South African authorities have released some of the miners previously charged with murdering their colleagues shot dead by police.
The charges, brought under an apartheid-era law, were dropped yesterday following a national outcry.
Some 270 miners were originally detained more than two weeks ago during a wildcat strike at Lonmin’s Marikana platinum mine.
The shootings were the deadliest security incident since the end of apartheid in 1994. Police claimed they opened fire on the strikers in self-defence after being threatened by a crowd of protesters armed with machetes.
There has been no sign since of a breakthrough in the industrial dispute over pay.
