Last South African miners freed after charges dropped

The second and final batch of South African miners have been freed after controversial murder charges were dropped following a national outcry.

The 106 miners are set to return to the Marikana mine, where police shot dead 34 striking workers last month.

A militant union has refused to sign a "peace accord" with the government and mine owner Lonmin, insisting that it will remain on strike until its pay demands are met.
