South African miners, arrested after the Marikana shooting, have been released by a Pretoria court while key players refused to sign a deal to end a deadly strike.

More than a 100 miners were held in a South African jail after being charged last week under an obscure apartheid-era security law with murdering their fellow miners, after video footage indicated that police had fired on the strikers.

On Thursday, a key union representing the strikers as well as other non-unionised workers refused to sign a peace accord to resume wage negotiations, saying that it would force them to end their strike.
