Police said since March 2016, about 25 people have been killed when the conflict erupted in KwaMadondo and eNhlawe villages, with five being murdered last month.
Mvuseni Mkhwanazi, a community leader, said the bloodbath was triggered by a multibillion-rand oil project proposed in the village.
"This village has not enjoyed peace. The killings started after Ngwane and Makhanya were removed from a local committee of the emerging contractors. They were suspected of being involved in corruption. Shortly after that, community activists who wanted the entire community to benefit were targeted and killed. The killing spilt over to other ordinary people of the community," said Mkhwanazi.
Ngwane and Makhanya are out on bail and are due back in court next month.
RBM spokesperson Zanele Zungu said the company was aware of the killings but they knew nothing about the alleged pending oil project.
"We are not aware of any proposed oil project in the area. In all of our projects we ensure that the community and the traditional leadership are sufficiently consulted to avoid any clashes. Projects are meant to develop the community and provide jobs, they should not result in deaths."
