A group of rhino poachers has been eaten by lions on a South African game reserve.

A ranger taking guests at the Sibuya Game Reserve in the Eastern Cape on a safari drive on Tuesday afternoon discovered human remains close to a pride of lions, the owner of the lodge said.

"We suspect two were killed, possibly three," Sibuya owner Nick Fox said on Thursday.

In a Facebook post, Fox said he was immediately called to the scene where they found a high-powered rifle, wire cutters, food and water supplies as well as the remains spread over a large area near the lions.
