Indonesian officials say PNG soldiers used excessive force when they shot and killed an Indonesian fisherman and injured two others near the two countries' northern sea border.
The body of the 27-year-old fisherman, named as Mulydi, has been returned to family members in Indonesia's Papua province following Tuesday's incident.
The shootings occurred after a coastal border patrol of PNG soldiers and police chased a motorised canoe carrying 10 Indonesian fishermen allegedly fishing illegally in PNG waters.
The chief of staff of the PNG Defence Force, Captain Tom Ur, says soldiers and police had been asked to join one of the regular fisheries patrols near the border town of Vanimo.
He says they came upon around 12 boats and pursued them when they failed to stop.
"They fired a few warning shots but these guys continued trying to escape, so the next thing they did was try for the outboard motor. I think because of the unstable platform they got the guy sitting at the back."
