Marikana mine strike: Court frees some arrested miners

About 50 South African miners held over the Marikana killings have been freed after murder charges against them were dropped.

This comes a day after prosecutors provisionally dropped charges against 270 of the striking mineworkers following a public outcry.

About 100 miners are expected to be freed on Monday.

Earlier, security guards wounded four people with rubber bullets at a mine near of Johannesburg, police said.
