workers claim they are fighting for better conditions but news reports claim the violence stems from a turf war between two unions.
Two policemen were previously killed in a machete attack near the mine and two security guards have also been killed in similar circumstances.
The Guardian has more in-depth reporting on this issue here and here.
