This was a significant move towards a free and fair election in the coming Bougainville Referendum.
The ceremony took place last week at the Emeu District Station in Siwai District of South Bougainville.
Former combatants from the area came together to reconcile and strengthen unity.
It was a stage 5 of weapon disposal and reconciliation – a final stage 6 will be held later in the year.
Chairman of the Siwai District Peace Committee, Peter Tengka, thanked South Bougainville MP, Timothy Masiu, for contributing K20,000 towards the event.
