The vice president of the autonomous government of Bougainville in Papua New Guinea says the former Fijian soldiers who have been proving training for people associated with the scam operator Noah Musingku, are causing more trouble.
15 Me'ekemui militants, thought to be linked to Mr Musingku, have fired at police manning a checkpoint in southern Bougainville.
Joseph Watawi says two former Fijians soldiers were with them.
The Fijians are part of a group of five who have been providing Mr Musingku's men with military training.
Mr Watawi says he has asked the Fiji High Commission to try to get the former soldiers to return home because they are affecting the stability of the province.
"They have been practically involved in this illegal activty and it is really a concern and I think it is a concern that is also shared by the Fijian government and what their citizens are doing here to destabilise the peace."
