Two porters with a group of trekkers in Papua New Guinea have been killed in an attack on the Black Cat Track in Morobe Province.
The group included trekkers from Australia, New Zealand and PNG.
After the attack the eight Australians and one New Zealander walked for 4 hours to Wau to raise the alarm.
A spokesperson for the Morobe Mining Joint Venture, Stanley Komunt, says there were another 10 porters injured - all with knife wounds.
None of the foreign trekkers suffered life threatening injuries.
The Black Cat Track, which was the scene of bitter fighting between Australian and US troops and Japanese forces in 1943, is regarded as one of the most arduous walks in PNG
