Papua New Guinea's Prime Minister says the people responsible for a violent attack on a trekking group should face the death penalty.
In the assault on Tuesday in the Papua New Guinea highlands, two local porters were hacked to death, and a New Zealander and several Australian trekkers injured.
Peter O'Neill says he makes no apology for calling for the death penalty and describes the attack as an appalling crime.
He also plans to introduce tourist police specifically to protect visitors, such as trekkers.
"I am in fact looking at the same arrangement that places like Bali has where they have tourist police. We are looking at working closely with tourism promotion authority with a concert of policing so when trekkers are going out, police men and women can accompany them."
Peter O'Neill says tourism is a strong revenue earner for Papua New Guinea.
