Twenty years after combatants snapped arrows to signal the end of hostilities in the Papua New Guinea region of Bougainville, voters will on Saturday cast ballots in a long-awaited independence referendum.
The referendum terms were agreed as part of the peace process in the aftermath of a decade-long war, which was triggered by disputes over the now shuttered Panguna gold and copper mine, then run by a forerunner of giant mining company Rio Tinto.
