Four civillians have reportedly been killed in Papua province as Indonesian security forces continue their pursuit of the West Papua Liberation Army.
The Liberation Army claimed responsibility for killing as many as 31 Indonesians, mainly road construction workers, earlier this month in the Highlands region.
Local media reported that Indonesian military and police had retrieved 16 bodies from Nduga regency, having deployed a major joint operation there.
According to Tabloid Jubi, four Papuans were killed, including a priest of the Kingmi Church Synod, as troops sought to evacuate bodies of massacre victims.
There are humanitarian concerns for hundreds of Nduga residents - from Mbua, Yall and Yigi - who fled to the forest to avoid the joint operation.
Antara reported that Nduga's regent, Yarius Gwijange, said he had received unconfirmed reports that some civillians had been victims of "mis-shootings" of the joint operation.
He appealed to police and military to ensure civillians were not caught in the crossfire of their battle with the Liberation Army.
While the number of victims of the massacre remains unclear, the chairperson of Papua's Kingmi Church Synod, Benny Giay, said there were 24 people killed, all workers of a major road construction project.
Local people suspected the construction workers were military personnel, Dr Giay said.
This was because Indonesia's President Joko Widodo commissioned the military to build the major Trans Papua road network two years ago.
A spokesman for the Liberation Army last week said it attacked the workers after one of them was caught photographing a ceremony to mark the anniversary of 1961's West Papuan declaration of independence.
